About IPO Rader Japan

IPO Rader Japan is the first English-language analytics dashboard purpose-built for the Japanese IPO market. We translate, structure, and visualize data from Japanese filings so global investors can discover opportunities without reading Japanese.

The Problem

Japan’s IPO market is one of the largest in the world — over 80 companies list on the Tokyo Stock Exchange each year, with a combined market value exceeding $8 billion. Yet virtually all IPO information is published exclusively in Japanese, creating a significant barrier for international investors.

First-day returns on Japanese IPOs frequently exceed 100%, and post-IPO secondary opportunities emerge as lock-up periods expire. Despite this, no dedicated English-language tool existed to track these events — until now.

What We Do

• Track — Monitor upcoming, active, and recent IPOs on TSE Prime, Standard, Growth, and Tokyo Pro markets.
• Translate — Extract and translate company profiles, financials, risk factors, and use of proceeds from Japanese securities filings.
• Analyze — Screen IPOs by segment, sector, growth rate, offer size, and VC overhang risk. Visualize post-IPO performance with cohort heatmaps and scatter plots.
• Alert — Get notified about new listings, book-building opens, offer price announcements, and lock-up expirations.
