Buyo Gas Co.,Ltd.

Buyo Gas Co.,Ltd., a Japanese corporate entity, serves as the sole prime contractor for natural gas and propane utility services to U.S. Air Force installations in Japan, holding a $94.8 million single-award Indefinite Delivery Contract with Pacific Air Forces that runs through March 31, 2030. The vendor operates exclusively under full-and-open federal procurement—no set-aside designations across the entire portfolio—and has maintained an unbroken federal contracting relationship with PACAF dating to at least 2003.

Buyo Gas's customer footprint is entirely concentrated with a single federal agency. The Department of the Air Force Pacific Air Forces accounts for all 21 awards in the source data, representing $392 million in combined potential value. This extreme concentration reflects the vendor's role as the designated utility provider for Yokota Air Base, a critical Pacific installation requiring 24/7 natural gas service delivery across five supply points, including residential connections and base operations. The vendor's work is classified under NAICS 424520 (Natural Gas Distribution) for 15 of 21 awards, with the remainder split across petroleum products merchant wholesaling and equipment maintenance, and under PSC categories Utilities—Gas (10 awards) and Liquid Propellants and Fuels, Petroleum Base (5 awards).

The vendor holds three active parent IDCs with PACAF. The oldest and largest, Indefinite Delivery Contract FA520920D8001, carries a $59.6 million combined potential value across nine task orders. IDC FA520914D0002 spans four task orders worth $36.5 million, and the recently awarded IDC FA520925D8000 covers three task orders at $15.9 million. Recent delivery orders include an $8.9 million contract awarded October 1, 2025, a $7.0 million delivery order from April 1, 2025, and a $9.15 million order from October 2024, all firm fixed-price arrangements running through March 31, 2025 or 2030 depending on the vehicle. The vendor also holds a separate subsidiary arrangement through Buyo Ekika Gas Co., Ltd., valued at $194,855.84, for propane supply to Yokota Air Base and Tama Service Annex.

Activity has remained flat at two awards per year through 2024, with uptick to four awards in 2025. The vendor has obligated $112 million (29% of combined potential value) to date, indicating substantial future performance under existing IDC authority. With a long-standing federal contracting history and monopoly position on natural gas supply to a strategic Pacific installation, Buyo Gas operates with minimal recompete exposure within the next twenty-four months as long as PACAF's utility requirements remain stable.
