MobilizingThe CRYPTREC Ciphers List (CRYPTREC LS-0001-2022R2) added ML-KEM to the e-Government Recommended Ciphers List for key exchange during FY2025 (year ending March 2025) — the list's own header cites 30 March 2023 as the original issue date and 30 March 2026 as the latest revision date, so the exact day ML-KEM was added should be confirmed against the dated list text rather than assumed. ML-DSA and SLH-DSA (post-quantum signatures) are not yet on the Recommended list; CRYPTREC's MT-1501-2026 working paper records the outstanding questions on adding remaining PQC categories.
Procurement-baseline adoption rather than a dated national migration mandate. Correction: ML-KEM is already listed, not merely 'under evaluation' as previously stated here — only the PQC signature schemes remain pending. Japan is deliberately incremental: algorithms enter the list as evaluation completes, and no deprecation calendar for RSA or ECC has been published.

Procurement lists change what vendors ship into a market long before deadlines appear — but the absence of a deprecation date is itself a finding.
