A Japanese consumer health and beverage manufacturer producing supplements and functional drinks under the brand Akan, formulated specifically for people who flush red when drinking alcohol. The company frames the category distinctly from hangover products, arguing that hangover remedies support the following day while its own products are intended to be taken before or during drinking, taken much like an aperitif ahead of a meal or business entertainment. The line spans a soft drink (seiryo inryosui), yeast-extract-containing foods, a nutritional or energy drink including a white peach flavour, and a portable Akan To Go supplement format. Formulations are built on licorice extract, cysteine peptides, amino acids, quercetin, alpha lipoic acid and B and C vitamins, with a reduced-sugar position relative to comparable drinks. Products are described as made in Japan and manufactured in Gifu Prefecture using selected Japanese-origin raw materials developed over years of research, with plant-derived, natural-origin and caffeine-free positioning. Marketing material cites the prevalence of the alcohol flush response across East Asian populations - roughly 45 percent in Hong Kong, 42 percent in Japan, 32 percent in Korea and 27 percent in China against effectively none in the United States - and lists associated symptoms such as headache, drowsiness, raised body temperature, reduced concentration, palpitations, hives, dizziness and nausea. Distribution is direct through the company's own online shop plus the Amazon, Rakuten and Yahoo marketplaces in Japan, and the site carries an extensive FAQ covering allergens across the 28 designated categories, storage, dosing occasions and interactions with medication, alongside a customer referral program and an art section.
