02 / What it does

Screen every listed company, from a conversation.

Metric catalog

Katana's metrics (Japanese/English names, units, missing counts) and the syntax for period aggregates and custom formulas.

Preset screens

The 12 preset screens published on the website.

Screening

Filter every listed company in Japan by financial conditions, period aggregates, custom formulas, and words in annual reports.

Company history

Latest metrics and up to 10 fiscal years of financials for one company.

Word conditions check whether a term appears in seven main sections of the latest annual securities report (business description, business environment, business risks, results, R&D, material contracts, affiliated entities). Dividend policy and capital expenditures are searched only when chosen. Results show which sections matched; report text is not returned.

03 / Example requests

Ask in words. The AI builds the conditions.

“Using Katana, find companies whose profit would rise most from higher interest income as rates go up”
“Katana: 5-year revenue CAGR of 10% or more, and 'データセンター' in the business description”
“Show Katana's preset screens and run the Graham one”
“Toyota (7203): 10 years of operating income and cash flow from Katana”

04 / About the data

The same data as the website.

Source: annual securities reports on EDINET (Financial Services Agency of Japan), processed by Katana. Same data as the website, updated every morning.
Amounts in JPY; ratios as decimals (0.5 = 50%). Price-based metrics are as of each fiscal year end, not current prices.
