Business Details
The domestic segment handled by Toyota Boshoku Corporation itself. Develops, produces, and sells automotive interior parts (Door Trim, Headliners, Filter Products, etc.) including seats, with Toyota Motor Corporation and Toyota Auto Body Co., Ltd. as its main customers. In FY2026 (ending March 2026), revenue to external customers was ¥891,184 million, and the amount including intersegment internal sales was ¥968,029 million. This is the largest segment, accounting for approximately 47% of consolidated revenue, and has built an integrated development and production system centered on domestic production sites.
Recent Overview
Revenue increased due to new product launches, but operating profit declined approximately 50% year-on-year due to quality-related expenses.
In FY2026 (ending March 2026), the Japan segment's revenue increased ¥28.7 billion (3.1%) year-on-year to ¥968,029 million (¥891,184 million to external customers), driven by new product launches, among other factors. On the other hand, operating profit came to only ¥5,110 million, a decrease of ¥5.0 billion (49.8%) year-on-year, despite the disappearance of the impact of impairment losses recorded in the prior period and the effects of new products and rationalization associated with model changes, as the recording of quality-related expenses weighed on results. The operating profit margin declined from 1.08% in the prior period to 0.53%.
Key Products
Growth Drivers
- Expansion of revenue through the effect of new product launches (interior parts such as seats) associated with model changes
- Strengthened competitiveness through an integrated development and production system from seat frame to finished seat
- Improvement in variable costs and rationalization effects through cost planning and VA promotion
- Strengthening of cabin space planning and proposal capabilities as an Interior Space Creator
- Improved manufacturing competitiveness through production process improvements utilizing TPS and DX
- Creation of new revenue sources through development and commercialization of environmentally friendly advanced materials such as CNF
Risks
- Impact on performance from fluctuations in automakers' production volume, sales volume, and vehicle model mix (dependence on the main customer, the Toyota Motor Group)
- Risk of significant downward pressure on profit margin due to recording of quality-related expenses (materialized in FY2026 ending March 2026)
- Cost pressure from persistently high raw material and logistics costs
- Risk of profit margin decline due to increased miscellaneous expenses (personnel costs, etc.)
- Risk of recording impairment losses (recorded in FY2025 ending March 2025)
- Risk of product portfolio transition due to slowing BEV market growth and technological innovation such as SDV adoption
