Supplier counts are distinct corporate number (法人番号)s, not award counts: a company that wins repeatedly counts once.
How to read this
Value and volume are distributed differently. The top five bodies hold 53.7% of the value, but all 45 bodies have recorded awards, and the median body (Public Prosecutors Office) still recorded 2,889 awards worth ¥31,955,770,479.
This shows how published award results are distributed. It does not measure how open any agency is to new suppliers, and a large figure says nothing about how strong the competition is.

Method
- Hashike ingests the award-result files the Procurement Portal publishes and aggregates them by ministry code into counts, values and distinct corporate numbers. Only records with an award date between 2021-10-16 and 2026-10-16 are included.
- Shares are each body's recorded value over the recorded total. Nothing here is estimated.
What this does not tell you
- Central-government award results only. Local and prefectural procurement, some independent administrative institutions, and anything not published on the Procurement Portal are outside this dataset.
- The window runs 2021-10-16 to 2026-10-16. Awards outside it are not counted.
- All amounts are in yen and are never combined with, or compared against, the US federal dollar figures elsewhere on this site.
- Awards whose corporate number cannot be resolved from the record are missing from the supplier figures. That is a gap in the record, not an absence of activity.
