Business network in Tokyo

Hello !
I moved to japan to open a climbing gym, I'm now at the renovation stage and the gym will open in Nakano in march (before the golden week) I'm quite connected in the climbing community but I'm now looking for expending my network, I know that the entrepreneur community is a little bit less important than other country due to the nature of the culture (not a big fan of taking risk) but it might still exist in a smaller size ?

If you having any tips 🙂
