History

The name Asa is from the ancestors of the locals in the area which fought Cambodia soldiers during a war.
The history dates to the Ayutthaya period during the reign of King Naresuan. At that time, Cambodia was reportedly allied with Ayutthaya.
When Burmese forces invaded Ayutthaya, King Naresuan led his army to counter the Burmese advance, withdrawing troops through the area of Prachin Buri. The Khmer forces then launched an invasion into Siam through Kabin Buri.
The guards of King Naresuan reportedly mobilized local residents to resist the invasion. Among these were villagers later associated with Asa subdistrict, who migrated from Vientiane.

The tambon is divided into eight administrative villages.
