Usuki Castle

A 'sea castle' (海城) built by Otomo Sorin on a peninsula jutting into Usuki Bay in Oita in 1556. Sorin was a Christian daimyo who received the first Portuguese ships here. The stone walls above the harbor and the famous Usuki stone Buddhas (National Treasures) nearby make this a unique historic site.
