National Mochi Day is celebrated worldwide every August 8, honoring the popular Japanese rice cake known as mochi. This unofficial food holiday was established in 2021 by Mochi Mochi Wagashi, a Hawaii-based mochi business, to promote the deliciousness of mochi and support their new venture. Mochi, made from glutinous japonica rice, is traditionally prepared by soaking, steaming, and pounding the rice into a sticky mass. It can be enjoyed in various forms, such as daifuku, which is mochi filled with sweet ingredients, or as part of soups like zōni. The holiday encourages people to indulge in different varieties of mochi or try making it at home, and participants often share their experiences on social media using the hashtag #NationalMochiDay.
