Where to play tennis in Tokyo? (and how to find players)

I am an American based in Hong Kong, but will be living in Tokyo this Summer (with my family) and I will also be spending a lot of time in Tokyo over the next 2 years.

I'm looking for advice on where to play, potential hitting partners & lessons for my wife and son.  A little more info about is noted below.

1) I'm 48 and a former college player.  I play competively and am still at a 5.0+ level.  Looking for hitting partners at 4.5 level and above.

2). My wife just started playing a few years ago but plays a lot.  3.0-3.5 level.  Looking for private and or group lessons and hitting partners.  Ideally, she would like to get connect with a group of players for doubles also.

3) My son is 12 and is a low intermediate.  Primary interest is in private or group lessons.

Any suggestions are highly appreciated.

Thanks in advance!
