Scarlet Devil Mansion

The Scarlet Devil Mansion (紅魔館 Koumakan), also referred to as the Scarlet Manor or Scarlet Mansion, is a European-style mansion owned by Remilia Scarlet. It is located on a ridge on the edge of Misty Lake. From the outside, there are scarlet-colored windows, but there aren't many windows because of the nature of its vampire residents. There are plenty of rooms without windows at all, too. Through the dialogue of Touhou Hisoutensoku and multiple literary works, it can be said that the entrance to the mansion is usually not fully closed. There is a clock tower on the roof, but the bell on it only rings at night. The inside of the mansion is much larger than is apparent from the outside. This is due to Sakuya Izayoi's ability to manipulate time and space.

Hakugyokurou

Hakugyokurou (白玉楼, "Tower of White Jade") is a ghost shrine overlooking the Netherworld. It is well known among the afterlife realms for its cherry blossom gardens, and many ghosts come to see them every spring. The term Hakugyokurou comes from Chinese legends of the Tang Dynasty (唐朝). It was said to be the place where artists go after death. Li He (李賀), a poet in those days, heard a voice in a dream he had as he was dying; the voice said, "Hakugyokurou has been completely built, so come and write down its details." The story is the beginning of Hakugyokurou. Yuyuko Saigyouji is the lady of Hakugyokurou, and Youmu Konpaku acts as its gardener. The massive youkai cherry tree, the Saigyou Ayakashi, can also be found lying dormant in the gardens of Hakugyokurou.

Hakugyokurou is a place where the ghost resides.

Eientei

Eientei (永遠亭, literally House of Eternity) is the name of a large, old-fashioned Japanese mansion hidden deep within the Bamboo Forest of the Lost. It has hallways that lead out into the far reaches of the sky. Eientei is currently occupied by a large group. Kaguya Houraisan and Eirin Yagokoro have been hiding there since their exile from the Moon. Other occupants include rabbits—lots of them—all under the command of Tewi Inaba and Reisen Udongein Inaba, who protect Kaguya and Eirin from intruders. Every month on the night of the full moon, the residents of Eientei hold a Moon Festival (例月祭, Reigetsusai) offering mochi with medicinal herbs pounded into them. Making mochi is thus the main occupation of the Earth rabbits.

Eientei is deep within the Bamboo Forest of the Lost.
