# Prachuap Khiri Khan

Prachuap Khiri Khan (Thai: ประจวบคีรีขันธ์, pronounced) is a town in western Thailand. It is the capital of Prachuap Khiri Khan Province and is on the coast close to the narrowest stretch in Thailand, only 10 kilometres (6.2 mi) from the border with Myanmar at Dan Sing Khon in the Tenasserim Hills. The area has large pineapple and coconut industries, in addition to being popular with Thai tourists. The town is 291 km south of Bangkok by road.

## History

Prachuap Khiri Khan is home to a Royal Thai Air Force base, and was an invasion point for Japanese troops on 8 December 1941, during World War II. A commemoration is held each December to honour the 38 Thai airmen and civilians who died in the fighting against the Japanese 143rd Infantry Regiment in the Battle of Prachuap Khiri Khan.
On December 5, 2023, a double-decker bus carrying mostly Thai nationals veered off the road and crashed into a tree, which resulted in 14 deaths and 32 injuries.
