When you said Kasongan it mean sentral of handycrafts and ceramics industry that located in Jogjakarta, it was inside the territory of Bantul regency, is about 7 kms from Jogja. Beside farming, the villager made a handycraft and ceramics and they sold their product on their gallery. Some product in various kind and size made to export. There is so many gallery on the left and right side of Kasongan street and it is easy to go there by public transportation.
Here you can buy, product from wooden, stone, leather, from banana tree and many kind of material that sometimes is very difficult to realize "what material is this". For the people who realy like to shop, this is one of the place at Jogja, that you wouldnt like to miss it.
