About Hosei Co., LTD.
Hosei Co., LTD., a Japan-based international for-profit organization headquartered in Sasebo, Nagasaki, serves as a prime contractor delivering ship repair, naval equipment supply, and utilities operation and maintenance services to U.S. Navy commands in the Western Pacific region. The vendor competes without set-aside designation across all federal contracts, competing openly in the full-and-open market.
Hosei's footprint centers on ship repair and maintenance work for Navy surface combatants, amphibious assault vessels, and mine countermeasures ships, with secondary focus on utilities infrastructure management at Navy installations in Japan. Concrete capability examples include a $575 million delivery order (awarded August 2023) for procurement and installation of an LPD-18 ship diesel generator engine crankshaft under the Naval Sea Systems Command Basic Ordering Agreement, a $1.7 million delivery order (awarded February 2023) for controllable pitch propeller system valve rod and propeller hub installation on an LSD-47 vessel, and a $3.8 million delivery order (issued October 2025) for recurring second-option-period utilities operation and maintenance work across multiple Navy installations in Japan under the Navy Installations Command IDIQ. Representative ship repair work spans propulsion system repairs, structural restoration, piping and valve replacement, deck preservation, HVAC systems overhaul, and specialized equipment installation on San Antonio-class amphibious transport docks (LPD-17/18), Whidbey Island-class dock landing ships (LSD-47/48), Avenger-class mine countermeasures ships (MCM-7/9/10/14), and America-class amphibious assault ships (LHA-6/7).
Hosei's customer concentration reflects heavy Navy operational focus. The Department of the Navy Installations Command leads by potential value at $223.2 million across 123 awards (57% of combined potential value), while the Naval Facilities Engineering Command accounts for $98.8 million across 192 awards. Naval Sea Systems Command drives award volume with 1,575 orders totaling $51.9 million combined potential value, and U.S. Pacific Fleet Forces placed 1,185 orders worth $16.4 million combined potential value. These five Navy entities represent 99% of the vendor's recent award count. The two largest customers diverge sharply on ranking — the Installations Command dominates dollars while NAVSEA and Pacific Fleet Forces dominate order frequency with thousands of smaller-value maintenance and repair task orders.
Hosei holds two significant parent vehicles anchoring its federal posture. The Navy Installations Command awarded a single-award IDIQ contract (N4008423D6301) on September 1, 2023, with a $124 million ceiling through October 31, 2028, covering base operations support and utilities operation and maintenance at Navy installations throughout Japan, including electrical, gas, water, steam, sewage, compressed air, and saltwater systems management, plus facility and port operations support. Naval Sea Systems Command issued a Basic Ordering Agreement (N6264922G0006) on October 1, 2022, effective through September 30, 2027, with no specified ceiling, authorizing firm fixed-price delivery orders for naval equipment, component supply, and ship repair and maintenance work across multiple vessel classes in the Western Pacific. Beyond these two vehicles, Hosei places task orders against five additional government IDIQs and BOAs, with the top three unnamed vehicles generating 647, 528, and 321 task orders respectively, indicating deep utilization across Navy maintenance and repair infrastructure.
Activity has remained consistent in recent years—95 awards in 2022, 53 in 2023, 68 in 2024, and 57 in 2025—with recent award velocity at 16 awards year-to-date in 2026, tracking roughly on pace. The recompete cliff is modest: only 19 awards with ultimate completion dates within the next twenty-four months, carrying combined potential value of $1.2 million, suggesting limited near-term recompete exposure relative to the vendor's $391 million combined potential value footprint.
Hosei subcontracts under five Crowley Government Services prime contracts, all related to operation and maintenance of U.S. Navy vessels including government-owned maritime prepositioning force ships and Navy-operated sealift vessels (USNS-class). Sub-awards span vessel maintenance, preservation work, bilge cleaning, hydraulic system service, hoist installation, and air handling unit repairs, typically valued under $100,000 per sub-order. Crowley serves as Hosei's primary teaming vehicle for direct Navy vessel operations support outside the Sasebo installation footprint.
The vendor's award portfolio concentrates heavily in ship building and repair (2,603 awards under NAICS 336611) and facilities support services (210 awards), with minor exposure to electric power distribution and water transportation support. Across primary PSC coding, Non-Nuclear Ship Repair (West) accounts for 2,696 awards, utilities operations 133 awards, and housekeeping-facilities operations support 109 awards. All awards carry firm fixed-price pricing with no set-aside designation, reflecting open-market competition across the federal portfolio.
Hosei has held federal contractor status since August 2005, establishing nearly two decades of continuous Navy partnerships in the Western Pacific theater. The vendor registers in SAM.gov and maintains active federal contracting authority. With 3,155 prime awards against 7 sub-awards, Hosei operates almost exclusively as a prime contractor, positioning it as a direct Navy strategic partner rather than a subcontractor-dependent vendor.
