Japan is preparing one of its biggest crypto reforms to date as regulators move to classify digital assets as financial products, introduce insider trading rules and cut the tax rate on crypto trading.

Insider rules and a lower tax rate

Under a draft framework reported by Asahi Shimbun, Bitcoin, Ethereum and more than one hundred other tokens listed domestically would be treated like securities.

Exchanges would need to publish detailed information for each asset, including whether an identifiable issuer exists, how the technology works and the scale of price risk. Anyone with non-public information about issuers or trading venues would be barred from trading ahead of major events such as listings, delistings or bankruptcies. The shift would pull crypto into the same market conduct regime that governs equities.

Tax treatment would also change. Trading profits would fall under a flat 20% rate, in line with stock investments, instead of being taxed as miscellaneous income with a top rate around 55%. A simpler regime could draw activity back onshore, discourage the use of offshore platforms and make reporting easier for domestic investors.

The plan would widen distribution, too. Banks and insurers could sell approved cryptocurrencies through their securities arms, placing digital assets on mainstream investment platforms rather than limiting access to specialist exchanges. The FSA aims to submit legislation during next year’s ordinary parliamentary session.

Mixed signals for market growth

The reform push comes as other authorities take a more cautious stance on crypto exposure among listed companies. Japan Exchange Group, which operates the Tokyo Stock Exchange, is considering stricter backdoor listing tests and fresh audits for firms shifting into large digital asset positions.

Since September, three listed firms have paused plans to buy crypto after being warned that aggressive token accumulation could limit their ability to raise capital.

The result is a split message from Tokyo. The FSA is moving to normalise crypto by aligning disclosures, conduct rules and tax treatment with traditional finance. The exchange operator is tightening scrutiny of corporate balance sheets that lean heavily on Bitcoin or other tokens.

For global firms and investors, Japan looks more open to regulated crypto trading, but less tolerant of equity stories built on large-scale token holdings.
