Yes! Of course, you can join it. Half of our members started the martial arts as beginners.
For Shinjuku gym, the female percentage is about10%, and for Komazasa gym, it is about 30%.
Female students tend to participate in the fitness classes or beginners’ kickboxing classes.
All trainers are kind and they strive to give lessons to convey the fun of the martial arts.
It depends on your level as an experiencer, but we think that you could participate in a match for amateurs in about 1 year.
For your becoming a professional, you have to achieve goods results in amateur tournaments.
In the kickboxing class, only light sparring is available, but you can immediately start sparring after you work out several times. As for jujutsu or grappling, you will start it with more skilled athletes little by little after you work out several times.
Of course not. No problem. Almost all members come to the gym to do exercises with enjoyment.
We do not warrant that no accidents would occur due to the nature of the martial arts, but the accidents which lead to heavy injuries rarely occur. Our instructors carefully supervise the whole class to prevent any accidents.
The Shinjuku gym and Komazawa gym have 1 shower respectively.
Currently, we have no events due to the new corona virus pandemic, but all members used to go to see the matches to cheer for the participants. If the pandemic is over, we plan to hold drinking parties again as we used to do so.
