Koikuchi Work Shirt
Koikuchi Work Shirt
The koikuchi shirt, traditionally worn under hanten during mikoshi carrying, dates back to the Edo period. Originally favored by stylish craftsmen, its sleeve openings were angled for ease of movement, resembling a carp's mouth—hence the name koikuchi. Over time, it became cherished as both a practical undershirt and festive attire.
