Minamikarasuyama borders Kasuya and Kamisoshigaya to the south, Kyūden to the west, Kitano in Mitaka, Kitakarasuyama to the north, Muri in Suginami, Kugayama and Hachimanyama to the east.
The southern part originated from a village along the Kōshū Kaidō, and the northern part was mainly triggered by the following "Karasuyama Temple Town". For this reason, the northern part has different characteristics from the area around Chitose-Karasuyama Station, such as some facilities called "Kugayama" and "Mitaka".
