This park, Haniwa Factory Park, is the site of the Shinike ruins, an ancient haniwa factory that has been turned into a park. The Shinike ruins are the site of one of Japan's oldest and largest haniwa factories, where the haniwa for the Imashirozuka Tomb, said to be the tomb of Emperor Keitai, were made. Approximately 1,500 years ago, it was a large-scale facility that was equipped with 18 kilns for firing haniwa, three workshops (workshops), and even residences for the haniwa craftsmen. This park, which preserves and maintains these ruins and opens them to the public, not only has restored haniwa workshops and haniwa kilns that were in use around 450, but also has a Haniwa Factory Museum where excavated kilns are on display as they were, making it hard to believe that it's free to visit.
