square paper lantern
A traditional Japanese standing lantern with a square frame covered in paper, often used indoors or in historical settings.

行灯 is a general term for a paper-covered standing lantern, while 角行灯 specifically refers to one with a square shape.
Compound of 角 (kaku, 'square') and 行灯 (andon, 'paper lantern'). The exact historical origin is uncertain, but the word straightforwardly describes a square-shaped andon.
