Koko Hayashi founded Mirai Clinical in 2014 after noticing the problem of a special body odor called nonenal, which happens as people age. She saw this issue when living with her grandmother, whose body odor made visitors uncomfortable. Koko learned that persimmon extract can remove this odor, which regular soap cannot.
Mirai Clinical’s most famous product is a persimmon soap that effectively removes the nonenal odor, helping people feel clean and confident as they get older. Koko appeared on Shark Tank Season 16, Episode 19, to promote her business and ask the Sharks for investment to grow her company.
The company focuses on natural, science-backed skincare products free from harmful chemicals, targeting age-related body odor. Mirai Clinical sells its products online and has gained attention for its unique solution to this common aging problem.
