I was looking into whether the K-On! VAs still keep in touch, and I came across a recent interview with Yoko Hikasa from February 2026.
She was asked if the five of them still get together, and apparently they don't really meet as all five anymore. But she said she still goes out to eat with Satomi Sato and Ayana Taketatsu, and sometimes meets up with Aki Toyosaki and Minako Kotobuki as well.
She also mentioned that the last time all five of them were together was at Animelo Summer Live 2019, when they reunited as Ho-kago Tea Time.
I don't know why, but I find this really wholesome. It's been so many years since K-On!.. idk it is kinda silly
It's nice to know that the five of them didn't just completely lose contact after K-On! ended. It gives me hope that their characters did the same. (probably more than them haha)
