There’s something that a lot of people, especially older adults, can experience called “old man smell,” or in Japan, it’s referred to as “Noni Nao Body Odor.” It tends to show up in people after they reach about 40 years old. Regular deodorants often don’t work for this smell, which is a big issue that many people don’t really talk about.
Koko, who is connected to something called Face Yoga, had a clever idea to help with this problem, so she went on a show called Shark Tank to get support for her new business. Her company is called Mirai Clinica, and she created special products using a fruit called a persimmon. Persimmons are super helpful because they can actually get rid of that old man smell. Koko made different products like soaps, wipes, and deodorants that contain persimmon.
When Koko was on Shark Tank, she asked for $500,000 in exchange for 5% of her company. She showed the sharks how much money she was making with her products. Some sharks thought her idea was funny, while others weren’t sure if enough people would want to buy products for this specific smell issue.
Mirai Clinical Net Worth Shark Tank Update
Koko Hayashi asked for a $500k investment in exchange for 5% equity in her company. This meant she valued her company at $10 million. She did not get a deal from any of the Sharks, so the original valuation stayed the same. After the show aired, Mirai Clinica saw a big increase in website traffic, sales, and social media exposure. With an estimated 10% yearly growth rate (typical business growth), the current net worth of Mirai Clinica is about $14.65 million.
Mirai Clinica is still doing well despite facing some challenges. After appearing on Shark Tank, the founder, Koko, focused on selling products online, primarily through Amazon and her own website.
As of today, Mirai Clinica continues to sell its products, even though there was a minor setback known as the “body wash heist.” Koko has moved on from this incident and remains committed to her company’s mission. The brand may not be large, but it has a dedicated group of customers who are loyal to it.
Koko also uses social media to advertise her products and allocates about 30% of her income to these ads. The return on ad spend (ROAS) is 2.5, meaning that for every dollar spent on advertising, she earns $2.50 back. While the business may not be enormous, it is stable and continues to grow.
No, Koko did not get a deal. All the Sharks said no. They had different reasons. Some didn’t believe in the product. Others thought the valuation was too high.

Mirai Clinical Shark Tank Pitch
Koko started a company called Face Yoga, where she helped people look younger by showing them how to do facial exercises. While doing this, she discovered a unique smell called Noni Nao from Japan. Noticing that there was a need for products that could help with unpleasant odors, she decided to create a new line of products called Mirai Clinica. The main ingredient she focused on was persimmon, which has special properties that can absorb bad smells.
Koko developed soaps and wipes using this ingredient. However, the beginning of her journey wasn’t easy. She had to bring everything from Japan, which made things challenging. At one point, her body wash was even stolen! Despite these difficulties, Koko remained determined and believed in her vision, which kept her moving forward.
Koko entered a pitch meeting confidently, aiming to present her innovative product line to the Sharks. She first introduced a unique scent called “Noni Nao,” which didn’t sit well with the Sharks; they found it unappealing.
After addressing the scent, Koko introduced her products designed to combat the unpleasant Noni Nao smell. She explained that her products, which include soap wipes and deodorant, are formulated with persimmon, a fruit known for its ability to neutralize the specific odor associated with Noni Nao.
Koko was seeking $500,000 in exchange for a 5% ownership stake in her company. To back up her request, she shared impressive sales figures, revealing that her business made $2.2 million in sales the previous year. However, she mentioned that this year has been tougher for her business due to a robbery, referred to as “the heist,” which likely impacted her performance and operations.
Barbara Corcoran asks how much money Koko made from selling her product last year. Koko explains that she made $2.2 million last year. She adds that if something bad (called a heist) hadn’t happened, she could have made $4 million this year. A heist usually means a robbery or theft, so it impacted her sales.
Robert Herjavec wants to know how Koko is selling her product. Koko tells him that she sells everything online—which means people can buy it through her website and Amazon.
Barbara Corcoran asks about Koko’s advertising costs, meaning how much money she spends to promote her product so people will buy it. Koko replies that she spends 30% of the money she earns on ads, specifically on Facebook ads.
Kevin O’Leary questions whether people could just use regular soap instead of Koko’s special soap. Koko responds that regular soap doesn’t work well enough to get rid of a bad smell called Noni Nao.
Lori Greiner adds to Kevin’s question by asking why normal deodorants don’t work for the same smell. Koko explains that many American products don’t test for Noni Nao, meaning they haven’t been made to specifically fight that smell.
Mark Cuban asks how much it costs Koko to make her soap. Koko responds that it costs her $1.85 to create one bar of soap, but she sells it for $17. This shows that she makes a good profit on each bar sold.
Mark Cuban: He thought Koko’s idea was interesting but didn’t think it was the right fit for him personally. So, he passed on the investment.
Lori Greiner: She didn’t agree with the idea that everyone over 40 smells bad. She felt this point was unfair and didn’t want to invest because she didn’t think it represented reality.
Barbara Corcoran: She didn’t believe that the problem Koko was trying to solve was a real issue that many people cared about in the United States. Because of this, she decided not to invest.
Kevin O’Leary: He thought the financial numbers around the idea were too unrealistic or crazy, which made him uncomfortable with investing. So, he also passed.
Robert Herjavec: He thought Koko was smart and had potential, but he felt that the price or value she wanted for her business was too high for him to consider investing.
Overall, each Shark had a different reason for saying “no,” which means they didn’t see enough potential in Koko’s idea to put their money into it.
What Went Wrong With Mirai Clinical On Shark Tank?
Sharks had three big worries about the product. The Sharks didn’t think that a lot of people in America would actually care about how “Noni Nao” smells. They were unsure if there were enough customers who would be interested in buying it. The creators of “Noni Nao” wanted the Sharks to invest in their product at a value of $10 million. The Sharks believed that was too high. They thought that the product wasn’t worth that much money yet.
The Sharks believed it would be tough to convince people to buy “Noni Nao.” If it’s hard to market something, it might not sell well, and they didn’t want to invest in a product that might not succeed. Because of these three concerns, all the Sharks decided to say “no” to investing in “Noni Nao.”
