Gensokyo

Gensokyo is a fictional, isolated land that serves as the primary setting for the Touhou Project series of Japanese doujin games, developed by ZUN. It is a place where youkai, spirits, gods, and humans coexist, though the human population is relatively small and lives in villages, often protected by powerful beings. The boundary between Gensokyo and the outside world is sealed by the Great Hakurei Barrier, maintained by the Hakurei Shrine Miko, Reimu Hakurei. This barrier prevents most humans from entering or leaving Gensokyo without permission and also keeps the youkai within its borders.

The geography of Gensokyo is varied, encompassing forests, mountains, lakes, and human villages. Notable locations include the Hakurei Shrine, the Scarlet Devil Mansion, the Moriya Shrine, and the Misty Lake. Time and space within Gensokyo are not always consistent with the outside world, and various legends and myths from Japanese folklore and other cultures are said to manifest there. The inhabitants of Gensokyo are diverse, ranging from powerful individuals like the witch Marisa Kirisame and the vampire Remilia Scarlet to lesser-known spirits and creatures. The typical narrative structure of the Touhou games involves a "main character" encountering and defeating various spellcard-wielding individuals to resolve an incident that threatens the peace of Gensokyo.
