UNESCO World Heritage Site: Government Silk-Reeling Factory Supporting Japan's Modernization
About this spot
Established by the Meiji government in 1872, this was Japan's first full-scale government mechanical silk-reeling factory. Built with French technology, the red-brick filature buildings and massive timber-and-brick cocoon warehouses remain nearly unchanged since their construction. Designated as a UNESCO World Heritage site in 2014 as part of the "Tomioka Silk Mill and Silk Industry Heritage Sites," walking the expansive grounds offers a hands-on sense of the industrial history supporting Japan's modernization—ideal for family learning.

富岡市大島地区で、お盆に迎えた先祖の霊を送るために古くから受け継がれてきた伝統行事です。集落を見下ろす山の斜面などに一斉に火が灯され、夜の闇の中に炎の明かりが連なる光景は、大きな都市の花火とはまた違った、里山ならではの静かで荘厳な美しさがあります。地域の人々の手によって代々守られてきたこの行事は、規模は大きくないものの、地元の夏を締めくくる大切な行事として親しまれています。
