Japanese Equities Hit New All-Time High As Corporate Reform Cycle Matures

Japanese equities reached a new all-time high this week, with the TOPIX index breaking through 3,200 for the first time and the Nikkei 225 closing within a small distance of its own record, in a move that vindicates the corporate-reform thesis that has drawn foreign capital into the market since the start of the cycle.

The driver remains structural rather than cyclical. The Tokyo Stock Exchange's reform programme — and the public pressure on companies trading below book value — has now produced two consecutive years of accelerated buyback announcements, dividend uplifts, and cross-shareholding unwinds. Aggregate Japanese corporate cash returned to shareholders in the year to March hit ¥27.4 trillion, an all-time high and roughly 22% ahead of the previous record.

Foreign investor flows have responded. Net buying by overseas accounts in the year-to-date is the strongest since 2013, the year of the original Abenomics rally. Importantly, the composition of buyers is different this time: the flow is more sticky long-only rather than the macro hedge-fund money that dominated the earlier cycle, suggesting a more durable allocation shift.

The yen has been a complicating factor. Currency depreciation through 2024 supercharged the local-currency returns for foreign investors only modestly because the underlying earnings translation worked the other way. With the yen now stable and likely to strengthen modestly through the rest of the year, some of that translation tailwind is in reverse — but underlying corporate fundamentals are strong enough that analyst consensus still expects double-digit profit growth at the index level.

Risks have not disappeared. Bank of Japan policy normalisation continues to introduce volatility into the bond market, and the demographic and productivity headwinds that defined the previous decade have not gone away. But the combination of corporate self-help, foreign flows, and a more disciplined macro framework has produced a market that finally rewards the patience long-term Japan watchers have spent two decades cultivating.
