Exhibiting at the '12th Heatstroke Prevention Expo'! Debut of 'OptiBlock,' a new high-standard heat-shielding material brand developed entirely in China, plus the 'Evaporative Cooling Vest × Fan-Integrated Wear'!

Tamura Koma Co., Ltd. (Head Office: Osaka City, Osaka Prefecture; Tokyo Office: Shibuya-ku, Tokyo; Representative: Kiyohito Hori) will exhibit at the '12th Heatstroke Prevention Expo,' held from Wednesday, July 15 to Friday, July 17, 2026, at Tokyo Big Sight East Halls 7 and 8.

Highlight: The debut of 'OptiBlock,' a new heat-shielding-focused material brand!

At this exhibition, we will officially unveil our new functional material brand 'OptiBlock (OptiBlock),' specifically engineered for superior heat shielding.

Developed and produced entirely in China—one of our global hubs—from yarn spinning to knitting, weaving, and dyeing.

Materials meeting the high standards of S45+ heat block and UPF50+ UV protection will be marketed under the 'OptiBlock' brand.

Arm covers made with OptiBlock will be on display.

By blending with nylon and other fibers, we offer materials that not only block heat but also provide cool touch sensation and high breathability—ideal for combating extreme heat.

Sample of the 'Evaporative Cooling Vest × Fan-Integrated Wear' using 'OptiBlock' will be exhibited.

We will also propose the 'Evaporative Cooling Vest × Fan-Integrated Wear' utilizing 'OptiBlock' technology.

We invite you to visit our booth to experience these innovations firsthand.
