After my talk today, I drove up to Katsuren-jo, one of many Ryukyu castles on Okinawa, dating to the 15th century. This one has the added bonus of turning up a small hoard of fourth-century Roman coins, which was in the news a while back. A cool mystery!
View of the central fortification, Katsuren-jo, Okinawa Outer fortifications, Katsuren-jo, Okinawa Museum display of fourth-century Roman coins discovered at Katsuren-jo, Okinawa Museum display of foreign coins found at Katsuren-jo, Okinawa. Google Translate of main label in Japanese: “A total of 10 Western coins were discovered in the fourth enclosure and outside the castle. Nine are believed to be Roman Empire coins, and the remaining one is thought to be an Ottoman Empire coin minted in 1687, but the circumstances of how these coins came to Katsuren Gusuku are unknown”

One way we can reconstruct ancient trade networks is via the presence of foreign coinage. This map shows locations of recovered coins of /purported/ Roman lineage.

In 2013, on the island of Okinawa, 4th-century AD Roman bronze coins were excavated from the ruins of Katsuren Castle.
A crude relief/ecology map of Eurasia and Northern Africa, showing the location of Roman coinage (purported, many of these were amateur finds never confirmed), and the concentrations are in Europe, the Nile and India, with some coins in China, Vietnam and Japan.

I knew that the Japanese archeologs had found Roman coins in Katsuren castle in Okinawa. I was not aware that one was an Ottoman coin c.1687.
Looks like a copper mangir of Süleyman II.

Rabbithole tangent:
Katsuren Castle (勝連城) was the home of the 15th Century Ryūkyūan lord Amawari (阿麻和利)
en.wikipedia.org/wiki/Amawari (see ja page for more info) who apparently was instrumental in promoting European in the area. The coins may have been a collector’s item back then.
