The village was historically a farming community but today is mostly residential. During World War II, the Japanese forced the indigenous Chamorros to march from camps in northern Guam to prison camps in the Manenggon area in Yona shortly before the Americans liberated the island. Japanese tanks in the area near the Segua river serve as reminders of the war.
The municipality of Yona has an area of 20 mi² (52 km²) and is located on the eastern side of Guam between Pago River and Togcha River. The village center is located above the cliffs between Pago Bay and Ylig Bay. Residential areas of Baza Gardens and Windward Hills are located to the south.
