What ENEX does

ENEX Co., Ltd. (株式会社エネックス) is a Japanese specialized logistics company that provides tank-lorry transportation of petroleum products (gasoline, diesel, kerosene, jet fuel, lubricants), liquefied natural gas (LNG), high-pressure gases, and chemical intermediates (methanol, butadiene). Founded in 1964 (with predecessor entities dating to 1961) and headquartered in Shinagawa-ku, Tokyo, ENEX operates the largest LNG tank lorry fleet in Japan and maintains a fleet of more than 1,600 specialized vehicles, including 689 tractors, oil tank lorries/trailers, high-pressure tank lorries/trailers, chemical tank lorries/trailers, and container chassis. In FY2025 the company transported 4,598 thousand KL of petroleum, 992 thousand tonnes of LNG, 261 thousand tonnes of high-pressure gas, 102 thousand tonnes of chemicals, and 1,771 container units, generating ¥20,690 million in revenue.

The company's primary customers are major Japanese energy and utility firms—ENEOS (petroleum order dispatch and oil terminal operations), Tokyo Gas (LNG base operations at Negishi, Sodegaura, and Hitachi), and Tohoku Electric Power (LNG base operations)—with secondary reach into industrial gas/chemical plants and automotive manufacturers (Toyota Motor East Japan). Revenue is generated via transaction-fee billing on transport contracts and managed-services fees for the contracted operation of oil depots, LPG terminals, and LNG bases, including two dedicated ENEOS order dispatch centers (Yokohama, Osaka). The go-to-market is enterprise field sales: long-term B2B contracts executed through nine regional branches and 30+ sales offices strategically co-located within customer facilities, supported by five dedicated safety and LNG handling training centers (Ichikawa, Ibaraki, Kashima, Hachinohe).

ENEX is a privately held, wholly-owned subsidiary of Nippon Oil Transport Co., Ltd. (日本石油輸送) and operates as the group's primary petroleum, LNG, and high-pressure gas transport entity alongside affiliated subsidiaries including Kinki Oil Transport, JK Trans, Kanto Auto Maintenance, and Akita Oil Base Disaster Prevention. The company has grown primarily via intra-group mergers, most recently absorbing New J's Co., Ltd. in April 2025. Capital structure is modest (¥100 million registered capital), and the consolidated combined-transport system integrates road and rail via the parent, positioning ENEX as a structurally embedded, scale-driven logistics provider to Japan's regulated energy supply chain.

Core offering

ENEX provides nationwide tank-lorry transportation of petroleum products (gasoline, diesel, kerosene, jet fuel, lubricants), LNG (liquefied natural gas), high-pressure gases, and chemical products, operating Japan's largest LNG tanker fleet. In addition to core transportation, the company delivers contracted order-receiving and dispatch center operations for fuel oils and lubricants at ENEOS facilities, LNG loading operations at Tokyo Gas bases, and managed operations of oil depots, LPG terminals, and LNG bases for major Japanese energy and utility customers.

Product overview

ENEX operates as a comprehensive logistics company offering specialized transportation services for petroleum products, LNG (liquefied natural gas), high-pressure gases, and chemical products. The company functions as a unified portfolio of services rather than a traditional platform-plus-modules architecture. Core transport offerings include petroleum product transportation using tank trucks, LNG transportation (Japan's largest fleet), and high-pressure gas/chemical transportation. These are complemented by contracted management services for oil depots, LPG/LNG bases, and dispatch operations. A key differentiator is the Group Integrated Transportation system that combines road and rail transport. The company generated ¥20,690 million in FY2025 revenue and maintains the largest LNG tank truck fleet in Japan.
