When you hear "far-infrared," you might imagine something like a Kotatsu or a heater—things that "warm you to your core." But what if that far-infrared could actually bring "coolness" in sweltering heat?

There’s a product that unravels the science behind far-infrared mechanisms and applies it for cooling performance. That’s the next-generation functional material "Toko Shoji Co., Ltd." calls "TERAX COOL."

Why was it possible for far-infrared to deliver a function opposite to what we’d expect, by providing cooling? We interviewed Director Mikio Toyama and R&D Department Manager Yumika Sato to learn their secrets and the story behind its development.
