Corpus compiles information on Japanese listed companies using only documents they are legally required to file. The core source is the annual securities report (有価証券報告書), filed with the Financial Services Agency and published through EDINET. Filing a false statement is a criminal offence, which is what makes these figures worth building on.

Sources

• EDINET (Financial Services Agency) — annual securities reports, extraordinary reports, large shareholding reports, tender offer reports. Retrieved through the official API.
• e-Stat (Statistics Bureau) — Basic Survey on Wage Structure, used as the peer benchmark for the salary-vs-benchmark figure.
• gBizINFO (METI) — corporate identifiers and official websites. Processed by this site.
• J-Quants (JPX Market Innovation & Research) — market capitalisation and financial summaries, on a roughly 12-week delay (free tier).

Limitations you should know

• Average annual salary is the filing entity's figure, usually the parent company on a non-consolidated basis. Subsidiary employees are not included. Holding companies can look misleadingly high.
• Individual director pay is only disclosed above ¥100m (consolidated). Statistics on executive pay therefore cover a minority of companies and skew high.
• Scores are our own constructs, expressed as deviation values against all listed companies. They are a statistical position, not a verdict on a company.
• This is not investment advice. We present public disclosure; decisions are yours.

Figures are compiled independently and are not provided or endorsed by any government agency. Full disclosure of method, disclaimers and privacy policy is in the Japanese edition: このサイトについて ・ プライバシーポリシー. Corrections and takedown requests: contact form (Japanese).
