Getting connected with international audio researchers after a solo exhibition in Paris. After participating in the ETF (European Triode festival) in 2014 as a Japanese team, I developed the first ceramic speaker based on the advice of my teammates. This is the beginning of my challenge. The speaker was covered by a European audio magazine (stereo) and became known by audio researchers around the world. In 2016, the Japan team hosted an event in Fukuoka and invited around 60 audio researchers, during which I built an audio house as one of the venues to further hone my studies on materials and my sense of sound. In 2017, Why do pottery speakers have excellent sound quality? To answer this question, we conducted research in collaboration with Professor Omoto of the Faculty of Acoustics Design of Kyushu University and the Fukuoka Prefectural Industrial Technology Center, demonstrating that sound quality is strongly correlated to the characteristics of Takatori Pottery. As a result, the Ministry of Economy, Trade, and Industry recognized the unique qualities of this item and certified it in its project to utilize regional resources. Currently, Takatori ware pottery speakers have gained the opportunity to be announced all over the world, and the number of fans has been increasing steadily, not only among acoustic professionals but also general customers, we have started cooperating with various companies in the sound production business. By challenging ourselves to enter a new field, we have created many new connections and could see a new future. I want to share the importance of challenging ourselves with everyone.
