Central-government award results published on Japan's Procurement Portal (調達ポータル) 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 (the winning bid) in yen and are never combined with the US federal figures elsewhere on this site. Company and procurement names are shown as published, in Japanese, and are not translated.
