Eneos Sun-Energy Corporation

Eneos Sun-Energy Corporation, a Japan-based for-profit petroleum supplier, supplies automotive gasoline, fuel oil, and aviation turbine fuel to the U.S. Department of Defense as a prime contractor under open competition, with all 628 federal awards directed to the Defense Logistics Agency Energy for delivery to military installations throughout Japan.

Eneos Sun-Energy Corporation is headquartered in Tokyo, Japan (5 Chome-2 Shinbashi, Minato City, 105-0004) and operates as a corporate entity with for-profit status. The vendor competes exclusively full-and-open with no set-aside designations across its entire federal footprint. The company holds no SBA certifications and carries no minority, women-owned, or disadvantaged business designations.

The company's federal capability is narrowly concentrated: delivering petroleum products to support U.S. military energy logistics in the Asia-Pacific region. Representative prime work includes a $17,911.07 fixed-price-with-economic-price-adjustment delivery order awarded November 25, 2025 by DLA Energy for automotive gasoline (ultimate completion December 31, 2025); an $18,093.16 delivery order for automotive gasoline awarded February 14, 2026 (ultimate completion March 31, 2026); and a $12,054.52 delivery order for automotive gasoline awarded January 19, 2026 for delivery through February 28, 2026. All work is performed in Japan under fixed-price contracts with monthly economic price adjustments tied to Platts Japan escalators.

Customer concentration is absolute: the Defense Logistics Agency Energy accounts for 100 percent of awards (628 total) and 100 percent of combined potential value ($115.5 million). The vendor has no identified subcontract work or involvement with other federal agencies. Awards per year have declined substantially—from 133 in 2022 and 117 in 2023 to 104 in 2024, with only four awards in 2025 and four in the first quarter of 2026 (as of March 13, 2026). The most recent award data spans from December 2019 through March 13, 2026.

Eneos Sun-Energy Corporation holds two active indefinite delivery contracts (IDCs) with DLA Energy. The primary vehicle, SPE60521D1001, awarded November 3, 2020, carries a $32,354,034.66 ceiling with an ultimate completion date of July 31, 2024, and has supported 525 task orders valued at $45.9 million combined potential value. A newer single-award IDC, SPE60524D1006, was awarded September 13, 2024, with a $123,341.08 ceiling extending through June 30, 2029; it has generated eight task orders valued at $107 thousand combined potential value. A third vehicle, SPE60520D1001, has supported 91 task orders valued at $4.7 million. All delivery orders under these IDCs are structured as fixed-price with economic price adjustment, with no subcontractors involved.

Work performance is geographically confined to Japan, with deliveries to Yokota Air Base, Kadena Air Base, Camp Courtney, Camp Kinser, and subordinate Navy and Army facilities. Awards are categorized under NAICS 324110 (Petroleum Refineries) and PSC codes for Fuel Oils (426 awards) and Liquid Propellants and Fuels, Petroleum Base (202 awards). Eneos Sun-Energy operates with zero subcontract exposure and holds no parent vehicle seats beyond its DLA Energy IDCs. The vendor has no teaming relationships, no involvement in defense technology or IT modernization, and no exposure to civilian agencies outside the Department of Defense. The company's role is exclusively as a fuel supplier to support U.S. military operational readiness in Japan.
