Chokyūkai's palace

 was where Chokyūkai lived after the shrine he was sealed in was destroyed. It was also where he kept his harem of human wives. It was a very large palace with a central room that was dedicated for Chokyūkai and his wives. Chokyūkai would sit in the center while his wives were lined up along the sides of the room. The outside of the palace had a large pillar behind the main building.

History
Chokyūkai stayed there after a horde of yōkai destroyed the shrine he was imprisoned in following the collapse of Mount Hakurei. He abducted human women to be his brides using his enchanted tiaras and brought them to his palace. After he kidnapped Kagome, Inuyasha's group went to his castle to rescue her. They send Shippō transformed as a young woman to distract Chokyūkai. He could not maintain his transformation and transformed back, but he distracted to distract Chokyūkai long enough for Inuyasha to rescue Kagome and give her his bow and arrow. He also gave her Miroku's special Chinese sutra to use against Chokyūkai with her arrow. Inuyasha and Chokyūkai battled each other briefly before Kagome shot her arrow at Chokyūkai with the sutra attached to it. It landed on his behind and caused him great pain. He left his palace after generating a twister to escape. Inuyasha and the others were then able to free all of Chokyūkai's wives.
