Japan Truck Sales Fall 0.5% in First Half of FY2026

Japan Truck Sales Slip Below Previous-Year Level

Japan medium- and heavy-duty truck sales reached 36,539 units from April through September 2026, down 0.5% year-over-year and marking the first decline below the previous year's level in four years. The market covers trucks with a payload capacity of 4 tons or more. The modest overall decrease masks different trends by vehicle category and manufacturer, with heavy-duty truck demand strengthening while medium-duty truck sales weakened. The period also showed signs of recovery in supply capacity and renewed model activity, helping some manufacturers increase deliveries. These developments have shifted the market closer to sales levels recorded two years earlier.

Hino and Mitsubishi Fuso Increase Sales

Hino Motors, Ltd. sold 9,876 units during the period, representing a 6.3% year-over-year increase. Mitsubishi Fuso Truck and Bus Corporation delivered 7,338 units, up 25.2% year-over-year, with heavy-duty trucks contributing particularly to the increase. The stronger results came as manufacturers benefited from updated model launches and improving supply capacity. Hino had also resumed shipments of heavy-duty vehicles equipped with a 13-liter engine in December 2025 after its certification misconduct scandal. The renewed availability of these vehicles supported its return to higher delivery levels during the latest reporting period.

Isuzu Remains Market Leader Despite Decline

Isuzu Motors Limited remained the leading manufacturer in Japan, holding a 38.0% market share despite a 14.1% year-over-year decline in sales. The company sold 13,894 units during the April-to-September period. Its decline contrasted with the gains recorded by several competitors, changing the balance of manufacturer performance within the market even as Isuzu retained the top position. The results indicate that overall market demand was not evenly distributed across manufacturers. Updated products, vehicle availability and differences in heavy-duty and medium-duty exposure contributed to the contrasting sales outcomes among major truck manufacturers.

Heavy-Duty Trucks Gain While Medium-Duty Sales Fall

Sales performance varied significantly by truck category. Heavy-duty truck sales increased 5.1% year-over-year to 27,002 units, supported by stronger deliveries from manufacturers whose main heavy-duty models gained momentum. In contrast, medium-duty truck sales fell 13.4% year-over-year to 9,537 units. UD Trucks Corporation, whose main heavy-duty trucks and tractors recorded increases, sold 5,431 units, up 0.8% year-over-year. The category split shows that the overall 0.5% market decline was driven primarily by weaker medium-duty demand, while stronger heavy-duty sales helped limit the scale of the decline across Japan's medium- and heavy-duty truck market.

Industry Impact & Outlook

Japan's medium- and heavy-duty truck market is entering a mixed phase in which stronger heavy-duty demand is offsetting weaker medium-duty sales. The contrasting manufacturer results suggest that product updates and vehicle availability remain important competitive factors as supply conditions improve. For Japan's truck industry, the return of several manufacturers to stronger delivery levels could intensify competition, particularly in the heavy-duty segment. The next market trend will depend on whether improving supply capacity and updated models can sustain heavy-duty momentum while manufacturers address the decline in medium-duty demand. The market's first year-over-year decline in four years makes this category shift particularly significant.
