Alliteration is fun, although it makes my post title somewhat misleading.
Tokyo itself is a large city, split into 23 smaller wards, each of their own a city of its own. They each average about 375,000 residents, but especially commercial and office-intensive areas see those numbers swell as millions of suburbanites head into town for the daily grind. Those people come mainly from Chiba, Saitama, and Kanagawa Prefectures. Saitama lies to the north, with over 7 million residents. about a quarter of a million of them live in the 10-square-mile city called Soka.
Soka has a nice university and a public library with English-language books. There's a Chinese restaurant on the west side of Soka Station (though I couldn't tell you exactly where) that I have to find again, because it's pretty tasty! And I'm sure there's more to offer as well. But really, once you get outside of Tokyo, bedroom communities rule the roost and there really isn't much for tourists to see.
