Edition 2026-10 of the Japan Web Infrastructure Posture radar measured 5,792 sites in 7 sectors (passive measurement of public data, as of 26 Oct 2026). 96 % of finance sites and 100 % of central-government sites have RPKI-valid routes; post-quantum TLS key exchange is offered by 74 % of finance and 90 % of central-government sites. This is the first edition in the archive, so no comparison is given.
