Cold vs Hot Labels (つめたいとあたたかい - Tsumetai / Atatame)
Japanese vending machines feature blue labels for 'Tsumetai' (Cold) and red labels for 'Atatame / Atatakai' (Warm/Hot), allowing you to buy hot and ice-cold drinks side-by-side.
Introduced in the 1970s, eco-friendly heat-pump technology was developed in Japan. It utilizes heat discarded during beverage cooling to warm the hot drinks simultaneously.
Simply check the color under the drink display before pressing. Press buttons below blue strips for ice-cold sodas/teas, and red strips for steaming hot cans.
