Financial statements (P/L, B/S, C/F) of 3,634 Japanese listed companies from official EDINET filings, normalized across J-GAAP, IFRS, and US GAAP with English keys. One 4-digit company code returns income statement, balance sheet and cash-flow items in absolute JPY, with the accounting standard auto-detected (IFRS / Japanese GAAP / US GAAP). Items that don't exist under a company's standard are returned as null with a reason — never approximated. Every response carries the source document ID and submission date, traceable to the original EDINET filing. Public disclosure data only — not investment advice.
