The Hakurei Shrine is a small, run-down Shinto shrine that lies in the mountains of the East, isolated from society. It exists on the boundary between this world and Gensokyo. It is simultaneously accessible from both sides, but some unknown circumstances must be met in order to travel from one side to the other.
The shrine is home to Reimu Hakurei. It's also apparently a popular hangout for all the other girls who Reimu and company defeat in the course of the Touhou games. Behind the shrine is a grove of cherry trees, which is a popular spot for flower viewing in spring.
Very few humans come to this shrine, and even fewer (if anyone at all) leave donations. It has been around for many generations, thirteen at the very least. Because the shrine is old-fashioned, it offers poor protection from the cold. It was thought that the Hakurei Shrine was the only shrine in Gensokyo, but recently the Moriya Shrine has appeared as well. In Reimu's Scenario during the events of Scarlet Weather Rhapsody, it was destroyed by an earthquake caused by Tenshi Hinanawi, and again by Yukari Yakumo, but it was rebuilt with the help of Sakuya Izayoi, Alice Margatroid, and Suika Ibuki.
