TL;DR

A major Kyoto-born consumer-finance company. In 1967-04 Yoshitaka Fukuda founded it as the sole proprietorship “Marusan” in Kyoto, renaming it “Aiful” in 1978 . Its business is anchored on unsecured personal loans (card loans) + credit cards (the Life Card subsidiary) + business loans. Among the “3 major consumer-finance firms” alongside Acom (within mufg) and Promise (within smfg), it is the only major independent one not belonging to a megabank group ★. The grey-zone-interest / overpaid-interest refund problem of 2006-2010 caused a management crisis → it was rebuilt via business-rehabilitation ADR. Listed on the Tokyo Stock Exchange PRIME 8515 .

Unsecured personal loans	Aiful / Carent 2 brands	Flagship; card-loan-centered, fully online / automated contract machines
Credit cards	Life Card (made a wholly owned subsidiary in 2017 )	Master / VISA / JCB partnerships; strong with younger / light-user segments
Business loans	Aiful Business Finance	For SMEs / sole proprietors
Real-estate-secured loans	Carent / proper	A complement anchored on secured loans

3. History

Year/month	Event
1967-04	Yoshitaka Fukuda founds the sole proprietorship “Marusan” in Kyoto ★
1978	Incorporated as a stock company; trade name changed to “Aiful”
1980s	Nationwide expansion; channel expansion centered on automated contract machines
1998	Over-the-counter registration with the Japan Securities Dealers Association (JASDAQ listing)
2000-04	Listed on the Tokyo Stock Exchange First Section
2003	Peak of the “consumer-loan 4 giants” era of Promise, Acom, Takefuji, and Aiful
2006-01-13	Supreme Court ruling effectively made “grey-zone interest” illegal ★ → a flood of overpaid-interest claims
2006-12	Enactment of the amended Money Lending Business Act (cap-rate reduction / introduction of total-volume regulation; enforced 2010-06)
2008-04	FSA business-improvement order (problems with collection methods / firm-wide business-suspension disposition) ★
2009-09	Filed for business-rehabilitation ADR → third-party allotment capital increase / debt restructuring with the bank syndicate
2010-06	Full enforcement of the amended Money Lending Business Act (cap rate 20% / total-volume regulation at annual income 1/3)
2010-2015	Management hardship from overpaid-interest refunds; industry-wide, Takefuji went into corporate reorganization while Aiful continued ADR rehabilitation
2014〜	Business-resumption / earnings-recovery phase
2017	Made Life Card a wholly owned subsidiary ★
2018-2019	Performance recovery / entrenchment of profitability
2022-04	TSE market-segment review → TSE PRIME 8515
2024〜	Medium-term management plan (profitability-entrenchment phase, AI credit / fully-online expansion)

Impact of the overpaid-interest problem (2006〜) ★

Supreme Court ruling (2006-01-13): largely negated the “deemed repayment” provision of the Money Lending Business Act → amounts exceeding the Interest Rate Restriction Act (cap 15-20%) became subject to a refund obligation as unjust enrichment
2006 amended Money Lending Business Act: lowered the cap rate from 29.2% to 20% and introduced total-volume regulation (annual income 1/3)
Overpaid-interest refunds: industry-wide refunds on the scale of several trillion yen; Takefuji filed for corporate reorganization in 2010-09 , while Aiful was rebuilt via business-rehabilitation ADR
2008-04 business-improvement order: a firm-wide business-suspension disposition for inappropriate collection methods → a long period for credit recovery

Strategy for maintaining independence ★

As a major independent firm not belonging to a megabank group:

Continued management centered on the founding Fukuda family
In-house credit data + AI scoring so as not to rely on a bank parent’s credit support
Carent / Life Card to secure revenue axes beyond consumer finance

Competitive structure

Competitor	Affiliation	Difference from Aiful
Acom	mufg-affiliated (equity method 39.6%)	Ahead via the parent’s bank ATMs / customer referrals; overseas expansion (e.g., Thailand’s Easy Buy)
[[consumer-finance/smbc-consumer-finance	プロミス（SMBCコンシューマーファイナンス）]]	smfg 100% wholly owned subsidiary
Rakuten Card / PayPay Card	rakuten-fg / paypay-fg	Integrated with e-commerce / payment platforms; ahead with younger segments
Bank card loans	All megabanks / regional banks	Banks’ directly operated low-rate card loans have become substitute products
orico / credit-saison / jaccs	Credit-sales affiliated	A different per-item-installment axis; adjacent to consumer finance

Medium-term strategy (publicly stated direction)

Deepening of the 3 -brand structure (Aiful / Carent / Life Card)
AI credit scoring: improving the precision of fully-online / instant screening
Profitability-entrenchment phase: reducing overpaid-interest refund provisions, securing the profitability of core businesses
Overseas (ASEAN) expansion: small-lot personal finance via local entities in Thailand, Indonesia, etc.
Expansion of the bank-guarantee business: securing stable revenue as a behind-the-scenes player for bank card loans

B2C branding

The “Wan!” commercials maintained brand awareness over a long period (TV commercials featuring a Chihuahua were a symbol of the 2000 年 era)
The “Aiful” brand = consumer finance; “Carent” and “Life Card” secure separate brand layers

5. Regulation / policy

Competent authority: Financial Services Agency (FSA)
Registration: a registered money lender under the Money Lending Business Act
Industry body: member of the Japan Financial Services Association (JFSA)
Main regulations:
- Money Lending Business Act: cap rate 20% (10 万円 or below is 20%, 10〜100 万円 is 18%, above 100 万円 is 15%)
- Total-volume regulation: an individual’s total borrowing is capped at 1 -3 th of annual income (fully enforced 2010-06 )
- Installment Sales Act: a comprehensive credit-purchase intermediary for the Life Card portion
- Act on the Protection of Personal Information: handling of credit information
Recent policy issues:
- 2024〜 accountability / anti-discrimination for AI credit
- Overpaid-interest claims are on a declining trend but have not completely disappeared
- The “de facto total-volume-regulation excess” problem of bank card loans (industry self-regulation)
