The operation of Japan’s first steelworks began in Kitakyushu and the city prospered as a steel town. In 1960’s Kitakyushu faced serious pollution, causing “Sea of Death”. In the morning of the Day 3 we visited the Higashida Daiichi(No.1) Blast Furnace, a historical site symbolising Japan’s industrial revolution, and at the Kitakyushu Innovation Gallary & studio near the site the participants saw a documentary on Yawata Steel Work, whose historical facility is one of a series of the component parts of a UNESCO World Heritage. Then it was followed by a very impressive study tour to the Kitakyushu Environment Museum, which shows the history of the city overcoming severe environmental pollution. In the afternoon, we had a lecture on the development of Higashida region, where the “Kitakyushu Smart Community Creation Project” was conducted. We walked around the area, ending with a demonstration of how a hydrogen car can lighten up an eco-friendly house.
