Ryukakusan company was established in 1928 under their co., ltd name. In addition to selling its main commodity, "Ryukakusan powder," it exported technology to Asian countries and carried out various businesses.

After that, they carried out unique research on throat medicine and successively developed a variety of tablets, powders, buccal tablets, and other products in the name of Ryukakusan powder.
