Julius is a Japanese fashion label run and designed by Tatsuro Horikawa. The label focuses on presenting a wide array of gothic inspired clothing, utilizing the color black extensively to explore its meaning in both Avant Garde, spiritual, and religious aspects of the designer’s life. Started as a primarily art related project, Julius has surpassed Horikawa's original label focus in Nuke, presenting in the Tokyo Collection annually since 2004 and growing to a cult status in both Japan and abroad.

Designer Tatsuro Horikawa started his own design company in 1996 with Third Stone Co. Ltd, followed the following year by his first fashion label, Nuke. The label was a large success but lasted only until his next major project was undertaken in Julius, started in 2001 as an art project to present audio and video presentations for Spring/Summer collections and art shows. The label grew from there becoming a fully fledged fashion project that coincides with artistic endeavors from Horikawa.
The first presentation of clothing and audio/video projects from Julius occurred in 2004 with the Spring/Summer collection at the Tokyo Collection. A follow up show occurred at the Modern Art Gallery as well with paintings and abstract art pieces that inspired his clothing line.
