Depth over speed: the real story is in the statutory filings

The information that moves Japanese stocks — the basis for full-year results and guidance, risk factors, ownership changes (5% reports), takeovers and tender offers — lives in EDINET statutory filings (like annual securities reports), not in earnings flashes. A tanshin is only a summary, and the detail is in Japanese. JSIGNAL turns these dense, decision-grade filings into English AI summaries with risk and growth analysis — so you understand the names you follow with precision, not just speed.

Activist & Ownership Tracker

From 5% large-shareholding reports: who holds what %, the change vs the last filing, and the stated purpose (pure / policy / activist). Spot moves early.

TOBs & Key Filings, in English

Tender offers, annual and extraordinary reports turned into clear English AI summaries — with sentiment, risk and growth.

Watchlist Alerts

Instant email alerts the moment a name you follow files — including 5% ownership and tender-offer moves.

How AI analysis works

From official filings to investor-ready insight — fully automated.

Coverage (EDINET-focused)
JSIGNAL focuses on filings from EDINET (Japan's statutory disclosure system, run by the FSA): annual & quarterly securities reports, extraordinary reports, large-shareholding (5%) reports and tender offers (TOB) — the substantive, hard-to-read statutory filings, summarized in JA/EN by AI. Note: TDNET timely disclosures (e.g., earnings flash / kessan tanshin) are NOT included.
Why statutory filings: Annual securities reports carry the detailed business, risk and capital-policy disclosures that let AI produce precise analysis. Earnings flashes (tanshin) are already summaries — less suited to deep analysis. For investment decisions, precision matters more than real-time speed. JSIGNAL prioritizes depth and accuracy over breaking news.
