Business Details
The Japan segment of Toomen Device is a business in which the Company itself purchases products from the Samsung Group and sells them to domestic customers within Japan. Product categories handled include memory (DRAM, NAND FLASH, SSD, etc.), system LSI (CIS, SiP, foundry, etc.), display (LCD, OLED), and others (LED, MLCC, batteries, etc.). Automotive and SiP businesses are the primary sources of revenue, and the Company operates sales offices located close to domestic customers to conduct detailed sales activities.
Recent Overview
Net sales up 25.6% and profit up 61.4% driven by expansion in automotive and SiP businesses
In the Japan segment for FY2026 (ending March 2026), driven mainly by increased sales in the automotive and SiP (System in Package) businesses, net sales reached ¥159,885 million (up 25.6% year on year) and segment profit reached ¥7,094 million (up 61.4% year on year), achieving substantial growth in both revenue and profit. Segment assets expanded to ¥116,976 million, approximately 2.2 times the prior period level, due to an increase in inventories and other assets.
Key Products
Growth Drivers
- Expanding demand for data center memory semiconductors (DRAM, NAND FLASH for servers and storage) driven by the spread of generative AI
- Increased demand for memory semiconductors and OLED driven by progress in ADAS, autonomous driving, electrification, and integrated cockpits in the automotive market
- Growth in the system LSI field driven by expansion of domestic SiP business sales
- Improved profitability driven by rising memory semiconductor prices
- Stable procurement capability based on a strong purchasing and sales relationship with the Samsung Group
Risks
- Risk of escalating trade friction due to changes in U.S. trade policy (impact on demand and procurement from tariff increases, etc.)
- Risk of fluctuations in memory semiconductor market conditions (deterioration of profitability during price downturns)
- Risk of sluggish automotive-related demand due to slowing growth in the EV market
- Risk of foreign exchange rate fluctuations (impact on sales and profit from yen appreciation)
- Risk of fluctuations in domestic system LSI demand, including SiP and foundry businesses
- Risk of dependence on the Samsung Group as the primary supplier (procurement concentration risk)
