Kadokawa announced on October 1, 2026 that its Creator Support Program has entered a partnership with XING's Karaoke JOYSOUND for STREAMER. Creators using CSP, whether individuals or corporate-affiliated, will be able to use the karaoke service's higher-tier plans at a special price. Those plans carry a larger song lineup and support monetization. CSP has worked on projects that used the karaoke service before, including December 2025's Challenge to the World's No. 1 Singing Stream Relay and the 2026 regular program Virtual Utajiman. Karaoke JOYSOUND for STREAMER supports singing covers and singing streams on YouTube, Twitch, Niconico Douga, and TikTok LIVE. It gives access to more than 40,000 songs and starts at 3,500 yen including tax for 30 days. CSP launched in March 2022. Its participating channels number more than 780, with cumulative subscribers above 68 million as of March 2026.
CSP is a secondary-use management and revenue-sharing system that KADOKAWA developed on its own, and it uses the MCN function YouTube provides. The service launched in March 2022 under the group mission "To become a creative platformer that connects the world's talent and inspiration." Its channel base spans VTubers and streamers in Japan and overseas, plus official anime channels and clipping channels. The partnership covers individual creators and corporate-affiliated ones on the same terms.
Karaoke JOYSOUND for STREAMER is operated by XING, part of U-NEXT.HD. The service supports singing covers and singing stream broadcasts, and it includes lyric telop display, a scoring function, background transparency for streaming, and Spout2 support. The two services have worked together before: CSP provided production cooperation for December 2025's Challenge to the World's No. 1 Singing Stream Relay and for the regular program Virtual Utajiman, streamed in 2026. One outlet described the December 2025 event as the "Challenge to the World's Largest Singing Stream Relay."
KADOKAWA says the two sides will strengthen cooperation and run joint projects that use the strengths of both services. Creators and rights holders who want to join CSP can contact the program team by email at csp-info@ml.kadokawa.jp.
