Seikitokyu Kogyo Co., LTD.

Seikitokyu Kogyo Co., LTD. Iwakumi Branch, a foreign-owned Japanese construction and infrastructure services company, operates as a prime contractor (100% of recent awards) providing airfield pavement maintenance, facility repair, and design-bid-build construction services to the U.S. Marine Corps at Marine Corps Air Station Iwakumi and other Pacific installations. The company is headquartered in Iwakumi, Yamaguchi, Japan, and holds active registration in the System for Award Management; all federal awards are issued without set-aside designations and reflect full-and-open competition. The vendor operates exclusively in Japan and competes on capability and performance history rather than socioeconomic status.

Seikitokyu Kogyo's federal footprint is heavily concentrated in Marine Corps airfield and facility infrastructure. The Marine Corps accounts for 13 of 14 awards (100% of combined potential value $270.5 million), with a single $167 thousand purchase order from the Department of the Army Installation Management Command Pacific Region for DEMIL wastewater treatment plant repair at Kawakami Ammunition Depot in Hiroshima. The vendor's work centers on airfield pavement repair, joint sealant replacement, taxiway and runway maintenance, and associated facility work under primary NAICS codes for highway and bridge construction (10 awards) and building construction (3 awards). Representative recent delivery orders include a $1.75 million firm fixed-price order for taxiway asphalt pavement shoulder repair at MCAS Iwakumi (awarded January 30, 2026, completion July 2027), a $748.7 thousand order for underground steam double-pipe replacement at the station (March 2025), and a $593.3 thousand order for airfield partial-depth patching (September 2025).

Seikitokyu Kogyo holds two IDIQ vehicles with the Marine Corps: a $15.3 million single-award Airfield IDIQ (N4008423D5501) running through August 2028, under which nine task orders have been placed ($4.4 million combined potential value), and a $250 million multiple-award Mini MACC Design, Bid, Build Japan contract (N4008424D0083) for small-scale design-bid-build projects across office renovations, building demolition, electrical and mechanical work, and facility maintenance through August 2029. Task orders under these vehicles range from minimum-guarantee awards under $10 thousand to project-specific work in the seven-hundred-thousand-dollar range. Award volume has grown from three awards in 2023 and 2024 each to seven in 2025, with one award to date in 2026. Only three awards (combined potential value $2.7 million) reach ultimate completion within the next twenty-four months, limiting near-term recompete exposure. The vendor maintains all work performance at MCAS Iwakumi and other U.S. military installations in Japan and holds valid Japanese government construction licensure required under its contract vehicles.
