Kyunan Co., LTD.

Kyunan Co., LTD., a Japanese construction firm headquartered in Miyakonojo, Miyazaki, holds three major indefinite-delivery/indefinite-quantity (IDIQ) contracts with the U.S. Department of Defense and executes design-build and design-bid-build construction services as a prime contractor exclusively at U.S. military installations in Okinawa, Japan. The vendor does not subcontract and competes without set-aside designation in full and open procurement.

Kyunan's capability portfolio centers on facility maintenance, repair, renovation, and new construction across military real estate, with a track record spanning HVAC system replacements and air conditioning upgrades (ranging from $183 thousand to $3.9 million), roofing repairs and hazardous material abatement, electrical system upgrades, water and sewer line installation and repair, structural concrete repairs, building demolition, interior and exterior refurbishment, and specialty systems work such as fire alarm antenna installation and aqueous film-forming foam fire suppression system repair. Recent representative awards include a $21.2 million definitive contract with Pacific Air Forces for Phase II water line repair around Kadena Air Base (awarded September 2025), a $5.6 million design-build delivery order with the Marine Corps for AFFF fire suppression system repair at Building 618, Camp Kinser (awarded June 2022), and a $3.9 million design-build task order with Pacific Air Forces for water pipe replacement at Naha Port (awarded June 2022).

Customer concentration is extreme and single-agency dominant. Pacific Air Forces accounts for 71 awards and $5.13 billion in combined potential value (83% of total dollars), while the Marine Corps holds 49 awards and $933.9 million. These two customers represent 94% of all awards by count and 99% of potential value. The top five customers (including Navy Installations Command, Defense Finance and Accounting Service, and Army Installation Management Command Pacific Region) account for 144 of 154 awards. The dollar concentration is far steeper than the volume concentration — Pacific Air Forces' $5.13 billion ceiling represents 83% of the vendor's total $6.19 billion portfolio, while its 71 awards are only 46% of the 154-award total.

Kyunan's vehicle position reflects its entrenched role at Okinawa military installations. The vendor holds seats on the Kadena Multiple Award Construction Contract (49 task orders, $213.2 million combined potential value, awarded by Pacific Air Forces), the Indefinite Delivery Contract FA527013D0003 (38 task orders, $2 million, also Pacific Air Forces), the NAVFAC Okinawa Construction 2016-2021 contract (19 task orders, $11.6 million, Naval Facilities Engineering Command), the Design Build MACC for Various U.S. Government Installations at Okinawa Prefecture Japan ($625 million ceiling, 13 task orders, $29.8 million), and the Camp Butler and Commander Fleet Activities Okinawa Design-Bid-Build MACC ($250 million ceiling, 11 task orders, $5.9 million, Marine Corps). The vendor also recently received award of a new $995 million Okinawa Multiple Award Construction Contract from Pacific Air Forces on September 3, 2025, extending through September 2, 2028, establishing Kyunan's largest single vehicle to date.

Activity has been steady with modest growth. Awards per year ran 11 (2022), 11 (2023), 14 (2024), and 17 (2025), with only one award recorded in 2026 to date. The recompete cliff in the next twenty-four months is modest: ten awards with combined potential value of $15.8 million reach ultimate completion by mid-2028, creating limited near-term competitive vulnerability. However, the vendor's obligation rate is extremely low — only $162 million in combined dollars obligated against $6.19 billion in potential value (3%) — indicating that most of the portfolio ceiling represents pipeline capacity rather than contracted work.

Kyunan has been registered in the System for Award Management since June 2008 and has maintained continuous federal contracting relationships with the Marine Corps, Pacific Air Forces, Naval Facilities Engineering Command, and Navy Installations Command throughout the source period. The vendor is foreign-owned (Japanese corporate entity, tax exempt structure per SAM registration), operates exclusively in Japan, and maintains no known subcontracting relationships within the federal footprint captured in the source. Work is performed entirely at or in support of U.S. military facilities throughout Okinawa Prefecture, with no CONUS or third-country exposure.
