Limbuwan is an area of the Himalaya historically made up of 10 Limbu kingdoms, all now part of Nepal. Limbuwan means "abode of the Limbus" or "Land of the Limbus". Limbus themselves call Limbuwan "Yakthung Laaje" or "the country of the Yakthungs" (see History of Limbuwan).
Today, Limbuwan comprises the districts of Taplejung, Panchthar, Ilam, Jhapa, Terhathum, Sankhuwasabha, Dhankuta, Sunsari and Morang. Limbuwan is the land east of the Arun and Koshi Rivers and west of Kanchenjunga Mountain and the Mechi River. The seat of power in Kathmandu and western Nepalese refer to Limbuwan as the Pallo Kirant region or far Kirant, due to its distance from Kathmandu.
