Astro Boy has a brand exclusively sold in Japan, called ASTRO BOY. (Please see the picture, Astro Boy’s trademark.) You can also buy it on Taobao. There is a so-called original T, which is probably About 60-100 per piece. However, there are more miscellaneous brands with Doraemon patterns. Baleno also released a Doraemon sweatshirt this year, which is pretty good.
