The largest post station on the Tokaido Road, and seat of the Tokugawa Clan
Fuchu-shuku was the largest post station on the Tokaido Road, and it flourished as the castle town of Sumpu Castle. In 1609 during the reign of Tokugawa Ieyasu, he laid out a castle town known as the layout of Sumpu. Similar functions and occupations were gathered in blocks of the town which was laid out in a grid pattern, with each block playing its own role. This castle town layout later came to be called Sumpu Kyujurokka-machi, and about thirty district names from that time are still in use today. The beautifully laid out streetscape in a grid pattern also forms the foundation for modern urban development.
