[2] Japanese soldiers landed on Agho during World War II, although they did not stay as they had a garrison in nearby Bagungon Island.

This couple, variously American[2] or Australian[3] and named as Thomas and Terry Cook[2] or Kurt,[3] hired locals to build a cottage on Agho.

[3] Tensions between the couple and the locals grew and eventually the authorities were called in.

On 19 August 1988, Narcom (Philippine Drug Enforcement Agency) found 1,000 plants on the property that were believed to be cocoa plants, although some officials disputed this claim.

[3] The couple had left the island two years earlier,[3] after Marcos's fall from power.
