Company history

Hino traces back to Tokyo Gas and Electric Industry, founded in 1910, which in 1918 built one of Japan’s first domestically made trucks — a two-tonne machine — and helped seed the country’s fledgling motor industry. In 1937 its automobile arm was folded into Tokyo Motors (later Isuzu), and in 1938 that firm laid out a vast plant at Hino, west of Tokyo, to mass-produce army tanks. A quirk of wartime subsidy law forced the works loose: one company could not draw both the auto-manufacturing subsidy and the army’s protected-vehicle subsidy, so in 1942 the Hino plant was spun off as Hino Heavy Industry, with the state’s Wartime Finance Corporation taking 80% of its shares.

Defeat in 1945 halted tank production overnight, and layoff notices went to some 7,000 workers. The roughly 300 who stayed restarted the firm and turned the diesel-engine and chassis skills built for tanks toward civilian trucks and buses — the pivot that made Hino a commercial-vehicle maker. Renamed Hino Diesel Industry, it listed on the Tokyo Stock Exchange in 1949 and in 1953 completed the Blue Ribbon, Japan’s first underfloor-engine bus.

Then came a costly detour. On the strength of a 1953 licensing tie-up with Renault, Hino built passenger cars and, from 1961, its own Contessa. But its dealer network had been assembled around commercial-vehicle buyers, and passenger sales never took hold. In October 1966 Hino signed a business alliance with Toyota, withdrew from passenger cars and resolved to concentrate on trucks above 11 tonnes gross weight; the Hamura plant, planned for cars, was turned over to building Toyota models on contract. That bargain — surrender the passenger market, lean on a giant parent, specialise in heavy trucks — would frame Hino’s course for the next half-century.

Freed to specialise, Hino went on the attack. In 1974 it launched “Operation D,” a drive for 35% of Japan’s heavy-truck market. Its rival Isuzu, then the domestic leader, had poured resources into scaling up passenger-car output and left its truck business relatively starved of investment; Hino pushed into the gap with new models and a hard sales campaign, overtook Isuzu and held the No. 1 domestic share in heavy trucks for decades to come.

Growth abroad ran in parallel. Building on an early Thai venture, Hino set up local operations across South-East Asia — the Philippines in 1975, Indonesia in 1982 — and entered North America in 1994, while a new plant at Nitta in Gunma (1980) expanded output at home. It was the pattern of a truck maker steadily widening its map even as its home market matured.

Maturity had its price. When domestic truck demand slumped, Hino fell into the red in the year to March 1999 and shed about 300 workers through voluntary retirement — a warning that a single-market specialist was exposed to its home cycle, and a prelude to the closer embrace of Toyota that followed.

In August 2001 Toyota took up a third-party share allotment and made Hino a consolidated subsidiary, steadying its footing after the losses of the late 1990s. Tighter emissions rules then drove a wave of fleet renewal, and in the year to March 2004 Hino’s sales topped $9.2B (¥1tn) for the first time. The group role sharpened: Hino built Toyota-badged vehicles on contract while pushing its own trucks into China and the United States through new engine and manufacturing ventures.

The boldest move was to leave home. In 2011 Hino announced it would close the founding plant at Hino, Tokyo — the works that had given both the company and the city their name — sell the 300,000-square-metre site, and shift production to a new plant at Furukawa in Ibaraki. The roughly $626.7M (¥50bn) investment opened in October 2017 as the group’s mother plant, tying design to manufacturing for about a 20% gain in efficiency and anchoring parts supply to Hino’s overseas lines.

Those overseas lines kept widening — across Thailand and Indonesia, into the Middle East and Latin America — and in 2019 Hino broke ground on a new truck plant in Thailand. By the start of the 2020s it stood as the Toyota group’s commercial-vehicle arm, its fortunes bound to heavy diesel trucks at home and across Asia.

The foundation proved rotten. Between 2003 and 2022 — some twenty years — Hino had falsified emissions and fuel-economy data in its engine-certification filings, a deception that surfaced in stages: first on North American engines in 2020, then, in March 2022, on domestic ones. The tainted engines spanned Hino’s range, from its heaviest trucks down to light models. Shipments were halted and vehicles recalled worldwide, huge certification-related charges followed, and Hino sank to net losses for three straight years.

The parent stepped back. Toyota signalled it would end its support, leaving Hino to find its own way out, and in May 2023 the company announced a merger with Mitsubishi Fuso Truck and Bus, the Daimler Truck subsidiary. But with Hino’s losses still unsettled Daimler turned cautious, and in February 2024 the talks were shelved indefinitely; the same year Hino announced the closure of a U.S. plant and pulled back in North America. Two decades of concealed fraud had put Hino’s very governance — and its ability to survive as an independent heavy-truck maker — in question.

The rescue, when it came, was a change of ownership. In June 2025 Toyota and Daimler Truck signed a definitive agreement to revive the merger: a new listed holding company, ARCHION, in which each will hold 25%, is to launch in April 2026 with Hino and Mitsubishi Fuso beneath it — and Hino, once a roughly 50%-owned Toyota subsidiary, will be delisted. Under the language of a merger of equals the share ratio leans toward Fuso, and Hino’s president is set to move to the role of technology chief. A single failure had reached past the balance sheet to the company’s independence itself.
