I'd second this, and add that the range of interests pursued within Tokyo is... unimaginable.
This might be good time for you and your family to learn Hawaiian dance, Alpine yodelling, Dutch lace making, Finnish folk songs, how to be a sommelier, how to tie obi for kimono... you name it, there's a group somewhere in Tokyo doing it.
If you speak a little Spanish, you may find this will give you some common ground if you (or your wife) decide to take up flamenco, Spanish cookery seems to very popular at the moment.
