Sanyo Onoda City has long had a thriving ceramics industry that uses kiln to process clay and other non-metallic inorganic materials at high temperatures to produce ceramics, glass, cement, enamel, ironware, and bricks. In the Dan area, the soil produced in the area was suitable for manufacturing sulfuric acid bottles, so from the Meiji period to the Showa period, the production accounted for 70% of the domestic market share. The bottle fence used the non-standard bottles that came out at that time. In addition to sulfuric acid bottles, shochu bottles and unglazed bowls were stacked and embedded to create the unique landscape. Look for it when walking around the town of Sanyo Onoda.
