Nihon Kaiyo Sangyo Co.,Ltd.

Nihon Kaiyo Sangyo Co., Ltd., a for-profit Japanese marine-equipment manufacturer based in Shimonoseki, Yamaguchi, supplies specialized naval hardware and rubber marine products to the U.S. Navy as a prime contractor on firm-fixed-price purchase orders, with no subcontract footprint. The vendor is not an SBA-certified small business and does not compete under set-aside categories; one recent solicitation (a submarine-fender repair purchase order awarded February 15, 2026) was designated WOSB/EDWOSB set-aside, but the source does not indicate whether the vendor held that certification at award.

Nihon Kaiyo Sangyo's capability portfolio centers on specialized marine-hardware manufacturing and repair: foam-filled marine rubber fenders, pneumatic fenders, rope reels, oil booms with fasteners, storage containers, pedestals, and submarine-fender counterweight systems with on-site repair labor. Recent representative awards include a $150 thousand Navy Installations Command purchase order (February 15, 2026) for submarine-fender repair and replacement involving removal, pressure cleaning, chain assembly replacement, and reinstallation at Fleet Activities Yokosuka using specialized equipment; a $91 thousand Naval Sea Systems Command purchase order (September 7, 2021) for rope reels; and a $119 thousand Navy Installations Command purchase order (August 17, 2021) for foam-filled marine rubber fenders.

Customer concentration is narrow and Navy-specific: all twelve awards documented in the source went to the Department of the Navy across three customer commands — Navy Installations Command (7 awards, $748 thousand combined potential value), Naval Sea Systems Command (3 awards, $238 thousand), and Naval Supply Systems Command (2 awards, $68 thousand). The vendor has maintained continuous Navy business since at least 2010, with recent activity clustering in 2021 (three awards) and sporadic single-year awards in 2023 and 2026. Combined potential value across the entire twelve-award portfolio is $1.1 million, fully obligated. The vendor operates with no parent-vehicle relationships; all awards are direct purchase orders. Performance occurs in Japan with delivery to Fleet Activities Yokosuka and other Navy installations.
