Bank of Japan's blockchain settlement sandbox and the digital-yen decision

Bottom line: testing central-bank money on a blockchain
On 2026-03-03 the Bank of Japan announced a sandbox testing settlement using central-bank money (current-account deposits) on a blockchain. The BOJ is expected to decide this year whether to issue a retail digital yen (CBDC) — but no decision has been made.
Key points
- BOJ is testing blockchain settlement of central-bank money (sandbox).
- A decision on a retail digital yen is expected this year.
- Experiments have run since 2021; Japan also joins cross-border Project Agorá.

CBDC vs crypto
A CBDC is central-bank money in digital form — issued and managed by the central bank, pegged to the yen — unlike decentralized crypto whose price floats on the market.
Research stage
A retail digital yen is not decided. Outcomes depend on the experiments and public consensus. Check the Bank of Japan for the latest.
