Built on EDINET annual filings · no login · English interface
Japan has roughly 3,800 listed companies and a well-earned deep-value reputation, but the tools for finding those companies are almost all Japanese-only or paywalled. Katana exists to close that gap: a screener that runs on official annual-report data, in English, that you can use immediately without an account.
Free, no registration, no email required.
Everything is derived from annual securities reports filed on EDINET, the Japanese government's disclosure system — audited, primary-source documents rather than scraped aggregator data. Figures are recomputed from the filings each morning. If EDINET is new to you, the research guide explains how Japan's disclosure system works and what makes this market unusual.
Price-related values — share price, market capitalisation, and every multiple derived from them — are as of each company's fiscal year-end, back-calculated from the trailing P/E disclosed in the filing. They are not real-time quotes and will differ, sometimes substantially, from today's market. Katana is a tool for building a shortlist from fundamentals, not for timing a trade. Always check the current price before acting.
The target is every TSE-listed company, and names are being added progressively rather than all at once. A company missing from a screen has not necessarily failed it — it may not be loaded yet.
Because the source is the annual report rather than quarterly summaries, a given company's figures refresh once a year, when its new filing lands. Most Japanese companies close their books in March, so the bulk of the dataset turns over in June.
Katana reports what companies disclosed about themselves. It does not rank, recommend, or express a view on any security, and no preset should be read as an endorsement of the methodology it reproduces.
