Isara Tocha was one of the 77 woredas in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. Part of the Dawro Zone, Isara Tocha was bordered on the south by the Omo River which separates this woreda from the Gamo Gofa Zone, on the west by the Konta special woreda, on the north by the Gojeb River which separates it from the Oromia Region, on the east by Mareka Gena, and on the southeast by Loma Bosa. Towns in Isara Tocha included Bale and Tocha. Isara Tocha was separated to Isara and Tocha woredas.

Isara Tocha is part of a region characterized by hills, and is not suitable for grazing or cultivation, but farmers cultivate the sloping land, leading to erosion and reduced soil fertility. Important food crops in this woreda include enset, sweet potatoes, taro and beans, while important cash crops are maize, teff and pulses.
