Company history

In April 1967 Fukuda Yoshitaka began lending money in Kyoto under the shop name Marutaka — a sole proprietorship with three branches in Kyushu and one at home. Japan’s consumer-finance industry was then in its growth phase, taking over the small unsecured lending that pawnshops and instalment houses had done, and the field was already claimed: Takefuji, Promise and Acom were building national chains out of Tokyo and Osaka. A Kyoto independent was, by definition, the outsider.

The company was formalized in stages. Marutaka Co., Ltd. was incorporated in Kyoto in February 1978 with capital of $44,776 (¥9m); in May 1982 it absorbed three affiliated lenders, raised capital to $2M (¥500m) and took the name Aiful — the moment a local shop acquired a balance sheet fit for national expansion, and the moment it took up position as the fourth force behind the big three. When the 貸金業規制法 (Money Lending Business Act) came into force in March 1984, Aiful registered as a licensed lender, which separated it from the unregulated street lenders and let it advertise on television while opening branches nationwide.

The 1990s stagnation did the rest. As bank credit narrowed, demand for small unsecured loans widened among both households and micro-businesses, and the loan books of the big four swelled. But growing a lending book means funding it, and a family-owned outsider could not fund it from retained earnings. In July 1997 Aiful registered its shares over the counter with the Japan Securities Dealers Association — its first access to the capital market, and the hinge on which everything after it turns.

The listing ladder was climbed fast. Aiful joined the second sections of the Tokyo and Osaka exchanges and the Kyoto exchange in October 1998, and moved up to the first sections in March 2000, taking a seat alongside Takefuji, Promise and Acom. What the promotion bought was not prestige but funding capacity, and Aiful spent it immediately.

From 2000 the strategy turned to acquisition. Subsidiaries took over the lending books of Happy Credit and Sky and brought in Shinwa; in January 2001 Aiful set up Businext, a small-business lender, as a joint venture with Sumitomo Trust; in March 2001 it bought Life, then in court-supervised reorganization, and with it a credit-card business. Cityz, City Green, Kokusai Capital, Wide, TCM and Passkey followed between 2002 and 2005.

By the mid-2000s the group looked like a financial conglomerate — consumer lending, business lending, cards and debt collection — assembled in five years and directed personally by its founder. Among the big four, Aiful was the most acquisitive, and the least insulated: the others had, or would soon have, banks behind them. Aiful had a share price and a loan book.

In January 2006 the Supreme Court effectively ruled that interest collected above the Interest Rate Restriction Act ceiling — the so-called grey zone — had to be refunded. In December the Money Lending Business Act was amended, cutting the rate cap and phasing in, through 2010, a limit on lending to one-third of a borrower’s annual income. Together the two turned twenty years of accumulated interest income into a liability and legally shrank the source of future profit. Refund claims exploded, provisions ballooned, and the industry’s outstanding loans fell from a 2006 peak of roughly $103.2B (¥12tn) to about $30.7B (¥3tn) — a market cut to a quarter of itself.

In September 2009 Aiful sold four subsidiaries and, the same month, filed for business-revitalization ADR, Japan’s out-of-court workout procedure. The alternatives were both worse in the same way. Court-supervised reorganization would have cut the debt but cost the listing and the owners’ control; a megabank rescue would have thickened the capital but ended independent, founder-led management. ADR bought time from the lenders while leaving both intact.

The rest of the big four went the other ways. Takefuji filed for corporate reorganization in September 2010 and failed; Acom moved under Mitsubishi UFJ from 2008; Promise became SMBC Consumer Finance under Sumitomo Mitsui in 2012. Aiful alone came through as an independent listed company. It paid for that with its size — headcount and branches cut by nearly half — and with a long cleanup: the Osaka listing was dropped in 2010, Life Card was spun out as a separate company in July 2010, and in 2011 four group companies were folded back into the parent.

Recovery was slow and interrupted. Consolidated net profit reached $284.5M (¥23bn) in the year to March 2013 and $311.5M (¥30bn) the year after, only for an additional provision against refund claims to push the company back into a loss of about $344.9M (¥37bn) in the year to March 2015. The grey zone kept billing the company for more than a decade after the ruling.

What changed structurally was the shape of the earnings. Rather than rebuild as a single-product lender, Aiful pushed resources into Life Card, the card and credit-guarantee company created in 2010, which by the year to March 2015 was contributing about a third of group revenue; and in 2013 it bought out its partners in Businext to own the small-business lender outright. Consumer loans, cards and business loans became three layers instead of one. In December 2014 the group also went abroad, forming AIRA & AIFUL in Thailand with a local partner — a modest hedge against a domestic market that had shrunk by three-quarters, and still only a few percent of consolidated revenue by the end of the decade.

In June 2020 the founder handed over the presidency to his eldest son, Fukuda Mitsuhide — the first change of leadership in the company’s 53 years, and the latest generational handover among the big four. Fukuda Yoshitaka, president since founding the business in 1967, moved to representative chairman and remains there. The new president, who joined in 2011 after Daiwa Securities, set his agenda immediately: bring the core systems in-house, build engineers rather than rent them, and remake a consumer lender as a technology company.

From July 2020 the group renamed itself in bulk. Businext became Aiful Business Finance, Astry Debt Collection became AG Debt Collection, Life Guarantee became Aiful Guarantee, and the AG prefix spread across the group through the first half of the decade. Behind the naming came new lines of business: AG Mirai Barai for buy-now-pay-later in 2020, a medical-receivables lender the same year, the pet insurer FPC acquired in 2023 and consolidated in 2024, and the prepaid e-money issuer BitCash in 2024. Guarantee and payments were merged into AG Payment Service in 2024; SES staffing companies were gathered under AG Solution Technology in 2025. In five years the group went from three businesses to nine.

The numbers improved with the sprawl. Consolidated operating revenue set records three years running — about $1.0B (¥132bn), $1.0B (¥144bn) and $1.1B (¥163bn) — with net profit above $132M (¥20bn) each year. But this is still lending: total assets rose from roughly $8.3B (¥665bn) in the year to March 2012 to about $9.6B (¥1.45tn), and interest-bearing debt grew about 2.5-fold over the decade. Credit growth and borrowing move together, as they always have in this trade.

The last step was structural. In May 2025 the board resolved on a sole share transfer; Aiful Corporation (8515) was to leave the Tokyo Stock Exchange in March 2026 and Muninova Holdings (547A) to list on the Prime Market in April 2026 as its wholly owning parent. The point was division of labour — capital allocation and M&A strategy at the holding company, consumer lending on the ground at Aiful — for a group whose businesses had become too unlike each other to run from one head office. It also ended the listing of a name carried since 1982. Fukuda Mitsuhide leads the new company; his father remains chairman; and of the four lenders the 1990s called the big four, the one still standing on its own is now trading under a different name.
