TL;DR

Kampo Life is one of the largest life-insurance balance sheets in Japan by reserve and asset scale, originated as the postal-savings-era national insurance scheme (郵便貯金 / 簡易保険 / “Kanpo”) and now a publicly listed subsidiary inside the Japan Post Holdings (6178) group, which also owns Japan Post Bank (7182) and Japan Post Co. The franchise rests on three pillars that no other life big-four insurer shares: the postal-channel distribution agreement with Japan Post Co.’s branch network, a structurally large in-force book of legacy 簡易保険 (kanpo) policies inherited from the privatization, and a long-duration yen-liability balance sheet running ALM under the Japan life ALM dynamics in the low-rate / post-zero-rate era. The 2019 fraudulent-sales scandal (不適正募集問題) — improper conversion, dual-billing, and suitability failures across the postal sales force — was the defining recent governance event and reshaped distribution, supervision, and the product mix. The FSA / MIC business-improvement orders, the voluntary sales suspension, and the subsequent rebuild of sales infrastructure mean Kampo’s post-2019 trajectory is structurally different from its pre-2019 trajectory even though the balance-sheet scale remains comparable to the largest private mutual life insurers.

Wiki route

This page sits under insurance INDEX and is the postal-life counterpart to the Japan life big four and its overlay comparison matrix. Read it together with the Japan life ALM overview for the asset-liability problem, mutual vs stock for the corporate-form contrast (Kampo is listed, like Dai-ichi HD, but the parent and ultimate owner is JP Holdings, partly state-related), economic-value-based solvency and ESR for the headline capital metric, the life insurance channel mix for the postal-channel placement, and the agency and brokerage Japan landscape for the post-2019 channel rebuild. The entity anchors are Kampo Life / 7181 and Japan Post Holdings / 6178. For the supervisor map see the FSA and the Ministry of Internal Affairs and Communications (MIC / 総務省) postal-business supervision.

Identity and group structure

Kampo Life is the formal corporate successor to the pre-privatization 簡易保険 (kanpo) business of Japan Post, established as a stock-form life insurer during the 2007 postal privatization and listed on the Tokyo Stock Exchange in 2015 alongside Japan Post Holdings and Japan Post Bank. The group hierarchy is:

The listing of all three operating entities is itself unusual: a holdco and two of its operating subsidiaries are all separately listed, which means Kampo carries holdco-shareholder governance from JP Holdings, public-market governance from its own listing, and group-level capital and group-business considerations from the JP Holdings level. Capital actions (including JP Holdings divestment of Kampo / Japan Post Bank shares) are an ongoing structural overhang.

Balance sheet and scale

Kampo’s general-account assets place it in the same scale bracket as the largest life big-four mutuals. The reserve and asset profile is dominated by:

  • JGBs — historically a very large share of total assets, reflecting the conservative public-sector heritage and the long-duration yen liability book; the JGB allocation share has gradually declined as the insurer extended into other asset classes.
  • Domestic credit, foreign-currency bonds, equities, and alternatives — diversification away from the JGB-dominant legacy.
  • Hedged foreign-bond book — the same ALM problem as the private big-four; see Japan life insurance ALM overview for the framework.
  • Legacy kanpo block — the pre-privatization 簡易保険 policies are accounted for under a separate management framework (managed under contract with the Management Organization for Postal Savings and Postal Life Insurance, 郵便貯金・簡易生命保険管理・郵便局ネットワーク支援機構) and overlay the new post-2007 Kampo block.

The dual structure — legacy kanpo + new Kampo — is the key feature that distinguishes Kampo’s balance sheet from the private big-four. Asset-class allocation and ALM are reported on a consolidated basis but the underlying liability structure has two distinct vintages.

Distribution: postal channel

The defining distribution feature is the postal-channel agreement with Japan Post Co. — Kampo policies are sold through the ~20,000-branch post-office network (the largest physical retail footprint in Japan) and through directly-employed Kampo sales staff. There is no tied female sales-force comparable to Nippon Life‘s Nissay Lady model; instead the post-office counter staff plus Kampo sales staff form the dominant channel.

Other channels — bancassurance, independent agency, internet-direct — exist but are much smaller. The reliance on the postal channel is both the franchise’s structural advantage (a customer base and physical-network reach no competitor can match) and the source of the 2019 scandal (the same network created sales-incentive pressure that drove the misconduct).

See the bancassurance economics Japan page and the life insurance channel mix for the broader channel context.

The 2019 fraudulent-sales scandal

The 2019 不適正募集問題 / “improper-sales” scandal is the defining recent governance event:

  • What happened. Internal and external reviews surfaced widespread improper-sales practices in the postal channel: conversion misconduct (existing policies surrendered then re-issued without proper suitability assessment), dual-billing (customer paying both old and new policy premiums during transition), suitability failures (sales to elderly / vulnerable customers without adequate explanation), and incentive-driven volume push by both Kampo sales staff and post-office counter staff.
  • Scale. Tens of thousands of policies were identified as potentially problematic in the initial investigation; the figure expanded over subsequent reviews.
  • Regulatory response. The FSA and the MIC issued business-improvement orders to Kampo and Japan Post Co. A voluntary suspension of active sales solicitation followed, with phased resumption under upgraded controls.
  • Internal response. Sales-force restructuring, suitability-control rebuild, board / management changes at Kampo, JP Holdings, and Japan Post Co. Renewal of the postal-channel agency contract with strengthened conduct guardrails.
  • Customer remediation. A multi-year customer-contact and remediation program covering identified policies and an extended review universe.
  • Aftermath. The post-2020 trajectory is a slow rebuild rather than a return to pre-2019 volumes. Net new-policy issuance contracted materially in the immediate post-scandal period and the in-force book has been managed under run-off-adjacent dynamics on the legacy block.

The scandal is publicly documented through FSA / MIC orders and Kampo / JP Holdings IR materials. Treat any “Kampo strategy” framing pre-2019 and post-2019 as structurally different periods.

ALM in the low-rate era

The ALM problem at Kampo is conceptually the same as at the private big-four mutuals: long-duration yen liabilities, structurally low JGB yields, foreign-bond reach for yield, hedge cost on the foreign-bond book, equity-allocation reduction in line with the broader cross-shareholding wind-down. The features that distinguish Kampo are:

  • Higher historical JGB share. Kampo’s legacy allocation skew is more JGB-heavy than the private big-four, reflecting its public-sector origin; diversification has progressed but the starting point was different.
  • Smaller foreign-life affiliate footprint. Unlike Dai-ichi Life Holdings with Protective Life and TAL, Kampo does not have a comparable overseas-life acquisition portfolio. Diversification has been primarily asset-side rather than business-side.
  • Capital governance under dual listing. Kampo’s capital policy (ESR target, shareholder dividend, JP Holdings parent-shareholder dynamics) is governed by both its own listed-company framework and the JP Holdings group framework.
  • Legacy-block run-off dynamics. The pre-privatization kanpo block runs off over time; the new-policy block has to compensate. Post-2019, new-policy issuance is materially reduced versus the pre-scandal trajectory.

ESR is published under the FSA economic-value-based solvency regime from April 2025 onward, in the same format as the private big-four. See ESR for the ratio definition.

Decision use

Use this page when:

  • Reading Kampo’s annual report, IR materials, or ESR disclosure with the institutional context in mind.
  • Sizing the Japan life-insurance sector and including Kampo alongside the big-four mutuals plus Dai-ichi HD.
  • Analysing the postal-channel distribution model versus tied / bancassurance / agency models.
  • Tracing the structural consequences of the 2019 scandal — sales-force rebuild, suitability controls, run-off-adjacent dynamics on the new-policy book.
  • Modelling JP Holdings group capital allocation and the Kampo / Japan Post Bank divestment overhang.
  • Cross-referencing with the Kampo Life entity entry and JP Holdings for share-ownership and listing detail.

Boundary cases / caveats

  • Numbers are conceptual. Asset / reserve / ESR figures are date-sensitive; consult Kampo IR materials for current readings.
  • Legacy kanpo vs new Kampo. The pre-privatization block has a different accounting / management framework. Don’t conflate the two.
  • Postal-channel agency contract. The agreement between Kampo and Japan Post Co. is a commercial contract subject to renewal; the structural channel logic should not be assumed permanent in current form.
  • JP Holdings capital policy. JP Holdings (the parent) has its own capital and dividend dynamics and ongoing divestment of Kampo / Japan Post Bank shares is a structural feature, not a one-off.
  • Government ownership. A residual government holding in JP Holdings shapes governance expectations; Kampo is not directly state-owned but the chain runs back to a state stake.
  • Pre-2019 vs post-2019. Treat the scandal as a structural break. Trend extrapolation across the break is misleading.
