Kume Sen-i began as a small factory in the traditional area of Tokyo. It began domestic T-shirt production before the concept of wearing T-shirts had even reached Japan. These high-quality Japanese-made T-shirts have been a trusted product for more than half a century. Even now, the complete process from material selection to cutting, sewing, inspection, finishing, and design printing is performed domestically under direct management. The T-shirts are tube type, with the material woven in a tube form so that no body stitching is required, making them particularly comfortable.
