eientei

The main location of Touhou Imperishable Night. It is the home of Lunarians Yagokoro Eirin and Houraisan Kaguya, Moon Rabbit Reisen Udongein Inaba, and Earth Youkai Rabbit leader Inaba Tewi and her numberless legion of look-alike Inaba Mob rabbits.

It appears to be an old-style pagoda palace in most depictions, and is situated in the heart of the Bamboo Forest of the Lost. Eirin runs her pharmacy service from the building. Fujiwara no Mokou frequently attacks the site in order to draw out Kaguya for another of their unending blood feud brawls.
