Nishihara (西原町, Nishihara-chō, Okinawan: ニシバル, romanized: Nishibaru[1][2]) is a town located in Nakagami District, Okinawa Prefecture, Japan.

[3] The north, west, and south of Nishihara are hilly; these areas give way to the low-lying coast in the east of the town.

Untamamo was the site of fierce fighting during the Battle of Okinawa in World War II; the spontaneous combustion of unexploded ordnance caused numerous mountain fires in the post-war period.

It was near the village of Nishihara that the U.S. 1st Marine Division reached its initial invasion objective on April 4, 1945 during the Battle of Okinawa.

The entirety of Nishihara was destroyed as a front line in the battle, and its residents fled to the north and south of Okinawa Island.
