横浜, pronounced Yokohama, is a big city near 東京 (Tokyo). It has many nice spots such as 桜木町 (Sakuragicho) and 中華街 (pronounced Chukagai, meaning Chinatown).
There are frequent trains from 東京駅 (Tokyo station).
Travel tips: Have lunch in Chinatown. From there take a look at 山下公園 (Yamashita park) and walk to 桜木町 (Sakuragicho).
