Founded in 1871, Ryukakusan is one of Japan’s most iconic throat care and herbal medicine brands, best known for its herbal throat powders, lozenges, and cough relief products. The company’s origins trace back to the Edo period, when the Fujii family served as physicians to the Akita domain and developed traditional herbal remedies using a blend of Japanese and Western medical knowledge. Over generations, the formula evolved into the modern Ryukakusan products that are now widely recognized across Asia for soothing sore throats, coughs, and vocal strain.
Today, Ryukakusan remains a family-led Japanese pharmaceutical company headquartered in Tokyo, combining centuries of herbal medicine heritage with modern manufacturing and research facilities. Its products, especially the famous Ryukakusan throat lozenges and herbal powders, are popular among singers, travelers, office workers, and consumers seeking gentle, herbal-based throat relief. The brand has also gained a strong international following where its products are often viewed as trusted Japanese wellness essentials.
