Where is the city built near the Tanukis home?
The Tanukis lived among the Tama Kyuryou, (Tama Hills), in West Tokyo. The Japanese government (in reality and in the movie) built a totally new town with high-rise apartments, schools, hospitals, and so forth. The town is called “Tama New Town”. It is no longer new today, since about a quarter of a century has passed since it was built.
