Japan plans separate tax treatment for crypto ETFs and derivatives
Japan’s Financial Services Agency (FSA) is advancing proposals to authorize exchange-traded funds (ETFs) backed by specific cryptocurrencies, a move that fleshes out previously reported plans to apply a flat 20% separate tax to crypto gains. According to agency materials released on Dec. 26 and reported by CoinPost, the regulator has now clarified that crypto-linked ETFs and derivatives will be integrated into this new tax framework.

The materials, part of the tax reform framework for the fiscal year 2026, indicate that the regulator intends to align the tax treatment of crypto-linked ETFs with that of stocks and foreign exchange trading.
Under the current system, cryptocurrency gains in Japan are classified as miscellaneous income, subjecting investors to progressive tax rates that can reach approximately 55% when local levies are included. The proposed reforms aim to integrate crypto assets into the Financial Instruments and Exchange Act (FIEA), a legislative package slated for debate during the 2026 Diet session.
Derivatives also subject to separate tax
Beyond ETFs, the regulator plans to adjust the taxation of derivative products based on certain crypto assets. While these derivatives would remain classified as miscellaneous income—similar to conventional futures—the method of taxation would shift from comprehensive taxation to a separate self-assessment model.
Despite the outlined tax reductions, market observers anticipate that full implementation may be delayed until 2028 due to the time required to amend the relevant laws and government ordinances.
FSA restructures to better oversee crypto
In parallel with regulatory updates, the FSA is restructuring its internal operations to better address digital finance. Nikkei reported that the agency has decided to elevate its Crypto-Assets and Blockchain Innovation Office to the status of a division beginning in the administrative fiscal year starting July 2026.
This restructuring follows an August proposal in which the FSA cited the need to bolster its capacity to handle financial services transformed by financial technology, crypto trading, and generative artificial intelligence (AI). The agency noted that it faces accumulating challenges, including fraud prevention and the government's broader goal of positioning Japan as a leading asset management nation.
Additionally, the establishment of a new Asset Management and Insurance Supervision Bureau is expected as part of the reorganization.
The regulatory shifts coincide with broader efforts to integrate blockchain technology into Japan's financial infrastructure. A separate Nikkei report last week stated that policymakers have agreed to prepare for the issuance of local government bonds as blockchain-based security tokens. The government plans to submit the necessary legislation during the next ordinary Diet session, aiming to streamline settlement processes and enable real-time monitoring of investor data.
Corporate crypto strategies persist despite concerns
In the private sector, Tokyo Stock Exchange-listed Metaplanet is proceeding with a corporate strategy focused on Bitcoin accumulation. Dylan LeClair, the company's Director of Bitcoin Strategy, said on X that shareholders at an extraordinary meeting approved proposals to raise capital for additional Bitcoin purchases, including the issuance of Class B preferred shares to overseas institutional investors.
Earlier this year, Metaplanet shareholders authorized a long-term plan to acquire more than 210,000 Bitcoin by 2027, representing roughly 1% of the total supply.
However, analysts warn that corporate models based primarily on asset accumulation face structural risks. According to Cointelegraph, industry figures such as MoreMarkets CEO Altan Tutar and Solv Protocol co-founder Ryan Chow have cautioned that companies relying solely on digital asset holdings may struggle to maintain valuations without developing operational businesses that generate consistent returns.
