Japanese DJ Tetsuyoshi Kisisita, known by the alias Sisi, has died at the age of 46. The Tokyo-based artist passed after suffering an intracerebral hemorrhage. Rainbow Disco Club, where Sisi played his most recent set, confirmed the news.
Notably, Sisi played at the 17th edition of Rainbow Disco Club earlier this month. The set continued his long association with the festival. He had also been booked for European festivals across the summer, including Love International in Croatia and Sziget in Hungary.
His catalogue stretches back over two decades. Sisi built a quiet but consistent reputation across the global house and disco circuit. His sets carried a deeply curated taste that earned him bookings far beyond Tokyo. Those who heard him often described his selection as patient, precise, and emotionally intelligent.
His 2017 podcast for Resident Advisor remains one of the strongest entry points to his sound. The 2019 Rainbow Disco Club edition then placed his set among the festival’s standout performances of that year. The wider electronic music community is now reflecting on his contribution.
The team at Rainbow Disco Club shared the news on social channels with a quiet tribute. Fans and colleagues across the Japanese and international scenes have begun posting their own memories. Listen back to Sisi‘s 2017 RA podcast to revisit his sound. Our thoughts are with his family, friends, and collaborators.
