Kasama Inari Shrine, Shinto shrine in Ibaraki, Japan

Kasama Inari Shrine is a Shinto place of worship in Kasama city, Ibaraki Prefecture. The forested hillside grounds contain prayer halls with curved roofs, stone lanterns, and rows of red gates leading to elevated shrines.

Tradition holds that the shrine was founded in 651, during the Hakuchi era, beneath a walnut tree; no written record survives. The present main hall, a combined outer and inner sanctuary, was built in 1860 by the eighth Makino lord, Naonao, and was designated an Important Cultural Property in 1988. The lords of Kasama, including the Inoue and Makino families, made it their prayer shrine.

The shrine is counted among Japan's three major Inari shrines, and its deity Ukanomitama-no-mikoto is honoured for grain harvests and thriving business. Its festival, the Reisai, falls on 9 April, held to be the founding day. From mid-October to late November the grounds host the Kasama Chrysanthemum Festival, begun as a morning-glory show in 1890 and extended to chrysanthemums in 1908; horse archery and sword demonstrations accompany it.

The entrance lies a short walk from the train station and can be reached on foot. The paths through the grounds climb uphill along winding steps.

The shrine keeps a pendant inscribed "Kasama Inari" that was found on singer Kyu Sakamoto after the 1985 Japan Airlines crash; he had survived a 1943 train accident as a child and credited the shrine, holding his wedding here. The main torii, rebuilt in 2016 from steel at about 10 m, is painted "Kasama vermilion", a colour named after 2013 for the approach street.
