Keihin Koun Co.,Ltd.

Keihin Koun Co., Ltd. Maritime Operations Division, a for-profit corporate entity based in Yokohama, Japan, operates as a prime contractor providing stevedoring, vessel loading and unloading, and port terminal services to the U.S. Department of Defense at the Port of Yokohama on a full-and-open (non-set-aside) basis. The vendor competes exclusively as a prime — no subcontract footprint — and holds a thirty-year federal award history spanning since 1992.

The vendor's customer base is highly concentrated around military sealift operations in Japan. The Department of the Army accounts for 317 awards (99% of the portfolio) with $8.2 million in combined potential value, of which the Army Materiel Command's Surface Deployment and Distribution Command (SDDC) issued 155 awards valued at $3.4 million — nearly all recurring monthly delivery orders for stevedoring and related terminal services (S & RTS) at Yokohama spanning 2021 through early 2022. The Department of the Navy accounts for six awards, including a December 2025 purchase order from Naval Sea Systems Command for $249.8 thousand to provide warehouse storage and upkeep services in support of USS Blue Ridge, the Seventh Fleet flagship, running through September 2026. Combined potential value across the full portfolio stands at $11.9 million, with $12.9 million obligated (109% of potential), indicating mature execution against ceiling values.

Work is performed entirely in Japan (Yokohama) in support of forward-deployed U.S. naval vessels and military sealift command operations. The vendor's NAICS profile is sharply focused: 346 of 482 awards carry Marine Cargo Handling (NAICS 488320) designation, with 473 awards coded to PSC stevedoring services. The top five parent vehicles are Army and Navy indefinite delivery contracts — IDC N6264901D0015 (206 task orders), IDC N6264914D0005 (103 task orders, $1.7 million combined potential value), IDC HTC71117DR001 (41 task orders, $2.7 million combined potential value), IDC N6264991D0045 (38 task orders), and IDC N6264994D0048 (30 task orders). Recent activity has slowed: the portfolio shows three awards in 2021 and 2022 each, and one award in 2025 (the USS Blue Ridge contract). Only one award ($250 thousand) faces ultimate completion in the next twenty-four months, limiting near-term recompete exposure. The vendor's capability is narrowly specialized in port labor, cargo handling, and vessel operations logistics — a critical but geographically constrained niche supporting U.S. military operations in the Western Pacific.
