Yap

Yap (138.076E 9.486N) is an island group at the northwest edge of the Carolines.  It had been moderately developed by the Japanese and had an important airfield.  Geographically, Yap consists of a large, hilly main island and a number of islets.  Its native culture is most distinctive for its ancient practice of using very large stone disks as money.

The island was struck by American carrier aircraft from Reeves' task group on 31 March 1943, during the raid on the Palaus, but damage was relatively light. An invasion of the island was considered, but in the end it was bypassed in favor of Ulithi.
