Japan’s Trucking Crunch

Since April 2024, Japanese truck drivers have been subject to a legal cap of 960 overtime hours a year. The rule was meant to fix one of the country’s harshest working environments, but it also removed slack from a freight system that already ran short of drivers. Japan calls the result the “2024 Logistics Problem”, and its effects now reach shippers, retailers and foreign suppliers alike.

What Changed in April 2024

Japan’s 2019 Work Style Reform law capped overtime for most employees, but truck drivers, doctors and construction workers were given a five-year grace period. That period ended on April 1, 2024. Two sets of rules now apply to drivers:

• Overtime cap — a maximum of 960 overtime hours per year, compared with 720 hours for most other workers.
• Revised working-time standards — total time on duty is limited to 3,300 hours a year in principle (up to 3,400 under a labor-management agreement), with a daily limit of 13 hours that can stretch to 15.
• Longer rest — drivers should get at least 11 consecutive hours off between shifts, and never fewer than 9.

Long-haul routes were hit hardest. A single driver can no longer cover a Tokyo–Osaka–Tokyo round trip on the schedules that were common a few years ago.

Why the Cap Bites

Trucks carry over 90% of Japan’s domestic freight by tonnage, and the driver workforce was already shrinking before the cap took effect. Drivers work markedly longer hours than the national average for lower pay, and the profession is older than the workforce as a whole. Few young people are entering it.

A government study group estimated in 2023 that, without countermeasures, Japan’s trucking capacity would fall short of demand by about 14% in 2024 and by about 34% in 2030. The 2030 figure is roughly 940 million tons of freight that would have no truck to carry it.

These are projections assuming no action. Their main purpose was to push shippers and carriers to change practices before the gap appeared.

How Japan Is Responding

Making shippers share the burden

A central problem is unpaid waiting time. Drivers often wait hours at warehouse docks and then load and unload by hand. Amendments to Japan’s logistics laws, passed in 2024, put obligations on shippers as well as carriers. From April 2026, large shippers must appoint a chief logistics officer and submit plans to cut waiting and loading time. The government’s target is to bring the time a driver spends on each delivery stop down to two hours or less.

Higher freight rates

The transport ministry raised its “standard freight rates”, a reference tariff for negotiations between carriers and shippers, by about 8% on average in 2024. It also allowed carriers to charge separately for waiting and loading work. Small carriers, which make up most of the industry, have long struggled to pass costs on to large customers.

Moving freight off the road

• Modal shift — the government aims to roughly double freight volumes carried by rail and coastal shipping over about a decade.
• Relay transport — long routes are split at midway hubs where drivers swap trailers and return home the same day.
• Double-trailer trucks — 25-meter double-coupled trucks let one driver carry about twice as much on expressways.
• Autonomous trucking — trials of driverless trucks on dedicated lanes of the Shin-Tomei Expressway began in 2025, and an automated freight corridor between Tokyo and Osaka is under study.

Foreign drivers

In 2024 Japan added road transport to its Specified Skilled Worker visa program, opening truck, bus and taxi driving to foreign workers for the first time on a meaningful scale. Drivers still need a Japanese license and language skills, so the inflow is expected to be gradual.

Effects on Business So Far

The feared delivery collapse did not happen in 2024, partly because freight demand was soft and partly because companies prepared. Change has still been widespread:

• Some carriers have stretched next-day delivery to two days for distant regions.
• Competing manufacturers, such as food and beverage makers, have started sharing trucks and warehouses.
• Retailers and convenience store chains have cut delivery frequency to stores.
• Parcel carriers such as Yamato Holdings have raised prices and reworked their networks.

Labor costs keep rising, and logistics is becoming a board-level issue at Japanese companies rather than a back-office cost.

What It Means for Overseas Partners

• Exporters to Japan — expect longer domestic lead times and higher inland freight costs. Palletized, standardized shipments that load quickly are increasingly favored by importers.
• Automation vendors — demand is strong for warehouse robotics, automated storage (a field led by companies such as Daifuku), dock scheduling software and load-matching platforms.
• Investors — logistics real estate near relay hubs, rail terminals and ports stands to benefit from the shift away from single-driver long-haul trucking.
• Labor and training providers — the new visa category creates demand for driver training, licensing support and housing services for foreign drivers.

Conclusion

The overtime cap did not cause Japan’s driver shortage. It made an existing problem impossible to ignore. Over the rest of the decade, the main question is whether shippers, carriers and policymakers can raise productivity faster than the driver pool shrinks. For overseas companies selling automation, data tools or logistics capacity, that pressure has opened a sizeable market.
