Japan vs Korea Stock Market Reform: Why Korea Is 3 Years Behind Japan's Rally

Japan's corporate governance reform doubled the Nikkei. Korea's Value-Up follows the same playbook.

Japan's corporate governance revolution offers a roadmap for Korea's stock market. Between 2014 and 2025, Japan's aggressive push for better shareholder returns, unwinding of cross-shareholdings, and improved governance standards led to the Nikkei 225 more than doubling from 16,000 to 40,000+.

Korea's Value-Up Program, launched in 2024, follows remarkably similar principles. The 'Korea Discount' - where Korean stocks trade at 40-50% lower valuations than global peers - mirrors the 'Japan Discount' that existed before reforms.

Key parallels: Both markets had low P/B ratios (below 1.0x), excessive cross-shareholdings, poor dividend payout ratios, and minimal share buybacks. Japan's reforms proved these structural changes can unlock massive value.

The opportunity for Korea is significant. If Korean financial stocks re-rate from 0.4x P/B to Japan's current 1.0x P/B, that alone represents 150% upside.
