Dear Whistlers,

Starting with WWC2026, the Recorded Accompaniment Category will be discontinued, and A cappella Category will be established.

– The A cappella Category is for solo whistling performances without accompaniment.
– The A cappella Category will maintain the same age divisions (Child, Teen, Adult, Senior) as the previous Recorded Accompaniment Category.
– In the A cappella Category, participants will perform Classical and Popular pieces, as in the previous Recorded Accompaniment Category.
– For the A cappella Category only, the minimum performance time (per piece) will be changed from 2 minutes to 1 minute 30 seconds. The maximum performance time will remain the same as the previous Recorded Accompaniment Category.
– With this change, solo performances without any elements other than whistling will no longer be permitted in the Allied Arts category. (Other recorded accompanied performances are still allowed.)

Further details will be posted on the official website in the guidelines.

Thank you for your understanding.

Dear Whistlers,

Thank you for your patience.

WWC2026 is scheduled to be held for four days, from Thursday, June 18th to Sunday, June 21st, 2026.
(Depending on the number of entries, it may be held for three days, from Friday to Sunday. This will be decided after the deadline for Recorded audition.)

The venue will be the same as WWC2024, “Kawasaki City Gender Equality Center (Scrum21 Hall)”.
The Recorded audition period will be a little longer this time, from mid-October to mid-December 2025.

We look forward to receiving many entries.
Please stay tuned!
