Japan local-government bond market issuance matrix (prefectures / 政令指定都市 / municipalities / special districts)

TL;DR

Japan’s local-government bond market is not one issuer class. It is layered across four issuer tiers — 47 prefectures (都道府県), 20 政令指定都市 (designated cities), roughly 1,700 ordinary cities / towns / villages (市町村), and special districts / public enterprise authorities — with very different issuance scales, channel mixes, credit profiles, and JFM dependence. Tokyo Metropolis (都債) sits at the apex as the benchmark for the asset class and rarely uses JFM; mid-sized prefectures like Osaka, Aichi, and Kanagawa run material public-offering programs but also use joint-issuance and JFM; smaller prefectures rely heavily on JFM / FILP / bank-underwritten channels; most small municipalities are entirely outside public-offering markets. This matrix collects publicly-verifiable axes — issuer count, typical issue size, JFM reliance, FILP reliance, MIC (総務省) supervision role, secondary-market liquidity, yield-spread to JGB benchmarks, and foreign-investor participation — across the four tiers and against named benchmark issuers (Tokyo Metropolis, Osaka Prefecture, Aichi Prefecture, prefecture average, Yokohama City, Osaka City, Nagoya City, the joint-issuance pool, and the JFM bond complex).

Wiki route

This entry sits under policy-finance index as the issuer-type and credit-profile matrix paired with Local government bond market (market-level entry), JFM (joint-funded public-credit institution), Japan Local Government Bond Association (industry-association anchor), and Tokyo Metropolitan Bond (benchmark-issuer case study). It complements the credit-guarantee public-credit lane at Japan credit guarantee system / Tokyo Credit Guarantee Corp / Osaka Credit Guarantee Corp (which sit on the SME-credit side rather than the local-bond side) and routes to the banking-domain entry on regional bank consolidation pattern (since regional banks hold material local-bond exposure), the money-market index page JGB repo market (local bonds and JFM bonds serve as collateral), Japan money market, and the broader finance index route through Japanese listed financial groups for institutional-holder context.

Why this matrix matters

A single phrase like “Japanese local-government bond” hides almost every axis that matters for analysis:

Issuer tier controls market access. A Tokyo Metropolis bond and an under-10,000-population village bond are not in the same asset class. Public-offering channel, joint-issuance channel, JFM channel, FILP channel, and bank-underwritten channel each apply to different issuer tiers in different proportions.
Credit logic differs by tier. A prefecture’s credit rests on its tax base + Local Allocation Tax (地方交付税) status + statutory fiscal-soundness indicators; a designated-city’s credit rests on its tax base + LAT + intra-prefectural fiscal relations; an ordinary-city / town / village’s credit rests heavily on LAT + statutory consultation system + JFM / FILP support. Foreign-investor participation tracks back to this differentiation.
JFM dependence varies sharply. Larger prefectures and designated cities use JFM modestly; smaller prefectures use it materially; most ordinary-city / town / village borrowers rely heavily on JFM and FILP for long-tenor lending.
MoF (財務省) and 総務省 (MIC) play different supervisory roles. MIC operates the statutory consultation system (協議制度) for bond issuance and administers LAT; MoF manages FILP (財政融資資金) as a parallel direct-lending channel. MIC is the dominant local-finance supervisor; MoF is the dominant capital / fiscal supervisor.
Yield-spreads to JGBs are tier-differentiated. Tokyo Metropolitan Bond spreads are the tightest reference; joint-issuance bonds price modestly wider; named-prefecture public-offering bonds price tier-by-tier with material variation by issuer; JFM bonds price as a separate high-grade public-credit asset; smaller issuers rarely access public-offering markets at all.
Foreign-investor participation is concentrated. Foreign holders concentrate on Tokyo Metropolitan Bond, joint-issuance bonds, JFM bonds, and selectively on the largest named-prefecture and designated-city issuers; small-issuer bonds are almost entirely domestic-investor held.

Without the issuer-tier and channel-mix axes, treating “local-government bond” as one asset class produces analytical errors.

Issuer Tier 1 — Tokyo Metropolis (東京都 / 都債)

Issuer category. 都 (prefecture-equivalent special-administrative unit). One of only 47 prefecture-equivalent issuers but structurally distinct — see Tokyo Metropolitan Bond page for the dedicated treatment.
Tax-base scale. Local tax revenue base larger than many sovereign nations; historically a 不交付団体 (non-recipient of 地方交付税).
Issuance program. Large recurring public-offering program across plain-vanilla maturities (2y, 5y, 10y, 20y, 30y selectively), joint-issuance pool participation is selective, sustainability / green / SDG-labelled tranches issued in size, retail-targeted issuance series for Tokyo residents.
Typical issue size. Public-offering tranches commonly ¥30–100 billion per series with periodic large primary issuance windows.
Annual issuance volume. Public-offering issuance routinely ¥1–2 trillion+ across all programs; benchmark-issuer status keeps the market well-supplied.
JFM reliance. Low. Tokyo Metropolis has open market access and uses JFM proportionately less than smaller issuers.
FILP reliance. Low to moderate, mostly for specific long-tenor public-enterprise lanes.
MIC consultation role. 協議 procedure (consultation with MIC) applies but Tokyo’s market access is unconstrained; the consultation is a statutory check, not a binding limit.
MoF role. Administers FILP capacity allocation; coordinates on capital-market-related matters with MIC.
Secondary-market liquidity. Highest among local-bond issuers — the benchmark for the asset class; spreads to JGB are quoted as the natural reference.
Yield-spread to JGB benchmarks. Tightest among local-government issuers; spread to 10y JGB historically in the low-single-digit basis-points range during stable markets, widening modestly under stress.
Foreign-investor participation. Material — Tokyo Metropolitan Bond is the most-held local-bond by foreign institutional holders, particularly the labelled sustainability / green tranches.
Implicit-support read. Investors price as if national-government implicit support exists; the legal reality is more limited (repayment depends on Tokyo Metropolitan tax revenue and statutory frameworks).

Issuer Tier 2 — Major prefectures (大規模都道府県 — Osaka, Aichi, Kanagawa, Hokkaido, Saitama, Chiba, etc.)

Issuer category. 47 都道府県 minus Tokyo; large urban / industrial prefectures sit in this tier with material public-offering programs.
Tax-base scale. Substantial local-tax bases — Osaka, Aichi, Kanagawa, Saitama, Chiba have urban / industrial tax bases supporting public-offering programs; Hokkaido, Hyogo, Fukuoka, Shizuoka, Hiroshima similarly run public-offering programs alongside larger LAT / JFM reliance.
Issuance program. Public-offering program in plain-vanilla maturities, joint-issuance pool participation (the joint-issuance system pools smaller-scale issuance), bank-underwritten (銀行等引受) private placements, JFM lending for specific public-enterprise lanes, FILP for long-tenor specific uses, sustainability-label issuance growing.
Typical issue size. Public-offering tranches commonly ¥20–50 billion per series; joint-issuance share supplements scale.
Annual issuance volume. Public-offering issuance ¥300 billion–¥1 trillion+ range depending on prefecture; combined with JFM / FILP / bank-underwritten the total annual finance need is materially larger.
JFM reliance. Moderate. Large prefectures still draw on JFM lending for public-enterprise (water, sewerage, urban transit) and specific infrastructure lanes.
FILP reliance. Moderate, depending on specific-purpose lending programs and disaster-recovery framing.
MIC consultation role. 協議 procedure applies; issuance plans coordinated with MIC under the statutory consultation system.
MoF role. FILP allocation; capital-market coordination via MIC.
Secondary-market liquidity. Tight in named-prefecture benchmark issues for major prefectures (Osaka, Aichi, Kanagawa); wider for smaller named-prefecture issues; joint-issuance pool provides liquidity supplement.
Yield-spread to JGB benchmarks. Modestly wider than Tokyo Metropolis; named-prefecture 10y spread typically in the low-to-mid single-digit basis-points range vs JGB; wider under stress; joint-issuance pool prices typically a few basis points wider than named-prefecture benchmark issuers.
Foreign-investor participation. Modest — Osaka Prefecture, Aichi Prefecture, Kanagawa Prefecture public-offering bonds attract some foreign institutional interest; smaller-prefecture named issuance is almost entirely domestic-held.
Specific issuer notes.
- Osaka Prefecture (大阪府 / 大阪府債). Large recurring public-offering program; 2025 Osaka-Kansai Expo-related infrastructure finance was a notable spike. Tax base is industrial / commercial-led but has historically been weaker than Tokyo, supporting wider spreads.
- Aichi Prefecture (愛知県 / 愛知県債). Large industrial (auto-cluster) tax base; recurring public-offering program; spreads typically among the tightest behind Tokyo Metropolis given the prefecture’s industrial credit profile.
- Kanagawa Prefecture (神奈川県 / 神奈川県債). Substantial urban-industrial tax base; recurring program; foreign-investor participation modest but present.
- Hokkaido (北海道). Receives 地方交付税 (LAT); recurring but smaller public-offering program; JFM and FILP reliance materially higher than non-LAT prefectures.

Issuer Tier 3 — Mid- and small-prefecture issuers

Issuer category. Remaining prefectures — mid-sized (Niigata, Nagano, Shizuoka-not-major, Mie, Okayama, Hiroshima, Kumamoto, Kagoshima, etc.) and smaller (Tottori, Shimane, Tokushima, Kochi, Saga, Miyazaki, etc.).
Tax-base scale. Smaller and / or aging tax bases; most are net recipients of 地方交付税 (LAT).
Issuance program. Smaller public-offering program (some prefectures have minimal direct public-offering access); joint-issuance pool participation is the primary public-offering channel for many; JFM lending is structurally important; FILP for specific-purpose long-tenor lending; bank-underwritten (regional bank, shinkin) lending substantial.
Typical issue size. Smaller direct-public-offering tranches (¥5–20 billion when issued) or zero direct public-offering — joint-issuance is the primary route.
Annual issuance volume. Variable; many small prefectures’ total annual issuance fits within the joint-issuance / JFM / FILP / bank-underwritten envelope rather than direct public offering.
JFM reliance. High to moderate. Smaller prefectures rely materially on JFM for long-tenor low-cost lending against local-government bond obligations.
FILP reliance. Material, particularly for specific-purpose long-tenor lending and disaster-recovery lanes.
MIC consultation role. 協議 procedure applies; for some smaller issuers under specific fiscal-soundness conditions the statutory regime requires 許可 (authorization) rather than just consultation.
MoF role. FILP capacity allocation more material for this tier given higher FILP reliance.
Secondary-market liquidity. Limited in direct named-prefecture bonds; joint-issuance pool provides better liquidity; JFM bonds for the underlying lending portfolio are separately liquid as a high-grade public-credit asset.
Yield-spread to JGB benchmarks. Wider than Tier 1–2; spreads to JGB benchmarks in the mid-to-high single-digit basis-points range when direct-issued; joint-issuance pool prices wider than benchmark-issuer levels.
Foreign-investor participation. Minimal — domestic regional-bank, shinkin, life-insurance, and pension-fund holdings dominate.

Issuer Tier 4 — 政令指定都市 (designated cities — 20 cities)

Issuer category. 20 政令指定都市 (designated cities) — Sapporo, Sendai, Saitama, Chiba, Yokohama, Kawasaki, Sagamihara, Niigata, Shizuoka, Hamamatsu, Nagoya, Kyoto, Osaka, Sakai, Kobe, Okayama, Hiroshima, Kitakyushu, Fukuoka, Kumamoto.
Tax-base scale. Each is a major urban tax base; Yokohama, Osaka, Nagoya are the largest by population / tax base.
Issuance program. Public-offering program (the largest designated cities run material direct programs), joint-issuance pool participation, bank-underwritten private placements, JFM lending for specific public-enterprise lanes (urban water / sewerage / transit), FILP for specific-purpose long-tenor lending, sustainability-label issuance from selected cities.
Typical issue size. Public-offering tranches commonly ¥10–30 billion per series for the largest designated cities; smaller for the smaller designated cities.
Annual issuance volume. Public-offering issuance ¥100–500 billion range per city depending on size and program; combined with JFM / FILP / bank-underwritten the total annual finance need is materially larger.
JFM reliance. Moderate — designated cities draw on JFM for urban-public-enterprise lending (water / sewerage / transit) but have direct public-offering access.
FILP reliance. Moderate, depending on specific-purpose lending programs.
MIC consultation role. 協議 procedure applies; coordinated with MIC under the statutory consultation system.
MoF role. FILP allocation; capital-market coordination.
Secondary-market liquidity. Reasonable in the largest designated cities (Yokohama, Osaka, Nagoya); wider spreads and lower liquidity for smaller designated cities.
Yield-spread to JGB benchmarks. Designated-city spreads to JGB typically in the low-to-mid single-digit basis-points range for the largest cities; wider for smaller designated cities; joint-issuance pool provides comparison.
Foreign-investor participation. Modest — Yokohama, Osaka, and Nagoya bonds attract some foreign institutional interest; smaller designated-city bonds primarily domestic-held.
Specific issuer notes.
- Yokohama City (横浜市 / 横浜市債). Largest designated city by population; recurring public-offering program of substantial scale; sustainability-label issuance.
- Osaka City (大阪市 / 大阪市債). Major program; coordinates with Osaka Prefecture issuance; benefits from 2025 Osaka-Kansai Expo-related infrastructure finance.
- Nagoya City (名古屋市 / 名古屋市債). Auto-cluster industrial backdrop; recurring program; spreads typically among the tightest among designated cities.

Issuer Tier 5 — Ordinary cities / towns / villages (一般市町村)

Issuer category. Roughly 1,700 ordinary cities, towns, and villages (市町村).
Tax-base scale. Highly variable but most are small; nearly all are net recipients of 地方交付税.
Issuance program. Direct public-offering access is rare; the joint local-government bond (共同発行市場公募地方債) program exists precisely to give smaller issuers pooled market access; JFM lending is structurally dominant; FILP for specific-purpose long-tenor lending; bank-underwritten (regional bank, shinkin, credit cooperative) lending substantial.
Typical issue size. Direct public-offering rare; when joint-issuance-participating the scale is small per issuer; bank-underwritten private placements common.
Annual issuance volume. Per-issuer annual issuance often in the ¥100 million–few-¥10-billion range; total system flow material in aggregate.
JFM reliance. High to very high. Small municipalities rely heavily on JFM for long-tenor low-cost lending — this is JFM’s structural reason for existence.
FILP reliance. High, particularly for specific-purpose long-tenor lending and disaster-recovery lanes.
MIC consultation role. 協議 procedure applies; for issuers under specific fiscal-soundness conditions the statutory regime requires 許可 (authorization).
MoF role. FILP capacity allocation material; capital-market coordination minimal because direct public-offering access is rare.
Secondary-market liquidity. Direct municipal-bond liquidity essentially none in public markets; joint-issuance pool aggregates; JFM bonds for the underlying lending portfolio are separately liquid.
Yield-spread to JGB benchmarks. Mostly not directly observable as the borrowers do not access public-offering markets directly; joint-issuance pool and JFM bonds provide the effective spread reference for this tier’s public-credit funding cost.
Foreign-investor participation. Essentially none in direct municipal issuance.

Issuer Tier 6 — Special districts / public-enterprise authorities / JFM

Issuer category. Includes (a) the joint local-government corporation JFM (地方公共団体金融機構), which is not a local government but the public-credit institution lending to local governments — JFM bonds are issued by JFM itself, not by any single local government; (b) the joint-issuance pool (共同発行市場公募地方債) where multiple local governments pool issuance under joint-and-several liability; (c) public-enterprise authorities for water / sewerage / transit / hospital / port operations.
JFM bonds. Issued by the joint local-government corporation JFM; backed by the joint local-government support and statutory standing; no explicit national-government guarantee; market access AAA-equivalent.
Joint local-government bonds (共同発行市場公募地方債). Multiple local governments pool issuance; jointly-and-severally liable; mechanism designed to give smaller issuers pooled-scale market access; coordinated by Japan Local Government Bond Association.
Typical issue size. JFM senior unsecured bonds in domestic and international markets in benchmark-size tranches; joint-issuance pool in benchmark size per tranche.
Annual issuance volume. JFM domestic and international issuance program in the multi-trillion-yen-equivalent range; joint-issuance pool ¥1 trillion+ annual.
Secondary-market liquidity. JFM bonds among the most-liquid non-JGB public-credit yen-denominated assets; joint-issuance pool similarly liquid.
Yield-spread to JGB benchmarks. JFM spreads typically tight given the joint-local-government-support backing and statutory standing; joint-issuance pool spreads modestly wider than the largest named-issuer benchmarks (Tokyo Metropolitan Bond) but tighter than most individual prefecture issues.
Foreign-investor participation. Material — JFM has issued in foreign-currency markets and attracts cross-border investor interest; joint-issuance pool has more limited foreign-investor participation than JFM bonds directly.

Channel-mix structural view — five channels for local-government finance

The same underlying borrower-finance need flows through five structurally distinct channels with different supply-side counterparties:

Channel 1 — Direct public-offering (市場公募地方債)

Direct primary issuance to broad investor markets. Available structurally to Tokyo Metropolis, major prefectures, and the largest designated cities. Underwriters are securities firms (Nomura, Daiwa, SMBC Nikko, Mizuho Securities, Mitsubishi UFJ Morgan Stanley) operating in a syndicate. Investors are domestic banks, life insurers, pension funds, regional banks, Norinchukin / Shinkin Central system, foreign institutional holders (limited to benchmark issuers). Spread to JGB is the headline pricing reference; coupons set against the 10y JGB benchmark.

Channel 2 — Joint local-government bond (共同発行市場公募地方債)

Multiple local governments pool issuance under joint-and-several liability for scale, liquidity, and cost reduction. Coordinated by Japan Local Government Bond Association. Designed structurally for mid-sized prefectures and smaller designated cities that lack scale for cost-efficient standalone direct public offering. Issued in benchmark-size tranches; secondary-market liquidity good; spread to JGB modestly wider than top-tier named-issuer benchmarks.

Channel 3 — Bank-underwritten / private placement (銀行等引受 / 私募債)

Direct bank lending or private-placement bonds underwritten primarily by regional banks and shinkin. Available to all issuer tiers but structurally important for mid- and small-prefecture issuers, ordinary cities, towns, villages. Pricing reflects bilateral negotiation; secondary-market liquidity essentially none. Investor base is the originating bank and a small set of relationship financial institutions.

Channel 4 — JFM lending

The joint local-government corporation JFM lends against local-government obligations using funding raised by JFM’s own bond issuance (JFM bonds in domestic and international markets). Structurally important for all tiers but especially for ordinary cities, towns, and villages that cannot tap public-offering markets efficiently. JFM’s value proposition is long tenor (20–30 years) + low cost + scale — none of which any single small municipality can achieve standalone. The borrower-side pricing pass-through reflects JFM’s own AAA-equivalent bond-market spread plus a thin spread for JFM’s operating costs.

Channel 5 — FILP / 財政融資資金 (Fiscal Loan Funds)

MoF-managed national-government direct-lending pool that supplies long-term low-cost loans to local governments. The funding source is FILP bonds (財政投融資特別会計国債) issued by MoF; the lending channel routes through the FILP system to local-government borrowers for specific-purpose long-tenor lending (water, sewerage, transit, public housing, schools, disaster recovery). FILP reliance is highest for the smallest municipalities and for specific-purpose long-tenor lending. Pricing is set administratively rather than market-determined.

Issuer-credit logic — five-step framework

Reading a Japanese local-government issuer’s credit:

Issuer type. Tokyo Metropolis / 都道府県 / 政令指定都市 / 一般市町村 / joint issuance pool / JFM / public-enterprise — first axis controls almost every other field.
Use of proceeds. Infrastructure / public enterprise (water, sewerage, transit, hospital, port, gas, electricity) / refinancing / disaster recovery / other statutorily-permitted purposes. Local Finance Act constraint.
Revenue base. Local taxes + 地方交付税 (LAT) + national treasury disbursements + fees and charges. LAT status (不交付団体 vs receiving) is a critical credit lens.
Fiscal-soundness indicators. Real debt service ratio (実質公債費比率), future-burden ratio (将来負担比率), real-deficit ratio, consolidated real-deficit ratio, financial-capability index (財政力指数). Statutory thresholds trigger corrective regimes (財政健全化団体 / 財政再生団体).
Market access. Direct public-offering / joint-issuance / JFM-dependent / FILP-dependent / bank-underwritten-dependent. Channel mix determines effective funding cost and the role of public-credit institutions.

Investor-base structural view

Local-government bond demand is concentrated in domestic institutional investors with limited foreign-investor participation outside the largest named benchmark issuers:

Domestic banks (banking sector). Megabanks, regional banks, second-regional banks, shinkin, credit cooperatives. Regional banks hold material local-bond exposure as part of their portfolio diversification away from JGBs. The banking-domain holder base is the largest single investor cohort.
Life insurance and pension funds. Long-tenor demand for high-grade yen-denominated public credit; large institutional holders of long-tenor public-offering local bonds and JFM bonds.
Public pension and GPIF / public funds. Hold large allocations to JGBs and selectively to JFM bonds and benchmark local bonds.
Cooperative-banking apex institutions. Norinchukin, Shinkin Central, 労金連, 全信組連 hold material public-credit yen exposure including local bonds and JFM bonds.
Foreign institutional holders. Concentrated on Tokyo Metropolitan Bond, JFM bonds (including foreign-currency-denominated issuance), and selectively on the largest named-prefecture and designated-city issuers (Osaka, Aichi, Kanagawa, Yokohama, Nagoya). Small-issuer bonds and the bulk of joint-issuance bonds are essentially domestically-held.
Retail investors. Tokyo Metropolitan Government and selected other issuers run retail-targeted bond series targeted at residents. The retail share of total local-bond issuance is modest but structurally meaningful for issuer-name recognition.

The investor-base concentration in domestic institutional holders, plus the demographic / tax-base structure of the Japanese local-government sector, means that local-bond market dynamics are closely coupled to BoJ monetary policy, JGB market dynamics, and Japanese money market conditions — see JGB repo market for the collateral side.

How to read this matrix

This matrix is a public-surface tool. It does not provide investment recommendations, does not estimate issuer-specific credit risk, and does not predict spread movements. It exists so that a local government bond market reference can be classified consistently by issuer tier and channel before the deal / portfolio / investor question gets asked.

When reading any single local-government bond reference:

Start with the issuer category column — that determines almost every other field. Tokyo Metropolis is structurally different from a 不交付団体 perspective; designated cities are different from ordinary cities; JFM bonds are not local-government bonds at all.
Check the LAT status column. 不交付団体 vs LAT-receiving status affects credit logic.
Check the JFM / FILP / bank-underwritten share columns. Channel mix determines effective funding cost and the role of public-credit institutions.
Use the MIC role column to read whether 協議 (consultation) or 許可 (authorization) regime applies — the regime is tighter for fiscally-stressed issuers.
Check the secondary-market liquidity and yield-spread columns together. Liquidity dries up faster than spread widens for non-benchmark issuers under stress.

Boundary cases / 政策金融 reform context

Not JGBs. Local-government bonds are not sovereign debt. Repayment ultimately depends on the issuer’s tax base + 地方交付税 + statutory support, not on the national-government balance sheet. The 地方交付税 fiscal-equalization layer is material for credit perception but does not create an explicit national-government guarantee.
Not JFM bonds. JFM bonds are issued by the joint local-government corporation, not by any local government. They form a separate public-credit asset class backed by joint local-government support and statutory standing, not by any single issuer’s tax base.
Not joint-issuance bonds. The joint local-government bond (共同発行市場公募地方債) program pools issuance from multiple local governments under joint-and-several liability; this is distinct from JFM bonds (which are JFM-issued) and distinct from individual-issuer public-offering bonds.
Not unrestricted spending. Local-government bond issuance is permitted only for statutorily-defined purposes under the Local Finance Act (地方財政法) — infrastructure, public enterprises (water, transport, hospitals), refinancing, disaster recovery, and other defined uses. The use-of-proceeds discipline is statutory, not contractual.
Public-enterprise bonds vs general local-government bonds. Public-enterprise bonds (公営企業債) are issued for water / sewerage / transit / hospital / port-operation public enterprises and have distinct repayment-source logic vs general local-government bonds, even when the issuing local government is the same.
政策金融 reform context. The 2008 reform that created JFM from 公営企業金融公庫 explicitly removed national-government equity from the joint local-government corporation; this is the structural answer to the long-standing question of how to provide low-cost long-tenor lending to local governments without putting the entire credit risk on the national-government balance sheet. The post-2008 design is unusual internationally — closer to Scandinavian municipal-funding agencies (Kommuninvest, KommuneKredit) than to US municipal-bond market structure.
Statutory fiscal-soundness regime. The Local Government Financial Soundness Act (地方公共団体の財政の健全化に関する法律) sets statutory indicators (real debt service ratio 実質公債費比率, future-burden ratio 将来負担比率, real deficit ratio, consolidated real deficit ratio) — crossing thresholds triggers fiscal-soundness corrective regimes, which in turn shift bond-issuance from 協議 to 許可.
Disaster-recovery bonds. Specific disaster-recovery bonds issued after East Japan (2011), Kumamoto (2016), West Japan (2018), Noto (2024) carry distinctive program logic — typically supported by national-government supplementary budget programs through LAT mechanism and through JFM disaster-recovery lending lanes.
Pandemic-era issuance. 2020–2022 Covid-era municipal finance generated material additional issuance and JFM lending, with national-government supplementary-budget support flowing through LAT.
