The Hanten jacket is a traditional Japanese clothing garment that originated in the Edo period (1603-1867). It’s a form of casual or informal everyday wear suitable for both men and women. It is a rectangular jacket, worn either on top of other clothing or as a form of nightwear. This traditional Japanese clothing was worn by those who worked outside in the cold and was meant to be a warm outer garment. Its warmth, comfort, and utilitarian features make it an ideal garment for cool days. The garment can be worn open like a jacket or coat or fully closed with closure ties at the front. It usually comes with two large inside pockets big enough to hold your wallet, keys, and mobile device.
