Investing in Japan without reading Japanese?

Hundreds of disclosures hit EDINET every day — almost all in Japanese. Foreign investors face a real information gap versus domestic players. JSIGNAL closes it: AI reads every filing, summarizes it in English, classifies sentiment, and extracts risk factors — then alerts you on the stocks you watch.

English AI Summaries

Every EDINET filing summarized in clear English by Claude AI — key points, YoY changes, and guidance.

Sentiment & Risk

Each disclosure is classified positive / negative and scanned for emerging risk factors, so you see what matters at a glance.

Watchlist Alerts

Instant email alerts the moment a company you follow files — never miss a market-moving disclosure.

Source data: official EDINET filings.

Coverage note: AI summaries, sentiment / risk classification and English translation primarily cover major EDINET filings — annual securities reports, quarterly / semi-annual reports, large shareholding reports, and share buyback reports — filed on or after the coverage start date. Not all disclosures are covered. Out-of-scope filings may remain in the original Japanese only (you can translate them with your browser).
