The plant is divided into separate areas according to the production process, including weighing, filling, packaging, and packing. Strict environmental sanitation control is performed in each area.

Ryukakusan began cultivation of indigenous herbal medicinal plants in Japan

Ryukakusan is promoting the cultivation of herbal medicinal plants in the towns of Misato and Happo in Akita Prefecture. Our aim is to achieve a stable supply of domestically produced superior-quality herbal medicines, while making effective use of and rejuvenating under-utilized property such as fallow fields.

Herbal medicinal plants cultivated in Akita, a region richly endowed with nature, are incorporated into Ryukakusan's products.

We also support local production of Japanese herbal medicinal plants and herbs through the special regional revitalization tax system in the towns of Misato and Happo in Akita.

Overseas expansion since around 1950

Ryukakusan has a long history of overseas expansion, beginning with the export of our products in around 1950.

We continue to develop our business from a global perspective, having obtained patents in Japan, Asia, the United States, and Europe, and having secured the Ansan Factory of Boryung Pharmaceutical Co., Ltd. in South Korea as an overseas manufacturing site.

Contribution to society through community-based activities

Ryukakusan values its connection with the community in which its head office has been located since the Meiji period.

Once every two years, on the occasion of the Kanda Festival, a mikoshi (sacred religious palanquin) from the neighborhood association (Higashi Kanda Toshima-cho) is displayed in the entrance hall of the head office.
