【 チロルチョコ (chiroruchoko) 】”Tirol Choco” by Tirol Choco
Inspired by the nature and simplicity of the Tyrol region of Austria, the original チロルチョコ was in the shape of three current-size cubes connected, like three mountains. When it was introduced in 1962, as chocolate was still a luxury, the 10-yen chocolate quickly became popular.
