Utilizing crops of MIyako Island

Do you know a plant called ramie? It can be found anywhere in the world, and belongs to Arabesque family.
Miyako Joufu – a fine hand woven cloth which is made from the fibers of ramie plant is famous product of Miyako Island. Ramie has very thin fibers, so that Miyako Joufu is very thin as well. Due to its thinness, it requires slow weaving process or the thread is easily cut. Therefore, it takes approximately three months to make 1tan (enough to make one kimono). In addition, they have a special way of making patterns. While ordinary cloth is made by weaving dyed threads and non-dyed threads to make patterns, Miyako Joufu dyes each strand of thread with white and indigo blue and weaves them to make patterns. This is made by combining threads for weaving and whitening to dye the threads.

Crops for ecological activities

As written above, apple mango and Miyako Joufu are not only sold in the market, also used as rewards of hometown tax payment system. Part of the tax revenue will be used to promote ecological activities.

Summary of Geography– future issues

Miyakojima City is sparsely populated, and birthrate is declining and population is aging. Whereas we learned that it is a suitable location to grow sugar cane which requires vast land, and to raise Miyako horse. How do we improve issues around the low birthrate and aging population? How can we utilize the vast land of Miyako island? We think this will be the future problem.
