Japan is gearing up to launch its first Bitcoin ETFs, which analysts predict could manage assets totaling $18.4 billion, or roughly 3 trillion yen, by the fiscal year 2028. This forecast stems from an extensive pool of household savings that currently sits idle in bank accounts, amounting to $14.6 trillion. Viewed in this context, the anticipated Bitcoin ETF market size represents a small slice, about 0.13%, of that vast sum.
Where the Investment Will Come From
Three main sources are expected to drive inflows into Bitcoin ETFs:
- Retail investors, who will gain access to Bitcoin through familiar investment platforms and tax-favored NISA accounts. A tax reform proposal aims to reduce the crypto income tax rate from 55% to 20%, potentially increasing investor interest.
- Institutional investors, including pension funds, attracted by Bitcoin’s low correlation to the US dollar and its potential as an inflation hedge. The National Business Pension Fund in Okayama has already allocated 1% of its assets to cryptocurrencies.
- Major domestic financial corporations like SBI Holdings, which plans to launch several ETFs, including one combining Bitcoin and XRP. SBI aims to reach 5 trillion yen in assets under management within three years, a pace that could push the market beyond the $18.4 billion estimate before 2028.
This emerging market compares modestly to Japan’s equity investment fund sector, where Bitcoin ETF inflows would represent about 1% of the total fund size. The gradual entry of conservative institutional capital and the appeal to retail investors through simplified and tax-advantaged products could reshape the country’s crypto landscape.
