Tokyo is such a sprawling metropolis that the outskirts are not particularly urban, and don’t have living costs like that of, say, Shinjuku or Shibuya. It would be like measuring the cost of living in NYC by Dobbs Ferry as opposed to the Upper West Side.
Dobbs Ferry is nice
One year. I loved it there. Watched Wimbleton on hot summer days drinking my Kirin at the bars and watching John McEnroe at the top of his game. “You Idiot!” “My grandmother can see better than that and she’s blind!” The humidity made the beer go down easy with no effect. For a quick meal I took my train pass into the station and stood on the platform eating noodles and then walked out. 50 cents at most. Getting involve with the locals was no fun but small talk was ok. Rabbit hutches? So what? How much do you need for the experience of a lifetime?
