Equivalent location in Tokyo?

I currently live in a commuter town near London and my commute to work is around an hour. I always get a seat on the train to and from work. I live in a 4 bed detached house with garden, worth about £500k.

What’s the equivalent in Tokyo? Even with an hour’s commute, it’s still in the urban area. Ideally I’d always get a seat on the train to the nearest station to my work (Hanzomon). I don’t mind changing as long as the main distance I have a seat. Seeing how busy trains are, I’m guessing I’d have to get on near the start of a line?

There’s Saitama which seems more “rural”, or maybe Hachioji or Kamakura.
