Iwata Sansho Corporation

Iwata Sansho Corporation, a for-profit Japanese manufacturer headquartered in Oyabe, Yokosuka, Kanagawa Prefecture, supplies industrial equipment, electrical components, and mechanical parts to the U.S. Navy as a direct prime contractor on competitive, full-and-open purchase orders with no set-aside designation. The company operates exclusively as a prime (100% of awards) and competes in an unrestricted vendor pool — no SBA certifications or set-aside posture on the federal side.

Iwata Sansho's federal footprint is highly concentrated. Naval Sea Systems Command (NAVSEA) accounts for 123 of 127 awards (97% of volume, $2.7 million of $2.8 million combined potential value), with three remaining awards split among the Navy's Installations Command, Naval Computer and Telecommunications, and Naval Facilities Engineering Command. All work is performed in Japan under firm fixed-price purchase-order contracts. The vendor supplies a narrow, specialized portfolio of industrial consumables and components: electrical wire and cable (8 awards), winches, hoists, and chain hoists (recurring SKU across multiple years), pneumatic blowers and portable air handling equipment, extension cords with rain-protection fittings, batteries, air cleaners, grease pumps, coupling halves, nut breakers, and grinding equipment. Recent awards include a $94,027 purchase order for electrical wire (November 2024, completion March 2025), a $48,735 order for quick-coupling halves (June 2024, completion November 2024), and three orders placed in spring 2026 for spot coolers ($21,835), outdoor extension cords with rain caps ($18,612), and a portable pneumatic blower ($18,612), all completing between June and July 2026.

Activity has contracted materially. The vendor averaged 6 awards per year from 2022 to 2023, then fell to 2 orders in 2024, recovered slightly to 3 in 2025, and sustained 3 year-to-date in 2026. Combined potential value sits at $2.8 million — all dollars obligated — reflecting the small-ticket, repetitive nature of naval supply orders. The vendor has maintained a registered federal contractor presence since 2005 and carries an established track record with NAVSEA spanning twenty years. Iwata Sansho has no subcontract relationships within the federal footprint and operates as a foreign-source prime exclusively, meaning it does not appear as a teaming partner or sub on other contractors' proposals. The business is a specialized component supplier to naval operations, not a systems integrator, architect, or services provider — competitive positioning in procurement is based on availability, pricing, and delivery of specific industrial SKUs from Japan.
