Tushita

Tushita, or the Joyous Realm (Skt. Tuṣita; Tib. དགའ་ལྡན་, ganden, Wyl. dga' ldan) — one of the celestial heavens of the six heavens of the desire realm where gods and bodhisattvas reside. It is from this heaven that supreme nirmanakaya buddhas descend to take birth in the world. Buddha Shakyamuni resided there as bodhisattva Shvetaketu (Skt. Śvetaketu) and, before descending to this world, placed his crown on bodhisattva Maitreya's head, inviting him to the throne of Tushita until he takes birth as the future buddha.
