There are other types of traditional money, but Yap is most famous for its stone money. During the Japanese occupation, however, to encourage the Yapese to work, some of the stones were crushed and used for roads. Ghosts or spirits are often talked about. Long ago, people thought others had the power to send storms and typhoons. Scuba diving in the warm, clear waters is a big draw for tourists.
Divers come to see the manta rays, turtles, sharks, corals and fish.
Yap Day is March 1. It is an official holiday marked by a festival of food and dance. Knowledge is valued and not easily shared. Being indirect is preferrable to confrontation. Change is not done quickly.
