## Launch of 'COOLCORE®' Setup and Short-Sleeve Business Polo Shirt
Haruyama Trading Co., Ltd. (Headquarters: Okayama City, Okayama Prefecture; President: Masafumi Haruyama), a company that supports the health of business professionals, will launch 'COOLCORE®' setups and short-sleeve business polo shirts using patented cooling materials under its original brand 'TOKYO RUN' at all Haruyama stores nationwide starting Saturday, May 23, 2026.
As the Ministry of the Environment warns of 'life-threatening heat,' Japanese summers are becoming increasingly severe each year, making heatstroke prevention outdoors a major issue. Amidst this situation, demand is growing for business attire that compromises neither on functionality nor on aesthetic quality, and this product meets those expectations.
### Realizing 'Cool, Dry, Comfortable, and Long-lasting' through Fiber Power
The core of this product lies in the patented cooling fabric technology uniquely developed by COOLCORE®. It exhibits a natural cooling effect by quickly absorbing, dispersing, and evaporating moisture, effectively lowering the wearer's perceived temperature and overturning the conventional standards of business attire.
Furthermore, because the cooling effect is generated by the fiber structure itself rather than through chemical processing, the functionality is not compromised by repeated washing, ensuring comfort that lasts semi-permanently. While maintaining the professional 'formal' look required in business settings, the setup features a detailed dot-patterned fabric design that offers high breathability, keeping the wearer cool and dry even during long hours of wear. The short-sleeve business polo shirt offers a stylish design and a soft fabric feel, suitable for dressed-down professional ensembles.
