Employees at a Japanese housing manufacturer filed fraudulent fire insurance claims using photographs recycled from previous incidents – and the nonlife insurers involved say the problem extends well beyond the single branch the company had identified.
Tama Home Co., a custom homebuilder that also operates as a licensed insurance agent selling fire and other products, initially attributed the misconduct to its branch in Takamatsu, Kagawa Prefecture, in western Japan. Nonlife insurers conducting their own review found otherwise, according to Jiji Press. The alleged fraud spans several hundred cases and is estimated to total several tens of millions of yen. Some claims also involved inflated amounts.
An unidentified company spokesperson confirmed that an internal investigation, led by headquarters, is now under way across all 236 of the company’s branches.

The fraud involved submitting photographs from past legitimate claims as evidence for separate, new payouts. The technique exploited gaps in document verification at the claims stage – a weakness that becomes structurally harder to audit when the same entity manages both the construction work and the insurance placement.
Tama Home’s dual role sits at the centre of this case. Under Japan’s Insurance Business Act, non-insurance companies can register as agents and place cover on behalf of clients. Tama Home did exactly that, acting as an intermediary for fire and other policies while also carrying out the renovation work those policies were written to cover. That arrangement gave employees access to both the claims documentation and the physical sites –the combination the alleged scheme appears to have exploited.
The nonlife insurers named in Jiji Press’s reporting have called for a third-party body to conduct its own review, signalling their view that an internal probe led by the same headquarters overseeing the implicated branches is insufficient.
Japan’s nonlife market has been here before. The used car dealer Bigmotor Co. lost its insurance agent registration in late 2023 after the Financial Services Agency (FSA) found that employees had deliberately damaged customers’ vehicles to generate inflated repair claims. Bigmotor, like Tama Home, operated simultaneously as a service provider and a licensed insurance agent. The FSA subsequently issued business improvement orders against nonlife insurers that had been routing business through Bigmotor, finding they had continued the relationship despite evidence of fraud.
The parallel drew direct comment from Japan’s Minister of Finance and Minister of State for Financial Services, Katayama Satsuki, at a press conference in July 2026. “The actual state of insurance agents was also an issue in the BIGMOTOR case,” Katayama said, adding that the FSA had decided to conduct a survey of the actual situation of agents that also engage in other businesses. She distinguished between large-scale operators – those with insurance-related revenue running into billions of yen – and smaller operators that mainly provide their primary services while carrying an insurer’s banner, noting that compliance obligations under the amended Insurance Business Act should be scaled accordingly.

The Insurance Business Act was amended by Japan’s Diet in May 2025, with the revised act entering into force in June 2026, specifically to address misconduct by agents operating in corporate settings. According to the FSA’s Annual Report on Insurance Monitoring published in August 2026, the regulator noted that the nonlife sector is expected to continue advancing reforms in response to those legislative changes and that it will take supervisory action as necessary.
That reform backdrop directly frames the Tama Home case. According to L.E.K. Consulting’s analysis of Japan’s insurance distribution market published in May 2026, approximately 9,530 entities are recognised as in-house agencies by the four major nonlife insurers – a figure drawn from a Financial Services Agency working group survey – indicating how widespread the dual-role model remains even as regulatory expectations tighten around it.
For insurance professionals with Japan exposure, the case raises a concrete question: when a corporate entity operates as both a service provider and an insurance agent, what level of ongoing oversight do the sponsoring nonlife insurers perform?
Under Japan’s regulatory framework, the sponsoring insurer bears legal responsibility for the conduct of its appointed agents. The FSA’s 2026 supervisory guidelines – revised in parallel with the amended Insurance Business Act – require insurers to implement enhanced due diligence and periodic compliance reviews across their agent networks. The Tama Home case will test how thoroughly those obligations were being met by the nonlife companies that placed business through its agency network.
Neither the FSA nor the nonlife insurers involved have publicly confirmed whether any supervisory action against Tama Home as a registered agent is under consideration.
