Source-derived summary

Shimotabaru Castle (下田原城, Shimotabaru-jō) is a Ryukyuan gusuku fortification located on Hateruma Island in the Yaeyama Islands (Taketomi, Okinawa Prefecture). Nanjō, Okinawa. The castle ruins were designated a National Historic Site in 2003.

History

Around the end of the 12th century, the development of increased trade with Song Dynasty China and other countries led to the emergence of a ruling class. Many warlords ruled over the Yaeyama Islands until the Oyake Akahachi Rebellion, led by Oyake Akahachi, a native of Hateruma Island, brought the islands under the control of the Ryukyu Kingdom in 1500. Although small in size, Hateruma Island is dotted with fortification ruins and other remains believed to date from this period. One such example is Shimotabaru Castle, located on a cliff about 25 meters above sea level near Odomari Beach in the northern part of the island. Based on the discovery of Chinese celadon ware fragments dating from the 15th to 16th centuries, Shimotabaru Castle is believed to have been built around this time, but the exact date and who built it are unknown.

Shimotabaru Castle measures 150 meters east-to-west and 100 meters north-to-south. Surrounded by cliff walls made of piling coral limestone, it comprises eight enclosures.

Editorial analysis

Why this record matters

The phrase “ryukyuan gusuku in Taketomi, Okinawa Prefecture” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q11361159. Authority coordinates are 24.069, 123.778. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2003 and 1500.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
