Introduction
The 620 pickup refers to a mid‑size commercial pickup truck produced by Hino Motors, a Japanese manufacturer of trucks and buses. Introduced in the early 1970s, the 620 pickup was part of Hino’s 600 series and was marketed under the model designation 620 or 620-2 in various markets. It was designed to provide a versatile platform for small‑to‑medium freight operations, featuring a sturdy chassis, a robust diesel engine, and a range of cab and bed configurations. The vehicle found widespread use in Japan and several export markets, serving roles that ranged from local delivery to industrial logistics.
History and Background
Development and Design Philosophy
During the late 1960s, Hino Motors sought to expand its commercial vehicle lineup to compete with both domestic and foreign manufacturers. The company identified a market segment for a mid‑size pickup that could bridge the gap between light commercial trucks and larger heavy‑duty models. The result was the 620 pickup, a vehicle built on the same chassis architecture as the earlier 600 series but with upgraded powertrain options and enhanced payload capacity.
Design efforts focused on achieving a balance between durability, ease of maintenance, and operational efficiency. Engineers prioritized a robust suspension system, a high‑torque diesel engine suitable for urban and rural use, and cab ergonomics that could accommodate a single operator or a driver‑assistant setup. The vehicle was also intended to be easily adaptable to regional regulatory requirements, which facilitated its export to markets outside Japan.
Production Timeline
The first 620 pickup units rolled off the production line in 1973. The initial batch featured a 6.3‑liter inline‑four diesel engine and a manual six‑speed transmission. Over the next decade, Hino introduced several revisions to improve fuel economy, emission compliance, and driver comfort. Production continued until 1986, when the model was succeeded by the Hino 620‑6 series, which incorporated a new engine family and modernized cab design.
Market Introduction
In Japan, the 620 pickup was initially sold under the brand name “Hino 620” and quickly gained popularity among small businesses and municipal fleets. By the late 1970s, the vehicle was also offered in the United Kingdom, where it was marketed as a compact yet capable pickup suitable for trade and construction. In the United States, the model was sold under the “Hino 620” badge and found a niche among specialty commercial operators who required a reliable yet relatively small truck for city logistics.

Cab and Ergonomics
The standard cab accommodated one driver, while the extended cab variant could seat two occupants. The seating arrangement featured a reclining driver’s seat with adjustable lumbar support, a steering column with a torque‑compensated wheel, and a control panel that grouped essential gauges (speedometer, tachometer, fuel gauge, temperature gauge) within a 30‑degree view. In later model years, a small rear seat and storage compartments were added to increase passenger capacity and storage flexibility.
Fuel Efficiency and Emissions
Early models of the 620 pickup, equipped with mechanical injection, exhibited a fuel consumption of approximately 9.5 liters per 100 km under mixed driving conditions. As emission standards tightened in the 1980s, Hino introduced electronic injection and a turbocharger on certain variants, which improved fuel economy by 10% and reduced particulate emissions by roughly 20%. The vehicle remained compliant with the Japanese emission standards of the era, allowing continued domestic production.
Variants and Configurations
Cab Options
- Standard Cab – single driver seat, no rear seating
- Extended Cab – driver seat plus rear passenger seat

- Box Truck – a fully enclosed cargo body suitable for sensitive goods
- Dump Body – a rear‑loaded dump body used by construction firms for aggregate and gravel transport
- Flatbed – a flatbed with adjustable hydraulic leveling system for carrying oversized loads
- Refrigerated Unit – a climate‑controlled cargo area for perishable goods
Production and Market Presence
Domestic Market
Within Japan, the 620 pickup achieved steady sales figures, averaging 4,000 units annually in the mid‑1970s and peaking at 5,200 units in 1980. The model was favored by a variety of domestic users, including small‑scale manufacturers, retail distributors, and local government agencies. Its compact size and strong low‑speed torque made it particularly suited for densely populated urban environments where maneuverability was critical.
Export Markets
United Kingdom
Hino’s 620 pickup entered the UK market in 1976, positioned as a “compact” pickup that could handle both street‑level delivery and light construction tasks. In the UK, the vehicle was offered with a 4‑wheel drive option to cater to rural and mining operations. By 1984, sales of the 620 pickup in the UK had slowed as newer models with advanced safety features entered the marketplace.
United States
In the United States, the 620 pickup was sold primarily to niche operators, such as specialty delivery companies, small trucking fleets, and municipal services. The model was available with both manual and automatic transmissions, providing operators with flexibility in choosing a transmission that matched their workload requirements. U.S. production figures for the 620 pickup were modest, with an annual output of around 1,200 units during the peak export years.
Other International Markets
Beyond the UK and the United States, the 620 pickup was marketed in several Southeast Asian and Middle Eastern countries. In these markets, the vehicle was often re‑branded under local dealership agreements, yet retained the core mechanical characteristics that defined the Hino 620 series. Export volumes varied significantly from one country to another, with the majority of units shipped to Japan and the UK.
Legacy and Impact
Operational Reliability
The 620 pickup’s chassis and engine design were noted for their mechanical simplicity and ease of repair. Maintenance crews could service key components such as the injection pump, turbocharger, and leaf springs without specialized tooling. This reliability contributed to a long service life for many vehicles in fleet operation, with some units exceeding 200,000 km before replacement.
Influence on Later Models
Technologies pioneered in the 620 pickup – particularly the transition from mechanical to electronic injection and the integration of a four‑wheel drive system – informed the design of subsequent Hino models. The 620‑6 series, introduced in 1986, incorporated a new 6.7‑liter inline‑four diesel engine and a modernized cab that emphasized driver safety and visibility. Many of the design principles from the 620 pickup, such as modular bodywork options and adaptable drive configurations, were carried forward into the broader Hino commercial vehicle lineup.
Collector Interest
In recent years, vintage automotive collectors have expressed interest in early 620 pickup models due to their historical significance and relatively rare production numbers outside Japan. Restoration efforts often focus on preserving the original mechanical injection pump, maintaining the vintage appearance of the cab, and retaining the original alloy wheels. Museums in Japan and the UK have displayed the vehicle as part of exhibitions that explore post‑war automotive development in Japan.
Related Models
While the 620 pickup stands as a distinct model, it shares several developmental ties with other Hino commercial vehicles. Key related models include:
- Hino 600 – the predecessor that introduced the ladder frame and mechanical injection engine technology
- Hino 620‑6 – the successor that introduced electronic injection and an improved cab design
- Hino 700 series – a heavier‑duty truck that built upon the chassis architecture of the 600 series but offered higher payload capacities
These vehicles demonstrate a clear evolutionary path within Hino’s commercial fleet offerings, reflecting the company’s emphasis on incremental engineering improvements.
