Founder's story

As a young child, Koko Hayashi spent a lot of time with her grandmother. “I remember this one time I invited my friends over to play, but they told me they didn’t want to come because of my grandma,” Koko recounts. “They told me it was because my grandma smelled bad, which seemed silly to me.” As Koko said, it’s hard to hear anyone say something negative about your loved ones.

Koko grew increasingly interested in the beauty and health industry as she got older, especially because she had heard stories about people not visiting their elders because of the way they or their homes smelled. “This was very saddening to me,” Koko said. “They were missing out on time with their family I often thought. It was then I realized maybe that’s what my friends had been talking about all those years ago…” We crave relationships at all stages of life, and to know a certain smell may be keeping people from visiting someone they love… that’s hard to hear.

This led Koko on a mission. “I read and learned more about how others perceive the smell and it turns out that ‘old person smell’ is something we’ve learned to associate with older adults because it typically doesn’t present itself until later in life,” Koko mentions. One day, she was introduced to the Japanese company Shiseido and one of their experiments. In this, they found that “we produce a distinctive odor that is similar to that of an onion… when we come under stress” (read more

“In Japan, there is a day to recognize and respect those that are older, referred to as ‘Aged Day’, and I spent every “Aged Day” that I could with my grandma,” Koko said. It was this respect and honor she saw in Japan and the love for her grandmother that she wanted to share with the United States. “I wanted older adults to feel loved and confident again, so I founded Mirai.”

Mirai is built on the belief that our elders should be respected. It is backed by a fine selection of natural ingredients that work to effectively fight a problem that not everyone may experience but for those that do, will be grateful for.


It's all in the science

Since Shiseido’s discovery, other scientific studies have continued to show that body odor does indeed change with age. Thus, there is a body odor associated with aging. This knowledge is common in Japan but known very little elsewhere. Even though baby boomers are booming, this issue has been ignored for a long time... until now!

What can eliminate an odor that isn’t as easily washed off regardless of good hygiene or daily bathing? Japanese Persimmon! Not all Persimmon Extracts are alike though. Only extract that has been specially grown, selectively harvested, carefully processed, and tested for maximum deodorizing benefits demonstrates the results we look for. Our Persimmon Extract is formulated in our partner lab following these conditions and under Good Manufacturing Practices (GMP) in addition to ISO9001.
