San'indō (山陰道; Japanese pronunciation: [saɰ̃.iꜜn.doː]) is a Japanese geographical term. It means both an ancient division of the country and the main road running through it. San'in translates to "the shaded side of a mountain", while dō, depending on the context, can mean either a road, or a circuit, in the sense of delineating a region. This name derives from the idea that the northern side of the central mountain chain running through Honshū was the "shaded" side, while the southern side was the "sunny" (山陽 San'yō) side. The pre-modern region corresponds for the most part with the modern conception of the San'in region.

The region was established as one of the Gokishichidō (Five provinces and seven roads) during the Asuka period (538–710), and consisted of the following eight ancient provinces: Tanba, Tango, Tajima, Inaba, Hōki, Izumo, Iwami and Oki. However, this system gradually disappeared in the centuries leading up to the Muromachi period (1333–1467).

Izumo Daijingū (出雲大神宮) is a Shinto shrine in the Chitose neighborhood of the city of Kameoka in Kyoto Prefecture, Japan. It is the ichinomiya of former Tanba Province. The main festival of the shrine is held annually on the October 21.

Toyouke-hime (豊宇気毘売, Toyouke-bime; lit. "Luxuriant Food Princess") is the deity (kami) of food and grain in the Shinto religion. Originally enshrined in the Tanba region of Japan, it is said she was called to reside at Gekū, Ise Shrine in the 5th century during the reign of Emperor Yūryaku to offer sacred food to Amaterasu Ōmikami, the Sun Goddess.

While popular as Toyouke-Ōhmikami presently, her name has been transcribed using Chinese characters in several manners including Toyouke bime no kami (豊宇気毘売神) in the Kojiki, while there is no entry about her in the Nihon Shoki.
