UnDeR20 Story

UnDeR20 was founded on January 23, 2021 by the artist, TenGuSan. Since its establishment, we have been dedicated to the design and release of original toys, which have been widely recognized across Asia, in particular, Japan and China. In 2023, we started our own clothing and accessories lines because we felt that we couldn't find clothes that truly excited us anymore. So we are going to create them ourselves.

From toys to streetwear, just like our name suggests, we have always been "under 20 years old." We uphold our slogan, "Wandering Soul, Untamed Heart." We gather artists from around the world and always stand with the "wildest" young people. A revolution without dancing is a revolution not worth having, right?
