Kagamino City is a population center of unknown size located in Japan in the Human World. It is situated 22 km east of Karakura Town.

When Sōsuke Aizen invades Karakura Town, the Reiatsubeing emitted from the combined armies of Aizen and the Shinigami could be felt in Kagamino City, despite the large distance between the two areas. At this time, there are a number of normal Hollows roaming the town, pursuing a Plus. Some of the Hollows are crushed under the weight of the Reiatsu.

Eikichirō Saidō is charged with protecting Kagamino.
