Saijō (西城町, Saijō-chō) was a town located in Hiba District, Hiroshima Prefecture, Japan.

It then went through several mergers with other towns and villages in the area before being incorporated itself into the city of Shōbara in March 2005.

After 106 years of independent history, the town of Saijō ceased to exist, and it became a municipal division within Shōbara.

Japan National Route 314 travels south from Shimane Prefecture, then turns east toward Okayama Prefecture after briefly joining Japan National Route 183 for about 1 km at Bingo-Ochiai Station.

Japan National Route 183 originates in Naka-ku, Hiroshima and terminates in Yonago, Tottori.

Route 183 instead continues northeast past the turnoff for Dōgoyama Takahara Ski Resort before entering Tottori Prefecture.

Bingo-Ochiai Station, located 5.6 kilometres (3.5 mi) north of Hibayama, connects with the Kisuki Line and is just a few hundred meters south of the Akagi Internal Medicine Clinic.
