The tax reform everyone is watching

Current (miscellaneous income)
55%
Maximum progressive rate
→
Proposed (target: January 2028)
20%
Flat rate — if enacted
One caveat: Experts at the BCCC forum noted the 20% rate may initially apply only to assets on JVCEA-certified domestic exchanges — the scope may be narrower than the headline suggests. Long-term holders should also note that a “deemed sale” event may be triggered when moving assets into new specialized accounts at implementation.
Stage 1
2027
FIEA enforcement (if bill passes)
Stage 2
2027–28
Industry preparation
Stage 3
Jan 2028
20% flat tax (if enacted) + ETFs

Government’s stated roadmap. All dates contingent on legislative passage.

Three live FSA payment innovation projects

  • 1 Cross-border yen stablecoin settlements — Pilot with major banks and trading houses testing yen-denominated stablecoins for international trade settlement.
  • 2 On-chain securities settlement — Smart contract-based simultaneous settlement of bonds and stocks, targeting 24/7 operation. The Mizuho/Nomura JGB pilot is part of this track.
  • 3 Interbank tokenized deposits — Enabling cross-bank tokenized deposit transfers, coordinated with the Bank of Japan’s CBDC sandbox.

“Think of Bitcoin and stablecoins as two sides of a coin. Bitcoin is the store of value; stablecoins are the transaction layer. Users can borrow JPYC against their BTC to cover daily expenses — without selling, without triggering a taxable event under current Japanese law.”

— Simon Gerovich, CEO, Metaplanet · CoinPost exclusive interview
