When hearing about Nakanojo’s modern industrial history, everyone envisions sericulture. However, considering the rise and fall of sericulture from the Meiji era to the Showa era, it can be said that sericulture could not be modernized. I found what modern civilization left behind in the sericulture industry. The content went beyond the framework of Nakanojo and became an image of the civilization that surrounds us now. So to speak, it is a “civilization theory from the perspective of the sericulture industry, including Nakanojo.”
