Tanakagumi Co.,Ltd.

Tanakagumi Co., Ltd., a Japan-based construction and infrastructure services contractor, delivers facilities sustainment, repair, electrical systems upgrade, and general construction services to the U.S. military across Indo-Pacific installations, competing exclusively as a prime contractor without small business set-asides.

Tanakagumi is a for-profit corporate entity headquartered in Oirase, Aomori Prefecture, Japan, registered in the System for Award Management since April 2004. The vendor competes in full-and-open procurements and holds no SBA certifications. Its concrete capability portfolio centers on electrical infrastructure repair and modernization (switching stations, substations, feeder lines, grounding systems), building systems maintenance (HVAC, exhaust ducts, lighting upgrades), structural demolition, mechanical lock conversion, road repair, and general design-build construction services across architectural, structural, civil, mechanical, fire protection, and demolition disciplines. Representative recent awards include a $3.7 million delivery order from Pacific Air Forces in February 2026 for repair and electrification work at Misawa Air Base (Project QKKA 222447), a $3.15 million delivery order in September 2025 to construct a Readiness Condition Code Placard vehicle maintenance facility at Misawa Air Base, a $1.8 million delivery order in March 2024 for switching station repair at Misawa Air Base, and a $1.2 million definitive contract in December 2023 from Navy Installations Command for sand blast booth replacement at Naval Air Facility Misawa.

Customer concentration is extreme: Pacific Air Forces accounts for 56 awards (93% of combined potential value: $1.39 billion) and Navy Installations Command for 51 awards ($9.8 million), representing 92% of all awards by count. The remaining customer base—the Army, Air Force Headquarters, and Defense Logistics Agency—together accounts for less than 1% of dollar value. Work is performed entirely in Japan at Misawa Air Base, Naval Air Facility Misawa, Draughon Range, Hachinohe Fuel Port, and Shariki Town.

Tanakagumi's dominant parent vehicle is the Multiple Award Construction Contract - Misawa Air Base 2025-2035, a $990 million IDIQ awarded January 13, 2025, with an ultimate completion date of January 12, 2035. Two prior MACCs (2010-2016 and 2016-2025) carried 20 and 15 task orders respectively. Other parent vehicles include Navy Installations Command indefinite delivery contracts (16 and 12 task orders across two vehicles) and Air Force contracts.

Activity has remained sparse in recent years—3 to 9 awards annually from 2022 to 2025—with only one award in 2026 to date. Within the next twenty-four months, ten awards carrying $11.3 million in combined potential value reach ultimate completion and will face recompete. The 180-award historical portfolio (dating to 1993) totals $1.41 billion in combined potential value, but only $58 million (4% of ceiling) has been obligated, reflecting the vendor's role as a backup contractor on older MACCs and recent concentration on the new 2025-2035 vehicle.
