Daizawa (no meaning)
This will be the easiest Tōkyō place name ever. So, I’ve talked about 北沢 Kitazawa and 代田 Daita. When the civic administration was restructured after WWII, they combined the 2 areas as 代 + 沢. That is all.
Compare the formation of this place name to Ota, which I’ve already written about.
Have an awesome Monday!
