Seireitei is in the center of Soul Society. Seireitei is a circular shiro with four main entrances, ten days walk apart, each guarded by one of the Gatekeepers. These gates are collectively called the Four Great Pure Soul Gates: these gates are made up of the Northern Black Ridge Gate , the Eastern Blue Stream Gate, the Southern Red Hollow Gate, and the Western White Way Gate. The walls of Seireitei are made of Sekkiseki, a rare type of stone known to negate all Reiryoku, similar to magnetic lodestones. The stone also forms a spherical barrier around the city, extending above and below, stopping anything spiritual from breaching it from ground level, from the sky or from underground. The wall that surrounds the Seireitei is commonly held up, only closing down when there is an emergency. When it is not down protecting the Seireitei, the wall protects the Soul King Palace, located in an inner dimension.

An unchanging night covers the sky, an endless white desert covers the ground. The tree-like objects are not plants, but rather quartz-like minerals. The landscape of Hueco Mundo is a seemingly never-ending white desert, with a multitude of dunes, littered with boulders. In Hueco Mundo, the moon is on the opposite lunar phase of that in the Human World. The vast desert seems to lack any bodies of water and contains rocky formations. Like in Soul Society, the atmosphere is filled with a high concentration of Reishi, thus allowing smaller Hollows to gain nourishment despite the lack of Human souls.

The Forest of Menos is an area below the surface of Hueco Mundo's desert where the average Hollow hide from the Arrancar. The forest is filled with large trees made of a silvery quartz substance. These trees extend to the surface and dot the landscape of the desert in Hueco Mundo.
