Korin Tower (Karin-tō) is a tower on Earth where Master Korin lives. The tower is located in the Sacred Land of Korin and is so tall that it took Goku an entire three days at first to get to the top and get the water from Korin. The Tower's address is FFA 44195 SQ.
The tower was built to honor a great hero (it is never stated who the hero is nor is it known if he was the same being as Korin, but in anime filler it is implied that this hero could have been Olibu). The "Owner", Korin, grows Senzu Beans in the tower, which he gives to the Z Fighters freely whenever he has some in stock, most often via Yajirobe. However, the Japanese version of the movie Dragon Ball Z: Cooler's Revenge implies that Korin can only allow the Z Fighters to gain the Senzu beans if they climb all the way up, and if they only climbed up halfway, he declines the request. In the dubbed version, it is known as the Holy Tower or Korin's Tower; while in the Spanish and Portuguese dubs as Torre Karin (Karin Tower).
