Business Details
Comprises Toyo Tanso's parent company and domestic subsidiaries. Consolidates domestic manufacturing of isotropic graphite materials, serving as the group's production hub supplying semi-finished products to overseas locations. Manufactures and sells Special Graphite Products (Metallurgical and Electronics Applications... for semiconductor and metallurgical use), General Carbon Products (Mechanical Carbon and Electrical Carbon), and Composite Materials and Other Products (SiC-coated graphite, C/C composites, graphite sheets). In Q1 FY2026 (ending December 2026), sales to external customers of ¥5,511 million accounted for 52.1% of the group total, making it the largest segment.
Recent Overview
Both sales and profit deteriorated substantially year-on-year due to a sharp decline in semiconductor applications.
In Q1 FY2026 (ending December 2026), sales in the Japan segment were ¥5,511 million (down 12.3% year-on-year), and operating profit was ¥782 million (down 51.1% year-on-year). This was mainly due to a substantial decrease in semiconductor applications amid market adjustment. On the other hand, metallurgical applications such as industrial furnaces and electrical discharge machining electrodes performed steadily. Special Graphite Products overall declined only 0.6% year-on-year, but the three main products within Composite Materials and Other Products fell sharply by 23.2% year-on-year.
Key Products
Growth Drivers
- Expected recovery in silicon semiconductor applications driven by the spread of generative AI and increasing data centers
- Steady trend in metallurgical demand such as for industrial furnaces (continuous casting, sintering, etc.)
- Steady demand in the mechanical carbon field, such as bearings and seal rings
- Development of new applications in nuclear and advanced energy fields, such as Graphite Products for High-Temperature Gas Reactors (including order backlog for X Energy, LLC)
- Continued investment in enhancement and development of high-value-added products under the 2030 Management Vision
Risks
- Continued adjustment phase in demand for SiC semiconductor applications (mainly due to sluggish EV demand)
- Weak demand for Special Graphite Products and composite material products due to overall semiconductor market adjustment
- Expanding fixed cost burden from increased depreciation expenses (¥1,200 million in Q1 FY2026 ending December 2026, up from ¥1,030 million in the same period of the prior year)
- Uncertainty in export demand due to the impact of US trade policy
- Risk of rising manufacturing costs due to rising fuel prices amid escalating tensions in the Middle East
