Trusco Nakayama’s Human Cooler Hits 200 Units Sold Amid Japan Heat Crisis

Trusco Nakayama (9830.T) is capitalizing on Japan’s extreme heat crisis with its “Do-Reemon BOX,” a human-sized cooling unit priced at 1.5 million yen. Since launching in April, the company has sold approximately 200 units to factories, construction sites, and golf courses. With temperatures exceeding 40 degrees Celsius now classified as “severe heat days,” demand is accelerating and international orders are arriving from Germany and the United States.

How the cooling box works

The Do-Reemon BOX is a glass-door cabinet where a person sits while 5-degree Celsius air flows across the neck, shoulders, and back. The interior maintains 15 degrees Celsius. Users can lower their body temperature in roughly 10 minutes. The unit has wheels for easy movement and requires only a standard electrical outlet, making it deployable in outdoor spaces and open areas where air conditioning is impractical.

Demand driven by record heat and new safety rules

Japan recorded its first “severe heat day” (40+ degrees Celsius) in 2026, with multiple occurrences already in Fukuoka, Kumamoto, and Kagawa prefectures. In 2025, Japan’s Ministry of Labor mandated that employers implement heat illness prevention measures. Trusco’s corporate spot-cooler sales have doubled yearly for several years. The company loaned units to evacuation shelters after the Kumamoto earthquake, signaling versatility beyond commercial use.

Expansion into retail and overseas markets

Trusco plans to deploy units in shopping malls and summer outdoor festivals, with time-based rental pricing similar to massage chairs under consideration. Germany and the United States have already inquired about purchasing, prompting the company to pursue regulatory certifications in each country. Trusco product manager Fumitake Matsubara stated the unit targets heat-illness prevention, not merely comfort breaks.

Stock momentum amid product success

Trusco Nakayama stock rose 3.07 percent to 2,450 yen on August 6. Meyka rates the stock B+ with a neutral recommendation, citing a PE ratio of 9.96 and a 12-month price forecast of 2,332.81 yen. The company’s industrial distribution business benefits from rising corporate spending on worker safety and heat mitigation, though the stock trades below its 50-day moving average of 2,279.26 yen.

Final Thoughts

Trusco’s Do-Reemon BOX addresses a real market need as Japan’s heat intensifies and workplace safety rules tighten. With 200 units sold in four months and overseas interest growing, the product diversifies revenue beyond traditional industrial distribution. At a B+ rating and 9.96 PE, the stock offers value for investors betting on sustained heat-driven demand.
