【上山英一郎】人類の命を救った日本の大発明！渦巻型蚊取り線香「金鳥」の誕生と瀬戸内の花畑

The spiral-shaped mosquito coil, a beloved symbol of Japanese summer, is actually a groundbreaking invention that continues to protect people worldwide from infectious diseases transmitted by mosquitoes, the deadliest creatures on Earth. Behind its creation lies the tenacity of one man who faced numerous difficulties, and the deep bond between a husband and wife. Eiichiro Ueyama, the founder of Dainippon Jochugiku, known for its "Kincho" brand, was born into a rural mandarin orange farming family. Inspired by his mentor Yukichi Fukuzawa's teachings of "building a trading nation," he dedicated his life to cultivating the unknown plant, pyrethrum. However, he was met with cruel insults, being labeled a "swindler," and faced the brink of bankruptcy… Seven years of trial and error, and then his wife Yuki's "that one word"—it changed history! Here is the dramatic story of how Japan dramatically improved its sanitation and rose to become the world's leading exporter. This video explores the life and work of Eiichiro Ueyama, the man who confronted this threat to humanity and created the mosquito coil that would ultimately save the world. Please watch until the end.
