Nagakusa-Tenjin-sha, Shinto shrine in Japan

Nagakusa Tenjin Shrine (長草天神社) is a Shinto shrine in Obu, Aichi Prefecture, dedicated to Sugawara no Michizane. It was founded in 1494 when Fujita Tamibu, a landowner of Eibinoso in Chita County, had the Nagakusa land cultivated and installed Michizane, previously enshrined in his residence, as the tutelary deity. The shrine grounds include a brewery where doburoku is made each January.

In 1494, Fujita Tamibu, land steward of Eibinoso in Chita County, ordered the cultivation of Nagakusa and had Sugawara no Michizane, kept in his residence, installed as the tutelary deity on the 19th day of the sixth month. The shrine became a village shrine in 1872 and was listed for offerings of sacred food on 20 October 1907.

The annual festival, held on the Sunday before 25 February, features the Doburoku Festival, designated a tangible folk cultural property by Obu City. Six sake-brewing groups in Nagakusa take turns brewing doburoku from early January in a brewery on the grounds. On the festival day, a costumed Shōjō, an imaginary animal fond of sake, parades through the grounds, and rice cakes are thrown.

The shrine is easy to reach by train or bus and sits close to Kyōwa Station on the Tōkaido Main Line. The grounds are compact and easy to walk around, with short paths and simple layout for visitors of all abilities. The best time to visit is the Doburoku Festival in late February, when the community gathers for celebrations and the area comes alive.

The doburoku brewed for the festival is made from rice grown on a roughly 990-square-metre field that Fujita Tamibu donated in 1494. Brewing stopped in 1665 but resumed in 1668 after an epidemic, at the urging of the local official Ichimura Denbei Katsuyuki. Six sake-brewer groups in Nagakusa take turns brewing at a brewery inside the shrine grounds from early January.
