Page "Geography of Japan" Paragraph 34

None of the populated plains or mountain basins are extensive in area.

The largest, the Kanto Plain, where Tokyo is situated, covers only 13, 000 square kilometers.

Other important plains are the Nōbi Plain surrounding Nagoya, the Kinki Plain in the Osaka-Kyoto area, the Sendai Plain around the city of Sendai in northeastern Honshū, and the Ishikari Plain on Hokkaidō.

Many of these plains are along the coast, and their areas have been increased by reclamation throughout recorded history.
