Kukuroo Mountain (ククルー=マウンテン, Kukurū Maunten) is a dormant volcano located in Dentora Region of the Republic of Padokea.
It stands 3,722 meters (approx. 12,211 feet) above sea level, and is where the infamous Zoldyck Family lives. The family owns the mountain and the land around it is surrounded by huge stone gates.
The foot of the mountain is covered by a dense jungle and typically surrounded by thick clouds. It's said that the Zoldyck mansion is on the peak of the mountain. The Zoldyck Family's yard encompasses the entire area, starting from the Testing Gate up to Kukuroo Mountain.
