https://prcdn.freetls.fastly.net/release_image/25517/801/25517-801-bbf99c92df922d544059a85c521719a9-1280×853.jpg While many people feel that “reducing salt intake is bland” or “unsustainable,” Ayana Kato, with her husband’s health in mind, worked with culinary expert Tsubomi Tamura to create “ice dashi,” a soup stock made with umami instead of salt. The “frozen dashi” made with frozen bonito flakes, sake lees, onions, and ginger was so delicious that even my husband praised it. It was so tasty that he wouldn’t even notice if I told him I’d stopped eating low-salt dishes. Tamachan Shop sympathized with my husband’s passion and ingenuity to support his dream of performing on stage until he was 108 years old, and re-created it as a powdered version that anyone can easily incorporate into their diet: “Ayana’s Low-Salt All-Purpose Dashi Powder.” This low-salt dashi was created after a year of trial and error and is made with the family in mind. ■ Ayana Kato Profile

Their 45-year age difference caused a lot of buzz about their age-gap marriage, but they continue to receive criticism. As a result of her perseverance without arguing in the media or on social media, the way the public sees Kato and the way she is portrayed in online news has changed, and she has been featured on television and in magazines as a devoted and supportive wife, and her lifestyle-focused way of thinking, such as cooking secrets unique to an age-gap marriage and obtaining a nursing care qualification, has attracted attention. ■About Tamachan Shop Enjoy safe, delicious, and nutritious food while staying healthy and beautiful.
