About the company
Alpha Rinks Co., LTD., a Tokyo-based for-profit facility maintenance and construction contractor, executes purchase-order work for the U.S. Department of State as a prime contractor in the full-and-open market, with no set-aside participation. The vendor operates exclusively in Japan, delivering specialized facility renovation, remediation, and installation services to support U.S. diplomatic and consular missions.
Alpha Rinks Co., LTD. serves a single customer agency across all eight prime awards: the Department of State, fragmented across three bureaus. The Bureau of Overseas Building Operations accounts for 5 awards totaling $167 thousand; the Bureau of East Asian and Pacific Affairs holds 2 awards worth $50 thousand; and the Bureau of Consular Affairs holds 1 award at $30 thousand. Combined potential value across all awards stands at $247 thousand, with 100% of that value obligated. Work is characterized by facility construction and renovation projects classified under Other Building Finishing Contractors (5 awards) and Residential Remodelers (3 awards), with PSC coding concentrated on family housing repair or alteration and maintenance. Representative contracts include a $91.7 thousand bathroom restoration at a consular office (September 2024, Bureau of Overseas Building Operations), a $35.3 thousand ceiling reinforcement service (August 2025, Bureau of East Asian and Pacific Affairs), and a $31.5 thousand mold remediation and restoration contract (August 2025, Bureau of Overseas Building Operations). The vendor's most recent award, a $11.8 thousand mold remediation purchase order from the Bureau of Overseas Building Operations, was awarded on February 6, 2026, with completion targeted for April 30, 2026.
Activity has grown modestly over the source window: three awards in 2024, four in 2025, and one in the first five months of 2026. The vendor carries no subcontract relationships and does not appear on government-wide acquisition contracts, BPAs, or agency-wide IDIQs. All eight awards are individual purchase orders. Given the narrow geographic and customer focus, Alpha Rinks Co., LTD. operates as a localized facility-services provider for U.S. government properties in Japan rather than a federal contractor competing for work outside that market.
