Meet a Mug that Reacts to your Ritual.

The Fuji Thermochromic Mug transforms every pour into a quiet moment of magic. Crafted in Japan from HARIO’s signature heat resistant glass, this mug features an elegant illustration of Mount Fuji that changes color with temperature—turning a warm pink when filled with hot drinks (over 50°C) and a cool blue with cold beverages (below 15°C).

More than a mug, it’s a small celebration of Japanese craftsmanship—where design, science, and daily rituals meet.
