Japan’s first Bitcoin ETF could arrive by 2028 with ¥3T inflows

Japan could launch its first Bitcoin exchange-traded fund as early as 2028 as regulators prepare rules that would allow investment trusts and ETFs to hold crypto assets directly.

A July 23 Nikkei report said the Financial Services Agency plans to revise investment-fund rules after lawmakers approved amendments that bring crypto assets under the Financial Instruments and Exchange Act framework. The change moves Japan toward treating crypto as a financial investment product rather than regulating it mainly as a payment asset.

Meanwhile, the legal change does not mean a Bitcoin ETF can launch immediately. Japan still needs detailed rules and changes to its investment-trust framework before fund managers can offer products that hold crypto as a primary investment target. 

The FSA’s materials confirm that crypto regulation is moving from the Payment Services Act into the Financial Instruments and Exchange Act, alongside new disclosure and market conduct requirements.

As crypto.news reported on July 15, Japan has passed legislation that creates a pathway for domestic crypto ETFs, although individual products will still require regulatory approval. An earlier report said Japan Exchange Group was considering listings as early as 2027, while the latest Nikkei report points to 2028 as a possible launch date. 

JPX chief executive Hiroki Yamamichi previously said an ETF “can be done anytime once the legal framework is in place and the tax treatment is clarified.”

Financial groups prepare for Bitcoin ETFs

Several of Japan’s largest financial firms are studying products that could enter the market once regulators complete the rules. As previously reported, SBI Securities and Rakuten Securities are preparing crypto investment trusts through their own groups. Nomura, Daiwa, SMBC-linked firms and Asset Management One are also examining possible products.

The planned market could extend beyond Bitcoin ETFs. SBI Global Asset Management has considered funds focused on liquid crypto assets such as Bitcoin and Ethereum. Meanwhile, Osaka Exchange has discussed launching Bitcoin futures in 2028 if spot ETFs become legal. These plans show that traditional financial firms are preparing products before regulators complete the final framework.

Institutional interest is also rising. Nomura Holdings’ 2026 survey found that 79% of respondents who were considering crypto investment over the next three years planned to invest. Among them, 60% expected to allocate between 2% and less than 5% of their portfolios. The survey also found that 65% viewed crypto assets as a way to diversify their investments.

Retail investors could become the main source of demand

Japan’s Bitcoin ETF market may develop differently from the U.S. market, where institutional investors have become major participants in spot Bitcoin ETFs. Japan has a smaller pool of institutions making large crypto allocations, while households continue to keep a large share of their financial wealth in cash and deposits. Bank of Japan data has placed the cash and deposit share at around half of household financial assets.

That structure could make individual investors a major source of demand. The July 23 Nikkei report estimated that Japanese Bitcoin ETFs could attract as much as ¥3 trillion by fiscal 2028. 

The FSA has also reported more than 14 million domestic crypto accounts, while about 70% of account holders earn less than ¥7 million annually. A regulated ETF could allow investors to gain Bitcoin exposure through securities accounts without directly managing crypto wallets.

The same retail focus is visible among financial groups preparing new products. Rakuten plans to make crypto investment trusts available through smartphone services, while other brokerages are studying products that could fit into existing investment platforms used by individual customers.

Pension interest adds another route for crypto exposure

Institutional adoption remains limited, but some Japanese pension managers have begun testing small crypto allocations. The National Business Pension Fund in Okayama, which represents about 1,200 small and medium-sized businesses, plans to allocate about 1% of its assets to crypto-related funds during fiscal 2026.

Aiyu Kiguchi, the fund’s executive director of investment management, explained the diversification strategy by saying, “It’s because its price movements have a low correlation with the U.S. dollar.” The fund manages about ¥21.5 billion and plans to gain exposure through funds managed by major overseas hedge funds rather than buying crypto assets directly.

The move also comes as broader investor interest grows. Nomura’s survey found stronger demand for crypto as a diversification tool, while financial firms continue preparing investment trusts and possible ETFs. Japan Exchange Group has also said asset managers are showing interest in crypto-linked products.

Japan’s next steps will depend on how quickly the FSA completes its investment-trust rules and how exchanges set listing requirements. For now, the regulatory changes, asset-manager preparations and growing investor interest have moved the country closer to a domestic Bitcoin ETF market. The latest reported timeline places the first launch as early as 2028, with retail investors potentially providing a large share of demand.
