Temple's Platform

The Temple Platform is a platform that is in orbit above the Earth and more specifically the Land of Mountains. Events occurring on the earth can be observed from here. Only the Yamakage and his close friends and relatives are allowed here. When Ryun became the 10th Gokage Sennin, it was renamed Gokage's Lookout Temple.

Teleporter
It is also revealed that the Lookout has a teleporter or transporter machine that allows Kami or anyone to go wherever they want to on Earth. Ryun is rarely shown using this, but the most notable case was in The Great Shinobi World War during the initial struggle with Seireitou Hyuga.

Training Chamber
A room featured prominently, it is in a different time dimension, where a day outside is a year inside (or one minute outside is just six hours inside). Supposedly the room can only be used for up to 48 hours outside the chamber in one lifetime. If one were to break that rule, the doorway to the outside world would automatically vanish, thus trapping the trainee(s) inside for eternity. Ryun alleged that only two people can enter at a time, however this was proven false, as Sanji, Tora, Jessica, and Luke were able to be inside all at once.

Inside the Temple
While all of the above is on top of the temple, there are two different things inside the lookout: The very bottom of the lookout is connected to all the winds of the world, to get there, one must go through a sacred area known as the Shinsenkai where all the past Yamakages of the Land of Mountains exist.

There is a small section that was just empty, allowing trainees to have their battle without harming the Earth.
