Ryukakusan Co., Ltd. (株式会社 龍角散, Kabushiki-gaisha Ryukakusan) is a Tokyo-based Japanese pharmaceutical company that develops and markets prescription and over-the-counter drug (OTC) products, especially throat and swallowing products.[1]


In early 1700s, “Ryukakusan” was a family powdered herbal cough medicine handed down through generations of the Satake clan of the Akita Domain.[2][3] Shoteiji Fujii began selling it as medicine for the public in 1871.

In 1995, the company had a ¥4 billion debt. They recovered from this by selling Iatron Laboratory to Mitsubishi in 2002.[4]

Ryukakusan's products are popular in China and Taiwan. Tourists buy their products in bulk to bring home when they travel to Japan.[4]
