Kyowa Marine Service Co., LTD.

Kyowa Marine Service Co., LTD., a Japanese for-profit maritime services company based in Okinawa, delivers harbor tugboat and ship-mooring assistance exclusively to the U.S. Department of the Navy as a prime contractor under multiple indefinite delivery contracts, competing on an unrestricted, full-and-open basis with no set-aside designations.

The vendor's entire federal footprint—171 awards totaling $12.7 million in combined potential value across the past two decades—flows through the Military Sealift Command, which accounts for 157 awards (99% of the portfolio by count) and $12 million in combined potential value. Kyowa Marine holds five active IDCs with MSC: the primary vehicle, IDC N6264920D0004 (ceiling $2,196,342.20, running through June 30, 2030), anchors 65 task orders at $2 million combined potential value; the predecessor IDC N6264916D0012 generated 44 task orders at $1.3 million; and three additional legacy vehicles (N6264905D0018, N6264925DG002, N6264915D0010) collectively represent 42 task orders. Delivery orders under the current primary IDC cluster around $22,000 to $48,000 per order, issued at a cadence of roughly 12 to 14 annually in peak years (2023, 2025), with 2026 showing only one award to date as of May 8. Combined obligated dollars across the portfolio stand at $4.5 million (36% of the potential value ceiling), reflecting the recurring, incremental nature of the work.

Kyowa Marine's concrete service scope centers on harbor tug operations at Tengan Pier, Okinawa, supporting vessel movements for named ships including USNS Carl Brashear, USNS Charles Drew, and general naval logistics operations. Services include ship arrival and mooring assistance, ship undocking and departure support, harbor tug services for pushing and holding operations, and occasional translation services. All work is performed in Japan at Tengan Pier, a strategic naval facility in the Indo-Pacific. The vendor must comply with all Japanese laws regarding safety, tugboat licensing, and employee training. Representative recent orders include $24,103.35 (May 8, 2026), $27,474.07 (September 18, 2025), $30,244.45 (September 4, 2025), and $29,551.85 (April 15, 2025) delivery orders—all under the primary IDC.

The vendor's NAICS profile is heavily concentrated in Navigational Services to Shipping (168 of 171 awards), with PSC-level work consistently coded as Transportation/Travel/Relocation—Vessel Towing. Kyowa Marine has maintained a continuous SAM.gov registration since August 2005, establishing itself as MSC's incumbent, sole-source provider at this Okinawa facility. Activity has remained relatively flat—between 10 and 14 awards per year over the past five years—with no recompete cliff signal in the near term given the single underlying IDC structure and the recurrence pattern of small, frequently-issued orders. The vendor holds no parent vehicle seats on government-wide acquisition contracts, GWACs, or civilian agency vehicles; its entire portfolio is Navy-specific and geographically bound to Okinawa operations.
