Tohsan Co.ltd

Tohsan Co.ltd, a Japan-based foreign-owned industrial gas supplier, supplies aviator's breathing oxygen, liquid nitrogen, and technical-grade nitrogen to the Department of Defense as a prime contractor across multiple single-award indefinite delivery vehicles, competing full-and-open with no set-aside involvement. The company operates from its facility in Hachinohe, Aomori Prefecture, performing all work directly without subcontractors and has maintained a continuous federal contracting relationship since 2004.

Tohsan's customer footprint is heavily concentrated in Department of Defense logistics and Pacific theater operations. The Defense Logistics Agency Energy accounts for 107 awards and $4.4 million in combined potential value (96% of awards by count, 100% of potential value by dollars), with the Department of the Air Force Pacific Air Forces placing 34 awards valued at $162 thousand and the Department of the Air Force Defense Finance and Accounting Service placing 13 awards valued at $116 thousand. The two rankings align; DLA Energy dominates both volume and dollar metrics. Recent representative delivery orders include a $6,469.50 firm fixed-price delivery order from DLA Energy on December 17, 2024, for aviator's breathing oxygen supporting Pacific theater operations, a $4,790.18 delivery order on March 9, 2026, for nitrogen supply supporting military operations in Japan, and a $52,596.44 BPA call from Pacific Air Forces (October 1, 2024–September 30, 2025) for nitrogen delivery to Misawa Air Base.

Tohsan holds five active parent vehicle contracts, all single-award indefinite delivery instruments issued by DLA Energy and Air Force commands. The primary vehicle, Indefinite Delivery Contract SPE60121D1517, has generated 36 task orders valued at $182 thousand combined potential. A newer single-award Indefinite Delivery Contract (SPE60125R03XX) was awarded April 1, 2026, with a ceiling of $319,345.47 and performance through March 31, 2031, succeeding an earlier $376,043.29 IDIQ contract that expired March 31, 2026. A second vehicle, Blanket Purchase Agreement with Pacific Air Forces (established February 1, 2024, ceiling $93,415.30 through January 31, 2027), authorizes nitrogen chemical delivery and placement at Misawa Air Base on quarterly schedules. Task orders under these vehicles are firm fixed-price, typically ranging from approximately $2,900 to $8,400 per delivery order.

Activity shows steady engagement with the federal customer base: 1 award in 2022, 7 in 2023, 15 in 2024, 10 in 2025, and 4 through April 2026. Combined potential value across all 162 prime awards is $4.7 million, with $3.6 million obligated (77% of potential). The category concentration is narrow: 144 of 162 awards fall under Industrial Gas Manufacturing (NAICS), with 135 awards tagged to the Gases: Compressed and Liquefied PSC code. Tohsan competes exclusively in full-and-open procurement with no set-aside eligibility, reflecting its foreign ownership status. The company produces no subcontracted work and operates entirely as a prime supplier, with all performance occurring at its Japan-based facility supporting U.S. military installations throughout the Pacific region, particularly Misawa Air Base.
