Yousuke Yukimatsu (行松陽介, Yukimatsu Yōsuke; stylised as ¥ØU$UK€ ¥UK1MAT$U) is a Japanese DJ and producer. Yukimatsu was born in Osaka. Raised on classic rock by his Deep Purple-enthusiast father, he later described the exposure as "a very good education," despite initially feeling indifferent toward the music. During his early youth, he primarily listened to pop music, but in his teenage years, he broadened his musical interests, exploring hard rock and metal in middle school, followed by alternative rock acts such as Sonic Youth and electronic music like The Prodigy in high school. Yukimatsu began DJing in 2008, first performing at a friend's party in his hometown, and soon became a regular presence in local line-ups. Yukimatsu began his career in the underground music scene during the 2010s before gaining recognition in the Japanese club circuit. A turning point came in 2014, when he played alongside techno artist DJ Nobu. Impressed by Yukimatsu's set, DJ Nobu invited him to perform at his Future Terror party in Tokyo, helping establish Yukimatsu’s reputation and contributing to his emergence as a prominent figure in Japan’s club scene. Originally employed in construction, Yukimatsu was diagnosed with a malignant brain tumor in 2016, leading him to leave his job. After undergoing treatment and two surgeries, he shifted his focus entirely to DJing, further developing his experimental style. In early 2025, he gained wider attention for his Boiler Room set in Tokyo, which quickly became one of the platform’s most-viewed videos, reaching over twelve million views on Youtube within half a year. His set featured references to artists such as Romy and Overmono, incorporating elements of acid house. Yukimatsu is known for performing topless during his sets.
