Zakimi Castle (座喜味城 Zakimi jō?) is a gusuku in Yomitan, Okinawa Prefecture, Japan. It is in ruins, but the walls and foundations have been restored. It was built between 1416 and 1422 by the renowned Ryūkyūan general Gosamaru, a project which involved workers from as far away as the Amami Islands, and was partly constructed with materials taken from nearby Yamada Castle. Zakimi Castle oversaw the northern portion of cental Okinawa Island. The gusuku fortress has two inner courts, each with an arched gate. This is Okinawa's first stone arch gate featuring the unique keystone masonry of the Ryukyus.
Before and during World War II, the castle was used as a gun emplacement by the Japanese, and after the war it was used as a radar station by the US forces. Some of the walls were destroyed in order to install the radar equipment, but they have since been restored.
