SE Asia? Looks like the typical WW2 type of airstrip built after an invasion in those areas.
Lots of sand.
Suprising how many you see flying in Burma ( Myanmar ), Borneo ( Malaysia ) or other places. Near one place in Burma where I worked there was a WW2 Japanese strip near the beach. Never got a chance to land and explore. Did some very low and slow passes with the helicopter.
