Figures below come from this company's annual securities report (有価証券報告書) filed with Japan's Financial Services Agency. Filing a false statement is a criminal offence, which is what makes them worth building on.
Corporate Number 8070001009687 (National Tax Agency)
Japan requires listed companies to disclose these three ratios. They are useful but easy to misread — the notes matter.
| Item | Value | What it does not tell you |
|---|---|---|
| Female managers | 25.0% | definition of 'manager' varies by company |
| Male parental leave | — | can exceed 100%; says nothing about duration |
| Gender pay gap (all workers) | 67.2% | women's pay as % of men's; not equal-work comparison |
| Workplace score (beta) | 48.4 | deviation vs all listed, 50 = median |
| Investment score (beta) | 48.6 | deviation vs all listed, 50 = median |
From past annual securities reports. Reorganisations move this figure even when pay itself does not — the average covers the filing entity only.
| Fiscal year end | Average annual pay |
|---|---|
| 2024-03-31 | ¥4.6m |
| 2025-03-31 | ¥4.8m |
| 2026-03-31 | ¥4.9m |
Same sector, closest by average pay. A starting point for comparison — not a ranking. Pay differences here are driven as much by average age and by how much of the group sits inside the filing entity as by how well a company pays.

| Daito Pharmaceutical Co., Ltd. | ¥4.9m | 39.0 | 4577 |
