I(Uchiumi) made my first live performance on the radio station: FM Wing on June 9, 2018 (Saturday). When I entered the studio, my tension was so high that my heart almost popped out of my mouth. However, despite knowing my trouble, the host, Mr. Okawara, was calm and asked many questions in quick succession. I explained about my company, about the world's first septic tank that can purify milk, and about the hypochlorous acid water called CLEAN·REFRE that can safely disinfect. Thank you for giving me a good experience.
