8M JPY/year in Tokyo – what does life look like?

I am about to accept an offer for 8M JPY with Rakuten (yes, I know).

What does life at 8M JPY (total comp) look like in Tokyo? I have tried running the numbers thru the Japan tax calculator but I guess it doesn’t take into account part of that being bonuses? For people here at that salary level, how much are you spending on rent? When factoring in phone/internet and utility costs, how do you come out at the end of the month?

I’d be looking at Meguro, Setagaya or Nakano, a 1 bedroom and hopefully a parking spot. I’m also open for any other suggestions area-wise that provide a good trade-off between central Tokyo and Setagaya!

Thank you!
