84 VTubers Clash in Song: KADOKAWA ‘CSP’ x JOYSOUND ‘#CSP Utawaku Battle’ Kicks Off Today
KADOKAWA Corporation, in collaboration with XING Inc. (U-NEXT.HD), has launched the large-scale streaming event “#CSP Utawaku Battle Powered by Karaoke JOYSOUND for STREAMER,” running from today, August 12, through August 25 — a two-week competition utilizing the streamer-focused karaoke service “Karaoke JOYSOUND for STREAMER.” A total of 84 VTubers and other creators participating in CSP will compete for the highest scores using the service’s scoring feature.
84 Creators Battle for a Nationwide JOYSOUND Commercial Slot

The event’s main program, “High Score Match,” features a pure scoring competition using Karaoke JOYSOUND for STREAMER’s full-featured scoring system. Participants can attempt and update their records as many times as they like during the event period. The creator who achieves the highest score will receive the “Best Vocalist Award,” earning a 30-second commercial slot aired for two weeks across all JOYSOUND-equipped venues nationwide, along with a special commemorative trophy.
Three Programs Balancing Individual Competition and Collaboration
Alongside the individual High Score Match, two additional programs run simultaneously. The “Cooperative Mission” tallies the total number of songs performed by all participating creators — reaching 1,500 songs unlocks a 7-day Karaoke JOYSOUND for STREAMER license for all participants, while 2,500 songs earns a 14-day license. The “Individual Mission” awards points based on streaming days and personal song counts, with a “Repeating Digits Challenge” offering massive bonus points for achieving palindrome scores. Reaching 80 points earns a feature on official social media and the website, while 150 points unlocks official repost support as promotional benefits.
Interim and Final Results Schedule
The event period runs from August 12 (Wednesday) through August 25 (Tuesday) at 23:59. Interim results showing top-ranking creators will be announced around 6:00 PM on August 21 (Friday) via the CSP official X account, with final results announced around 6:00 PM on August 28 (Friday) on the same account. Viewers can follow along in real time, cheering on their favorite creators’ singing streams while tracking score updates.

“Karaoke JOYSOUND for STREAMER” is a streamer-focused karaoke service designed for singing segments on live streaming platforms like YouTube and Twitch, offering access to over 40,000 songs provided by JOYSOUND.

Commentary and Outlook
This event, co-hosted by major companies KADOKAWA and XING with 84 participating creators, is a landmark project symbolizing the establishment and spread of “utawaku” (singing stream) culture in the VTuber space. Beyond the pure skill-based High Score Match, the inclusion of cooperative elements through the Cooperative Mission and playful mechanics like the Repeating Digits Challenge creates an engaging experience for both participants and viewers over the two-week period. The impact of the grand prize — a commercial aired in JOYSOUND venues nationwide — is significant, and this event has the potential to set a new standard for singing stream events going forward.
