When it comes to summer essentials, a classic straw hat is a must, and few do it better than Tanaka Hat Shop, a historic brand from Kasukabe City in Saitama Prefecture. Founded in 1880, this long-established workshop continues to preserve and pass down Japan’s traditional straw hat-making techniques.

Crafted from natural straw, their hats are lightweight, breathable, and gently fragrant with the scent of fresh wheat.
