also: なかがみ
noun
Ten'ichijin; Nakagami; directional taboo deity
In Onmyōdō, a god of fortune whose location changes daily in a clockwise circuit; traveling in that direction is considered unlucky. The detailed cycle is given in the English gloss.
陰陽道では、天一神のいる方角へ旅立つのは避けるべきとされた。
In Onmyōdō, it was said that one should avoid setting out in the direction where Ten'ichijin resides.
天一神は、己酉の日から癸巳の日まで地上を巡ると伝えられる。
Ten'ichijin is said to travel the earth from the day of Tsuchinoto-Tori to the day of Mizunoto-Mi.
The name 天一神 (Ten'ichijin) literally means 'Heaven-One Deity'. The reading なかがみ for 中神 is a native Japanese reading meaning 'middle god', referring to the deity's position in the directional cycle. The exact historical origin is uncertain, but the deity is firmly rooted in Onmyōdō traditions.
