Prime Minister Sanae Takaichi — Japan’s 105th PM — delivered a video address at WebX 2026, the Bitcoin and digital-assets conference in Tokyo. Not a hedge fund panel. Not a supporter tweet. The nation’s top political office publicly aligning with “technologies that will shape the finance of the next era.” The Fundamentalist read is direct: when the political class of a major sovereign that runs the world’s third-largest bond market publicly endorses Bitcoin-native financial rails, the ruler-shrinks / cap-stays-fixed argument stops being an editorial thesis and becomes a policy premise. Warren wants a Senate hearing on Bitcoin. Takaichi already gave the keynote.
