Tokyo Stock Exchange governance reform has moved from campaign to habit — record buybacks, an accelerating cross-shareholding unwind and a Bank of Japan finally normalizing rates are the clearest evidence yet that corporate Japan's capital-discipline drought is ending, though real wage growth (the true test of reflation) is still the weakest link.

| Indicator | Score | Reading |

| Crowding Risk lower is better · high confidence | 73/100 | Foreign flows and the Nikkei's record run show real re-rating momentum, though Japan is re-rating from a historically underowned, cheap base rather than a saturated one. |
| Reflexivity Risk lower is better · high confidence | 33/100 | BOJ policy and yen moves can whipsaw the market sharply, but the core earnings/buyback story remains grounded in real cash flow. |
