Even though Kasturen's dig got underway in 2013, the coins weren't found until 2016. Chinese coins and ceramics were among the other objects discovered; they were obtained through trade with China. Regarding the Roman and Ottoman coins, archaeologists are perplexed as to how those made their way into a castle like one in southern Japan, like Kasturen.
