Freestyle trampoline at professional level in Tokyo 

Hello everyone, I am reaching out to the community for some crucial information and would greatly appreciate any professional or insider knowledge you might have.

My son, who currently trains at a professional high level in freestyle trampoline, is considering a move from Norway to Tokyo. However, his continued dedication to his sport is a non-negotiable condition for this major life transition.

I am struggling to find reliable, high-level training options online and need help locating suitable facilities or groups.

My key questions are:

1. Gyms/Clubs with Olympic Trampolines: Are there any dedicated trampoline or gymnastics gyms/clubs in or near Tokyo that have access to Olympic-standard trampolines (not just recreational parks)? We are looking for equipment that supports advanced training.
2. Acrobatic/Freestyle Training Groups: Are you aware of any acrobatic groups, trampolining teams, or freestyle communities that train together regularly in the Tokyo area? He is at a high-level and needs an environment that fosters progression, coaching, and peer training.
3. Language Barrier / International Training: Are any of these facilities or groups known to be welcoming to non-Japanese speaking high-level international athletes, perhaps with some English-speaking staff or coaches? (Though we are prepared to manage with Japanese where necessary).

Any specific names of clubs, coaches, or facilities would be incredibly helpful. Securing his training future is the deciding factor in our move.

Thank you so much for your time and assistance!
