Not sure if anyone else saw this or is interested but someone uploaded Junya Watanabe's final/retirement skate at Kansai Free.
It includes the footage of Kazuki and other skaters (Mitsuki, Taichi Honda etc...) hugging/thanking him after his performance.

Kazuki appears at 7:03 but it's pretty cool to see how how everyone cheers for/"high touches" Junya before his skate.
I always find it incredibly touching to see just how much the Japanese skaters seem to respect and support each other.
I'm really happy these friendships are important to Kazuki and he continues to participate in small local and intercollegiate competitions.
