Business Details
Comprised of two reportable segments: Marine Engine Related (marine diesel engines and maintenance) and Land-based Engine Related (land-based diesel engines, emergency power generators, etc.). The shipbuilding and shipping industries are the main customers, with supply through domestic manufacturing (Moriyama and Himeji plants) and a domestic and overseas sales network. This core business accounts for approximately 94.7% of consolidated net sales. The export ratio for marine engines is high at 63.2%, with Asia accounting for 71.9% of exports.
Recent Overview
Revenue declined but profit improved; order backlog expanded significantly, up more than 51% year-on-year
In FY2026 (ending March 2026), sales of small-to-medium-sized engines for bulk carriers and tankers grew, and maintenance-related sales continued to perform solidly. However, division sales were ¥83,375 million (down 1.3% year-on-year) due to a decline in average selling price resulting from a shift in the sales mix toward small-to-medium-sized engines. Segment profit improved to ¥11,458 million (up 4.8% year-on-year). On the order front, the successful capture of demand for large container ship engines and dual-fuel engines resulted in a marine engine order backlog of ¥102,284 million (up 53.6% year-on-year), with the division's total order backlog expanding significantly to ¥113,500 million (up 51.2% year-on-year). Investment to expand production facilities for next-generation fuel-compatible engines at the Himeji plant is also ongoing.
Key Products
Growth Drivers
- Solid trend in demand for new vessels supported by the continued high level of order backlogs in the shipbuilding industry (order backlogs at domestic and overseas shipyards remain elevated)
- Significant increase in orders for large container ship engines and dual-fuel engines (marine order backlog up 53.6% year-on-year to ¥102,284 million)
- Expanding demand for next-generation fuel vessels (methanol- and ammonia-compatible) driven by aging vessel replacement and environmental regulation compliance
- Continued solid trend in maintenance-related sales (stabilization of after-sales service revenue for ocean-going vessels)
- Expansion of production capacity for next-generation fuel-compatible engines through the Himeji plant expansion (expenditure on acquisition of property, plant and equipment of ¥11,372 million, approximately 1.8x the previous period)
- Expected significant increase in the number of commercial engines sold and rise in average selling price due to an increase in large and dual-fuel engines in the next fiscal year
Risks
- Risk of declining average selling price and downward pressure on revenue due to an increasing sales mix ratio of small-to-medium-sized engines (for bulk carriers and tankers)
- Expected decline in maintenance-related sales in the next fiscal year (due to heightened uncertainty in the shipping market and foreign exchange rates)
- Risk of stagnant gross profit due to intensifying competition in engine sales
- Increased fixed cost burden due to higher personnel expenses and expanded growth investment (growth investment exceeding depreciation expenses is planned to continue in the next fiscal year)
- Risk of fluctuation in maritime logistics demand due to US trade policy (tariff increases) and geopolitical risks
- Risk of delays in the development and commercialization of next-generation fuel-compatible engines (timing of market introduction of methanol- and ammonia-compatible engines)
- Risk of increased costs due to soaring raw material prices and foreign exchange fluctuations
- Expansion of working capital burden due to an increase in inventories (up ¥4,685 million from the end of the previous period)
