House of Representatives A1
House of Representatives: award results compiled from the open award-results data published on Japan's Procurement Portal (調達ポータル).
Central-government awards published on the Procurement Portal only. Prefectural and municipal contracts are not included, and neither is the Ministry of Defense's central equipment procurement, which ATLA (Acquisition, Technology and Logistics Agency) publishes separately. Amounts are award prices in yen, not converted to dollars. The window is a rolling 60 months by award date, not a fiscal year. Counts are counts of award-result rows (one per winner when a procurement has several), not counts of procurements.
