A notable feature is the profit contribution from Equity-Method Investments (Japan Marine United, etc.).
Recent Overview
Segment profit expanded significantly, up 113% year on year to ¥35,881 million, driven by a surge in equity-method investment gains
In the "Others" segment for FY2026 (ending March 2026), revenue from external customers saw modest growth to ¥53,254 million (up 5.6% year on year), while segment profit surged approximately 2.1-fold year on year to ¥35,881 million (versus ¥16,829 million in the prior fiscal year). The primary driver was a substantial increase in equity-method investment income to ¥8,644 million (versus ¥5,030 million in the prior fiscal year). Note that, per the correction dated May 25, 2026, the prior fiscal year's (FY2025, ended March 2025) depreciation and amortization figures were reclassified between the Social Infrastructure segment and the Others segment, with the Others segment's depreciation figure revised from ¥1,753 million (pre-correction) to ¥8,041 million. Segment assets declined significantly to ¥259,774 million from ¥349,917 million at the end of the prior fiscal year.
Key Products
Growth Drivers
- Increased profit contribution from equity-method affiliates (JMU, etc.) (FY2026 (ending March 2026): ¥8,644 million, up 71.8% year on year)
- Maintenance and expansion of segment scale through the reclassification of the Urban Development business from the Social Infrastructure segment
- Steady performance in the manufacturing, sale, and services of the inspection & measurement business
