JPX Market Innovation & Research, the research subsidiary of the Japan Exchange Group (JPX), will begin real-time calculation and publication of the JPX Startup Acceleration 100 Index on March 9, 2026. The new benchmark highlights 100 of Japan’s leading high-growth startups and aims to strengthen the visibility of emerging growth companies in the public market.

The index primarily targets companies that have transitioned from the Growth Market within the past five years. However, firms exceeding that timeframe may remain eligible if they continue to demonstrate sustained growth. A buffer rule has been introduced for existing constituents to help ensure stability in index composition.
