However, they do visit a Moon Kingdom in the anime, which is a realm separate from Earth. This occurs in the "Sailor Moon R" season, specifically during the "Black Moon Clan" arc.
Here are some details about this trip:
* Episode: The Moon Kingdom is introduced in Episode 92 ("The Moon Princess's Message") and they spend several episodes there.
* Purpose: The Sailor Scouts go to the Moon Kingdom to meet Princess Serenity and learn more about their past lives. They also need to fight the Black Moon Clan who is trying to conquer the Moon Kingdom.
* Context: The Sailor Scouts discover they are reincarnations of the Sailor Guardians from the Silver Millennium, a time when the Moon Kingdom ruled peacefully over Earth. The Black Moon Clan is a group of enemies from that time who are seeking revenge.
While the Moon Kingdom is a different place than the actual Moon, it plays a significant role in the *Sailor Moon* story, especially in the "Sailor Moon R" arc.
