Japan Tightens Crypto Security with New Custody Registration Rule for 2026

The post Japan Tightens Crypto Security with New Custody Registration Rule for 2026 appeared first on Coinpedia Fintech News

Japan is preparing a new rule that could significantly change how crypto assets are stored and handled in the country. The Financial Services Agency (FSA) wants any company holding or managing crypto for exchanges to be officially registered with the government. This means every custody or trading-management provider must prove it is secure and compliant before touching user assets.

Why Japan Is Doing This

Crypto exchanges in Japan already have strict rules. They must protect user funds, store most assets in cold wallets, and maintain clear internal controls. But there is a loophole: these rules don’t apply to outside companies that exchanges hire for custody or trading support.

That gap turned into a real problem in 2024. DMM Bitcoin, one of Japan’s major exchanges, was hacked, losing ¥48.2 billion (about $312 million) worth of bitcoin. The hack didn’t happen inside the exchange itself. It originated through a third-party software firm, Ginco, which handled part of the exchange’s trading operations. The incident exposed a major weakness: even if exchanges are secure, an unregulated outside partner can put user funds at risk.

What the New Rule Would Do

Under the plan, companies providing crypto custody or trading services must register with authorities before operating. Exchanges will only be allowed to use custodians that appear on the government’s approved list. In short, if a provider is touching user assets in any way, it must meet the same security standards as the exchange itself.

Members of Japan’s Financial System Council, which advises the Prime Minister, discussed the proposal on November 7. According to reports from Nikkei, most members supported the change. The FSA plans to turn these discussions into a formal proposal and aims to submit amendments to existing financial laws during the 2026 parliamentary session.

What It Means for Crypto Users

The rule comes at the same time Japan is actively pushing forward new crypto and blockchain initiatives. The FSA recently approved Japan’s first yen-backed stablecoin, JPYC, and is supporting a stablecoin pilot involving Japan’s three major banks, Mizuho, MUFG, and SMBC. These projects show that Japan wants to lead in digital finance, but without compromising safety. For everyday crypto holders, this move means more protection. Exchanges won’t be able to outsource critical operations to unknown or poorly secured companies. Everything touching user assets would require government oversight and registration.
