Company history

In January 1961 Itochu split off part of its oil subsidiary to create Itochu Fuel, capitalised at ¥60 million, for a single purpose: to sell the products of the refinery Itochu and Nippon Mining had just built at Mizushima in Okayama. Japanese oil in those years was organised exactly this way — mining companies built refineries along the Pacific coast through the late 1950s, and each group’s sales company distributed to customers in its territory. Itochu Fuel was the group’s outlet, and its size was set not by its own effort but by the parent’s order book. That relationship held for forty years.

The corporate shell was older and stranger than the business: the formal date of incorporation is April 1948, and the entity was a dormant chemicals company that took the Itochu Fuel name only in 1976, absorbing the earlier operating company in 1977 in a reorganisation aimed at listing. The shares went onto the second sections of the Osaka and Tokyo exchanges in February 1978 and were promoted to the first section in September 1979; the head office moved from Osaka to Tokyo in 1983. None of this changed the substance — Itochu held a clear majority, and both supply and sales agency ran through the parent.

Where the company did build something of its own was in LPG. From the mid-1960s it absorbed regional gas distributors one after another across Honshu and Kyushu — Oita in 1965, then new companies in Hiroshima, Saitama and Mie — and in 1970 bought into industrial gases as well. Japan’s LPG market was a scatter of small local dealers; a trading-house subsidiary could assemble them into a national network in a way no local firm could.

In July 1990 Itochu Fuel took over the business and staff of Itochu Oil, the parent’s domestic petroleum sales subsidiary. It was a single line in the corporate chronology with no disclosed price, but it inverted the company’s position: the vessel built to absorb refinery output was now receiving the parent’s selling function itself, and all of the Itochu group’s domestic oil sales ran through one window.

Acquisitions continued through the decade — a wholesaler in reorganisation proceedings in 1997, a tyre and car-accessory retail business spun out in 1998, further oil-sales purchases in 1999 and 2000 — but consolidated revenue stayed in the hundreds of billions of yen and the company’s standing inside the group did not move. It was still the parent’s sales subsidiary.

What forced the question was the parent’s own crisis. Itochu carried ¥5.2 trillion of interest-bearing debt at March 1998 after the property bubble, and under president Uichiro Niwa wrote off ¥395.0 billion of extraordinary losses in one pass in the year to March 2000. In the rebuilding that followed, Itochu demanded that non-core businesses be cleared out and that subsidiaries earn on their own account — which, for a company whose revenue was an artefact of its parent’s order flow, meant finding a source of profit it actually owned.

In July 2001, on its fortieth anniversary, the company renamed itself Itochu Enex and renamed eighteen consolidated subsidiaries to match — “ENEX” a coinage from energy, end consumer and ecology, plus “next.” It was a declaration of a shift from fuel trader to energy trader made before any of the substance existed: the company handled neither power nor heat at the time. In April 2004 it scrapped the old regional branch structure for product-based divisions — oil, LPG, industrial energy, car life — so that each business could be measured on its own profit, an idea borrowed from the parent’s division-company system.

The substance then arrived over the following decade. Acquisitions in LPG distribution and car servicing ran from 2005 to 2008; in the second half of 2008 Itochu transferred its petroleum trading and logistics businesses down by company split, and consolidated revenue passed ¥1 trillion in the year to March 2010. In February 2011 the company entered electricity retailing — five years before Japan’s market was fully liberalised — added industrial heat and power supply the same year, and district heating in 2012. The name had been changed first; the business caught up to it in about ten years.

Adopting IFRS from the year to March 2014 then changed how the company was read. Under Japanese GAAP that year’s revenue was ¥1,506.6 billion; under IFRS it was ¥966.0 billion, because agency transactions in which the trader carries no inventory risk are reported net rather than gross. Profit was unaffected — but the difference of some ¥600 billion moved the company’s public identity from “a wholesaler with revenue above ¥1 trillion” to “an energy trader earning about ¥10 billion.” That was the more honest description, and it framed everything that came next.

In May 2014 Itochu Enex paid about ¥6 billion for 51.95% of Osaka Car Life Group, taking control of Nissan Osaka Sales — one of the largest Nissan dealer groups in the country and the only one in Osaka Prefecture. Until then its “car life” business had meant selling petrol and diesel at its own service stations. With a dealer network the company could hold the whole sequence inside the group: sell the car, fuel it, service it, sell the replacement. Osaka Car Life’s 107 outlets were linked to roughly 150 group stations, with fuel discounts and washes for buyers.

From April 2018 the company reorganised into four segments — car life, home life, industrial business, and power and utilities — with car life as the core. In the year to March 2019 that segment produced ¥624.3 billion of ¥1,007.1 billion in group revenue, 62% of the total. In parallel the power business was turned into managed assets, with a renewable-energy asset manager acquired in 2017 and an infrastructure fund listed on the Tokyo Stock Exchange in 2019.

Then in May 2024 Itochu Enex, alongside Itochu and the turnaround fund J-Will Partners, acquired WECARS, taking over by company split the roughly 250 used-car outlets of Big Motor, the chain that had collapsed over fraudulent insurance claims. The Itochu group and J-Will paid around ¥40 billion together and sent in some fifty executives, targeting profitability and full ownership within two or three years; the plan is to link those 250 outlets with the group’s 1,566 service stations. Under the ENEX2030 plan set in 2023 the company is aiming at net income above ¥20 billion and ROE above 9.0%; the year to March 2025 delivered ¥17.1 billion and 10.22%, with car life at ¥630.0 billion of ¥924.5 billion in revenue — 68% — and 43% of operating profit. Itochu still holds 55.62%. The receptacle built for a refinery in 1961 now describes itself as an energy trader, and sells cars.
