Country whose name can be typed on just the top row of a keyboard (4)

I believe the answer is:

peru

(Other definitions for peru that I've seen before include "Country of Lima, Cuzco and Paddington Bear" , "Mario Vargas Llosa's native land" , "South American state" , "Andes republic" , "Mario Vargas Llosa's country" .)

I've seen this clue in The New York Times.
