Business Details
A single reportable segment engaged in the design, manufacture, repair, and sale of marine internal combustion engines and parts, as well as related businesses. Main customers are in the domestic coastal shipping and shipbuilding industries, with domestic sales accounting for the majority of revenue, while exports are also conducted to Asian regions such as Singapore and Taiwan. In FY2026 (ending March 2026), net sales increased to ¥8,333 million (up 6.2% year on year) due to higher sales of marine internal combustion engines (main engines) and parts & repair work, but the company recorded an operating loss due to deterioration in the cost ratio.
Recent Overview
Sales increased but the cost ratio deteriorated, resulting in an operating loss; gains from share sales secured a net profit for the period
In FY2026 (ending March 2026), net sales rose to ¥8,333 million (up 6.2% year on year) due to increased sales of marine internal combustion engines (main engines) and parts & repair work. However, the company was unable to fully pass on rising costs for raw materials, purchased goods, and various expenses to selling prices, causing the cost ratio to deteriorate significantly and resulting in an operating loss of ¥188 million (compared with operating income of ¥19 million in the prior period). Net income of ¥186 million was secured through the recognition of extraordinary gains of ¥215 million from the partial sale of held shares. The order backlog at period end remained at a high level of ¥6,109 million (up 48.9% year on year). For FY2027 (ending March 2027), the company plans net sales of ¥9,000 million, operating income of ¥20 million, and ordinary income of ¥140 million.
Key Products
Growth Drivers
- A recovering trend in inquiries for newbuild vessels, driven by the progressing aging of vessels in coastal shipping and the need to comply with stricter environmental regulations
- Sustained solid construction demand in the international shipping sector (mainly large vessels), supported by a weak yen
- An increasing trend in inquiries for overseas projects, mainly in the Asian region
- Improved visibility of future sales due to a period-end order backlog of ¥6,109 million (up 48.9% year on year)
- Strengthening of the revenue base complementing the main engine business through expanded orders for parts & repair work
- Cultivation and expansion of new businesses such as the purification equipment business and the BDF manufacturing and sales business
- Strengthened competitiveness through the development of next-generation fuel engines, new low-fuel-consumption engines, and autonomous navigation ship systems
Risks
- Upward pressure on the cost ratio due to persistently high prices for raw materials, purchased goods, and various expenses (difficulty passing on costs to main engine selling prices)
- Risk of continued sluggish sales in the land-based division (industrial and civil engineering machinery, etc.)
- Continued pressure on profitability from external factors such as persistently high prices for materials and equipment and rising procurement costs
- Uncertainty in the international situation due to geopolitical risks such as U.S. tariff policy and Middle East tensions
- Risk of a slowdown in the pace of order accumulation, as orders received declined 18.3% year on year to ¥7,802 million
- Downward pressure on operating income/loss from persistently high selling, general and administrative expenses (¥1,517 million)
