Ichimokuren

Ichimokuren is a one-eyed kaii linked to wind and rain, venerated as a deity at Tado Mountain in Kuwana, Mie Prefecture. It is enshrined at Ichimokuren Shrine, a subsidiary shrine of Tado Grand Shrine, where it is worshipped alongside Ame-no-Mahistsu-no-Kami, a deity of smithcraft. Ichimokuren embodies both the character of a forge god and that of a tempestuous, dangerous phenomenon—a duality that made it an object of both reverence and caution among fishers and farmers of the Ise Bay coast.

In the most widespread accounts, black clouds rising from Tado Mountain presaged sudden violent winds and storms; coastal people spoke of "Ichimokuren emerging." Fishers maintained the custom of reading omens of Ichimokuren's appearance and returning their boats to shore before danger struck. In farming communities, Ichimokuren was venerated as a deity of wind and rain, the target of prayers for rain and appeals for its cessation. Through its merger with Ame-no-Mahistsu-no-Kami, it was also honoured as a tutelary deity of ironworking and forge craft.

Ichimokuren appears in records from the Tado Grand Shrine's founding history (engi), documented in texts such as the "Tado Jingū-ji Garan Engi Shizai Chō" (early Heian period), through early modern Ise regional geographies, and in scholarly works by Kokugaku (nativist studies) figures including Motoori Norinaga. Modern folkloristics and folklore studies have incorporated it into major reference works and the International Research Center for Japanese Studies' Database of Strange Phenomena and Yokai Lore. It remains an object of study in Shinto, folkloristics, and the history of forge deities.

The layered relationship between Ichimokuren and the one-eyed smith-deity Ame-no-Mahistsu-no-Kami means it is treated both as a deity proper and as a wind-and-rain kaii. In the region, it is addressed with the honorific title "Ichimokuren-sama" and remains an object of ritual veneration at Tado Grand Shrine.
