三宅島の主要産業は何？
Miyako-jima is home to sugarcane cultivation, and produces brown sugar. "Miyako jōfu" is a locally produced hand-woven textile made from ramie fiber. It was formerly known as "Satsuma jōfu". The textile traces its production to the Tensho period, 1573-92. The city has seen a tourism boom initially with locals and Taiwanese in the early 2010s, but since 2016 is struggling to cope with cruise megaships from mainland China, but the port can only handle ships as large as 50,000 tons, eventually they hope to service ships as large as 200,000 tons. However, this may change the character of the island as its population is small and rural.
