Resolve a company name, EDINET code, or securities code to a company record. Use this first when you know WHO you are looking for and need its EDINET code for the other tools. For finding companies by numeric criteria you do not yet have a name for, use screen_companies instead.

Get the full profile of one company: identifiers, industry, market segment, headcount and the most recent reported financial summary. This is the general 'tell me about this company' tool; for a multi-year numeric series use get_financials.

Get the multi-year financial statement time series for one company — revenue, operating income, net income, assets, equity and cash flow per period. Figures come from XBRL in the company's own regulatory filings; no language model is involved in producing them.

Get the reported business-segment breakdown for one company: revenue, operating income, assets, depreciation and capital expenditure per segment. Use this to see which part of a business actually earns money, which consolidated totals in get_financials cannot show.

Get a company's quarterly earnings releases (決算短信) newest first, including reported results and management's own forecast for the year. These arrive weeks before the annual report, so use this for the latest numbers and get_financials for the audited long-run series.

List the regulatory documents one company filed in a given period, with filing dates and document types. Use this to answer 'what did they file and when'; use get_text_blocks to read the narrative content of a filing.

Read the narrative sections of a company's annual securities report — business overview, risk factors, and management's discussion and analysis — as the original filed Japanese text. Returns a 2,000-character excerpt per section unless full is set.

Get the board roster disclosed by one company: each director and corporate auditor with their title, responsibilities, tenure and shareholding. Answers governance and board-composition questions.

Get the large-shareholding reports filed against one company — who has declared a stake of 5% or more, at what ratio, and as of when. This is the issuer-side view; to go the other way and see everything one investor holds, use search_shareholders.

Look up an investor by name and get every listed company where it has filed a large-shareholding report. This is the reverse of get_shareholders: start from the holder, not the issuer.

Filter the whole universe of Japanese listed companies by numeric and categorical criteria combined with AND, and sort the survivors. Use this when you are looking for companies that match a profile; use search_companies when you already know which company you mean.

Get the market-wide league table for one metric — the top companies by return on equity, market capitalisation, dividend yield, female director ratio and 45 others. Use this for 'who is highest on X'; use screen_companies when you need several conditions at once.

Benchmark one company against its industry peers on a single metric over several years, returning the company's own series, each peer's series and the industry distribution. Answers 'is this good?', which a single company's numbers alone cannot.
