長崎街道嬉野湯宿 東構口跡 Sites of Higashi Kamaeguchi(town gate)
During the Edo period, the plain of Ureshino was governed by Hasuike Sub-domain, while its mountains were owned by Saga Domain. The post town of Ureshino on the Nagasaki Kaido belonged to Hasuike Sub-domain. Also known as "Ureshino Yuyado" or Ureshino Hot Spring Town at that time, this post town had a town gate on both the east end and the west end of the street, which marked the borders of the town and were called "Kamaeguchi."
The eastern gate was built near the present entrance of Wataya Besso, facing the main street, and the western gate was built near the entrance of Taishoya. The post town was about 500 meters long, and the gates did not have doors or guardians at ordinary times. However, in case of emergency, these gates served as important points of defense.
The post town consisted of approximately 100 houses with thatched roofs along the street, including over 30 accommodations, cheap lodgings, and merchant houses. At the center of the post town was Toyotamahime Shrine, adjacent to Ochaya (Joshiya), the station where porters and horses were changed and where the bulletin board to display notices from the government was located. Along the Ureshino River, there was a hot spring bath operated by the Domain. In addition, about 300 meters north of the main street, Zuikoji Temple was used as the lodging for government officials, including Nagasaki Bugyo (governor).
