Saiyaka

Saiyaka [筌莎; さいやか / Sunpaku: すらいじょき] is a city located in southern Uchi Prefecture. As of 2022, it has a population of around 42,000. 
Saiyaka is located on the southern coast of Uchi, and looks out over Nasae Bay, which is the largest and busiest bay area in the Daizō region. As a result, Saiyaka has historically flourished as a centre of fishing and also became a sizeable trading centre in the 16th century. Saiyaka Port is significant as being one of the main ways for ferries, cargo ships and other vessels to enter Uchi Prefecture. From the 1800s onwards, Saiyaka became known primarily as both a merchants' town (aka a popular centre for trade) and a byōbunja.
The Natsumizu River runs through Saiyaka's city centre; it historically provided very good irrigation for rice farming. The Yamadaru National Park takes up about a fifth of the city's designated area to the north.
Saiyaka has a range of reijo (or atsumizu in the local dialect) for bathing as well as other hot springs formed from different minerals for scenic viewing, and is also known for its large deer park. Saiyaka Ō-Atsumizu is one of many well-known resorts in Kanton, with many nearby hotels and yoto, and is the largest "hot spring town" in Uchi Prefecture.
