Japanese Bitcoin ETF Could Hit $18.4 Billion: Here’s Why Analysts Think So

Japan could become the next major market for spot Bitcoin ETFs if regulators eventually approve the products, according to a new estimate featured by Nikkei. Citing CryptoQuant analyst Jai Hamid, the report outlines a bullish scenario in which Japanese spot Bitcoin ETFs could accumulate up to $18.4 billion in assets by fiscal 2028.

The estimate is not presented as a prediction or guaranteed outcome.

Instead, it represents what Hamid describes as an “achievable upper-end market scenario” based on Japan’s financial landscape, the country’s investment habits, and the adoption trajectory seen in the United States since spot Bitcoin ETFs launched in January 2024.

Moreover, the report comes at a time when traditional financial institutions are increasingly adopting the crypto ethos in their own operations.

The U.S. Bitcoin ETF Boom Offers a Blueprint

The analysis starts with the sheer size of Japan’s financial market. According to the report, Japanese households collectively hold roughly $14.6 trillion in financial assets, meaning an $18.4 billion Bitcoin ETF market would account for only 0.13% of household wealth.

Another comparison underscores how modest the estimate actually is. The projected ETF market would equal around 1% of Japan’s public equity investment fund market, which exceeds $1.8 trillion.

Hamid argues that demand could come from three distinct groups: existing crypto investors seeking a regulated investment vehicle, traditional retail investors using brokerage accounts and Japan’s tax-advantaged NISA investment program, and larger allocations from wealthy individuals, corporations, and financial institutions.

The experience in the United States provides the strongest supporting evidence. As Hamid noted, “excluding GBTC, spot Bitcoin ETFs expanded their holdings to around one million BTC,” demonstrating how exchange-traded funds can bridge traditional finance and digital assets.

Access Could Be the Biggest Catalyst

According to the report, the biggest advantage of a Japanese spot Bitcoin ETF would not necessarily be lower costs or higher returns, but accessibility.

Rather than opening accounts on crypto exchanges or managing private wallets, investors could gain Bitcoin exposure through familiar brokerage platforms, regulated custodians, and existing securities infrastructure. That mirrors one of the key drivers behind the success of U.S. spot Bitcoin ETFs, which collectively attracted tens of billions of dollars after launch.

The chart above also illustrates how Bitcoin ETF holdings in the U.S. expanded rapidly after approval, excluding Grayscale’s GBTC, before stabilizing around the one million BTC mark. That growth serves as the primary benchmark behind the Japanese projection.
