慶良間群島
Zamami emerged under the Ryukyu Kingdom as the Jiyaman magiri. The magiri was a type of regional administrative district in Okinawa in the pre-modern period, and Jiyaman magiri, together with Tōkashichi magiri, controlled the Kerama Islands. Zamami was noted for its excellent port, and due to its proximity to Okinawa Island, was used as a port for trade with China during the fourteenth century. The Chinese vessels would stop in Zamami Island’s Ago-no-Ura bay to wait for favorable winds before proceeding on toward China.
