Japan Weighs Expanding Mutual Fund Investment in Unlisted Companies

Japan’s Financial Services Agency (FSA) is reviewing a proposal to allow mutual funds to increase their investments in unlisted companies, a move aimed at broadening access to private capital for startups and growth-oriented businesses while expanding investment options for retail investors.

The potential policy shift, currently under discussion within Japan’s financial regulatory framework, would relax existing limits that restrict mutual funds from allocating more than a small portion of their assets to non-publicly traded equities. If implemented, it could channel significant institutional capital toward Japan’s growing venture capital and private equity ecosystem.

Under current regulations, mutual funds in Japan are generally permitted to invest in unlisted stocks only up to 5% of their total assets, a cap designed to manage risk exposure to less liquid and less transparent investments. The FSA’s review considers raising this threshold, potentially to 10% or higher, depending on fund type and risk management safeguards.

Officials say the change would support Japan’s broader economic strategy of fostering innovation and entrepreneurship, particularly in sectors such as artificial intelligence, biotechnology, and green technology, where many high-potential firms remain privately held longer due to delayed public listings or preference for private funding.

The proposal aligns with efforts to strengthen Japan’s asset management industry, which has been encouraged to play a more active role in domestic capital formation. Policymakers view mutual funds as a conduit through which retail savings can be redirected toward productive private investment, thereby reducing reliance on bank financing and enhancing market diversity.

Industry representatives have expressed cautious support, noting that while mutual funds could bring valuable scale and discipline to private markets, any expansion must be accompanied by robust due diligence requirements, valuation standards, and investor protection measures to address concerns about opacity and liquidity risk in unlisted securities.

Japan’s mutual fund sector manages over ¥100 trillion in assets, according to the Investment Trusts Association, Japan. Even a modest reallocation toward unlisted equities could represent tens of billions of yen in new annual capital availability for private firms, particularly benefiting early- and growth-stage companies that face funding gaps between angel investment and later-stage venture rounds.

Regulators are studying models from other markets, including the United States and Europe, where mutual funds and exchange-traded funds (ETFs) have greater flexibility to invest in private assets under specific conditions, such as qualified investor limits, lock-up periods, or specialized fund structures designed to handle illiquidity.

The FSA has not set a timeline for a final decision, but officials indicated that consultations with asset managers, legal experts, and investor advocacy groups are ongoing. Any regulatory change would likely be phased in, with initial allowances possibly limited to certain fund categories, such as those targeting institutional or sophisticated retail investors.

If approved, the reform would mark a notable shift in Japan’s traditionally conservative approach to mutual fund regulation, reflecting a growing recognition that private markets play an increasingly vital role in innovation-driven economies and that public investment vehicles can help bridge the gap between savings and entrepreneurial finance.
