Business
TOMOKU Co., Ltd. was founded in 1940 and is listed on the Prime Market of the Tokyo Stock Exchange as a comprehensive corporate group. The company, together with 34 consolidated subsidiaries and 6 affiliated companies, operates three business segments: manufacturing and sales of Corrugated Sheets & Corrugated Cases and Printed Paper Containers (domestic and overseas), design, construction, and sales of high-performance imported homes under the Sweden House brand, and the Freight Transportation Business and Transportation & Warehousing business. Major customers include processed food and beverage manufacturers (Ito En, Ltd. is the largest customer, accounting for 10.9% of net sales), purchasers of custom-built homes, and major retailers. The company also has corrugated cardboard manufacturing facilities in the US and Vietnam, conducting business both domestically and overseas.
Business Model
In the Corrugated Cardboard business, the company has built an integrated system spanning raw material procurement through manufacturing and sales, limiting inventory risk through made-to-order production. In the Housing business, it provides one-stop design, construction, supervision, and sales services using components imported from Sweden, and has also established a system covering renovation. In the Transportation & Warehousing business, it secures stable handling volumes by operating dedicated logistics centers for specific customers such as beverage and food manufacturers. The mutual complementarity among these three businesses enhances earnings stability.
Company Strengths
The company received 6 awards at the World Packaging Organisation's "WorldStar Awards 2026," the most among domestic companies. It continues research and development of packaging designs that are resource-saving, energy-saving, and easy to open and recycle, as well as unique shapes, giving it differentiated competitiveness through high-quality, high-value-added products. R&D expenses for the Corrugated Cardboard Business alone amounted to ¥188 million.
Sweden House Co., Ltd. ranked first overall for 12 consecutive years in the Oricon Customer Satisfaction Survey for Custom-Built Homes by Housing Manufacturers. Its unique concept of highly airtight, highly insulated energy-saving homes, combined with a long track record of customer satisfaction, makes imitation by competitors difficult, giving it a structure that allows brand premium to be reflected in pricing.
Since 2021, the company has successively made subsidiaries of Tamayoshi Co., Ltd., Hoju Unyu, Nichiei Shiko, Enshu Shikogyo, Yamato Corrugated Cardboard, Kuniyoshi Co., Ltd., Fujisho Co., Ltd., and others. It has also continued capital investment, including the startup of Taiyo Co., Ltd.'s new Isehara plant (January 2026) and the introduction of state-of-the-art high-speed printing machines at the Kyushu plant, with capital investment for FY2026 (ending March 2026) reaching ¥10,872 million.
ENVALITH's Perspective
Performance Trend
Revenue maintained a broadly expanding trend, moving from ¥206,007 million in FY2022, to ¥212,817 million in FY2023, ¥211,526 million in FY2024, ¥219,613 million in FY2025, and ¥224,090 million in FY2026 (ending March 2026). Operating profit temporarily declined to ¥7,452 million in FY2023, but then recovered sharply on the progress of price pass-through, rising to ¥8,057 million in FY2024, ¥9,360 million in FY2025, and ¥11,378 million in FY2026 (ending March 2026), setting a new high over the past five fiscal years. Profit attributable to owners of parent also reached a record level of ¥7,361 million (up 13.1% year on year). While trends in Corrugated Cardboard raw material and energy costs remain an external factor affecting earnings volatility, the gross profit margin improved (from 16.8% in the previous period to 18.1% in the current period) as product price revisions took hold. For FY2027 (ending March 2027), revenue is projected at ¥220,500 million (down 1.6% year on year) due to the impact of the sale of Itoen Logitem, but operating profit is expected to continue increasing to ¥12,700 million (up 11.6% year on year).
Growth Strategy
Under the launch of the Third Medium-Term Management Plan, the company aims to enhance corporate value through higher value-added Corrugated Cardboard, comprehensive Housing proposals, and logistics optimization
The company continues sales activities focused on profit margins while strengthening its integrated development, manufacturing, and sales system for high-quality, high-value-added products, exemplified by WorldStar Award-winning products. It has set a policy of further focusing on overseas businesses (Vietnam and the US) expected to drive growth. Production capacity has already been enhanced through the introduction of a state-of-the-art high-speed printing press at the Kyushu Plant and the launch of Taiyo Corp.'s new Isehara plant.
Following the absorption-type merger with Sweden House Reform Co., Ltd. (completed July 2025), the company will integrate the Home Design business of Hokuyo Trading Co., Ltd. in April 2026. NORDIC DESIGN CENTER (NDC) has been opened in Tokyo Ariake, establishing a system capable of comprehensive proposals covering new construction, interior design, and renovation. The company aims to enhance brand value and customer satisfaction, and to strengthen its earnings base amid a challenging market environment.
The business portfolio has been optimized through the sale of Ito En Logitem Co., Ltd. (April 2026). Fujisho Co., Ltd. (Okayama) is being utilized as a key hub for relay transportation to address the 2024 logistics problem. The company is diversifying its revenue sources by deepening its presence in the beverage sector, expanding new handled items such as agricultural machinery parts and machine parts, and increasing its own vehicle fleet and establishing new warehouse locations.
For FY2026 (ending March 2026), the annual dividend was significantly increased to ¥130 per share (up from ¥100 in the previous fiscal year), with a payout ratio of 29.1%. For FY2027 (ending March 2027), an annual dividend of ¥170 (interim ¥85, year-end ¥85) is planned, with the payout ratio expected to rise to 34.6%. While maintaining stable dividends as a basic policy, the company will balance the enhancement of retained earnings with shareholder returns.
