I kept it at home. I believe it's a bamboo hat (takegasa) or a miyagasa, woven from bamboo and used for sun and rain protection. It's tightly woven and in beautiful condition, with no tears or fraying. It's highly breathable and provides shade for the entire head, making it comfortable to wear even in hot conditions. To wear it on your head, you usually need to attach a "gotoku" (a support structure) inside, but it's already attached, so you can use it immediately by attaching a chin strap (see photo 3). Perfect for walking the "Kuma Ancient Trail" ♪ It's used for leisure and practical purposes such as festivals, fishing, and farming. Hat Diameter: Approximately 34.5cm Gotoku Diameter: Approximately 18cm
