However, Cashi Cake's story begins when she lost a relative living in the U.S. to diabetes. In Japan, there is medical evidence that seaweed is effective against developing type-2 diabetes, but it is not easily accessible worldwide. To combat this, Alissa founded the Marine Plant-Based Technology Company that would evolve into today's Cashi Cake in September 2019. Purposing the world's most advanced blue carbon and marine plant processing technology to promote health and longevity, Cashi Cake Inc. develops food products, alternative plastic containers, and medical capsules.

One of our most well-known brands is Misaky.Tokyo, which combines contemporary marine plant-based wellness and traditional Japanese confections into inspired treats. Misaky.Tokyo has collaborated with Kim Kardashian, whose audience includes a massive 1.9 million TikTok followers. The brand has also gained over 1.4M followers and 650M views on TikTok and has catered PGA Tour, Academy, and Emmy Awards pre-events.

In October 2023, Cashi Cake Inc. filed a joint patent application with the Tottori Industrial Technology Center in Japan for the world's first successful method of packaging high-ABV beverages with marine-plant-based materials.

In 2024, Cashi Cake plans to launch OoMee, the world's first functional seaweed beverage in retail stores. OoMee was selected as a finalist for best new plant-forward product at the 2023 Expo West NEXTY awards, the largest food trade show in the U.S.

Outside of her accomplishments with Cashi Cake Inc., Alissa is active as an influencer and television personality in Japan and the U.S. She is the first Japanese woman to be selected for the U40 Program of the Milken Institute, the largest economic conference in the U.S. Alissa is also a news commentator on the television news show “Bankisha” viewed by over 15M Japanese people annually.
