Early 18th century (mid-Edo period)

The Fujii family served as physicians to the feudal lord of Akita domain (domain lord Satake) for generations.

The original form of Ryukakusan was developed by Gen-en Fujii and his son Genshin who came from the town of Rokugo in northern Japan (modern day Misato-cho, Akita). Genshin incorporated knowledge of rangaku (a type of learning that taught about the West, particularly about Western science and medicine) that he had gained into his family's traditional herbal medicine, and the resulting recipe has been handed down through the generations.

The Fujii family is even referenced in the history of the town of Rokugo.

Mid to late 19th century (late Edo–early Meiji period)

During his tenure as physician to the feudal lord Yoshitaka Satake of Akita domain, Shoteiji Fujii (3rd generation) traveled to Nagasaki for a period to study rangaku. His objective was to cure asthma, an illness that plagued his feudal lord.

He is said to have improved the family medicine into an asthma prescription, establishing the foundation of the current formulation.

When the feudal domains were abolished and replaced with prefectures in the late 19th century, the rights to the Ryukakusan medicine that was prepared from the family recipe were granted to the Fujii family.

Shoteiji, who had moved to Edo (present day Tokyo) with his feudal lord, established himself in 1871 and began selling his product to the general public under the name of "Ryukakusan."

The name "Ryukakusan" came from the names of the ingredients in the original formulation: carina, deer antler, and borneol, known as "ryukotsu," "rokkakuso," and "ryuno" in Japanese.

Late 19th century to mid 20th century (mid Meiji–early Showa period)

In 1893, Tokusaburo Fujii modified Ryukakusan into its final form as a fine powder preparation and established his own store called Fujii Tokusaburo Shoten.

The formulation and dosage form of Ryukakusan have changed very little since then, and the herbal ingredients continue to be the principal agents.

The origin of the dosage form can be found in Chinese medicine, which has thousands of years of tradition.

Towards the end of the Meiji period, Fujii Tokusaburo Shoten was actively engaging in marketing activities, posting eye-catching advertisements on newspapers.

At that time, the more signboards advertising medicines posted by a drug store, the more trustworthy the store was thought to be.

In 1928, Fujii Tokusaburo Shoten was reorganized into Fujii Tokusaburo Store Co., Ltd.

In 1967, the company also launched Ryukakusan Lozenge, the first lozenge released in the Japanese market. This has the same indications as Ryukakusan but was designed to be easier to take, targeted at women and children.

In 1991, Ryukakusan's new head office building was completed.

A Good Design Award was received from the Ministry of International Trade and Industry (currently the Ministry of Economy, Trade and Industry).

The new Chiba Plant, equipped with research and development facilities, was completed in the Tako Industrial Park in Chiba Prefecture.

The company has been tending to the throats of Japanese people for more than 200 years.

In 2013, a regional revitalization partnership agreement was concluded with the town of Misato in Akita Prefecture. Ryukakusan began cultivation of indigenous herbal medicinal plants in Japan. In the same year, President Ryuta Fujii received an award for distinguished service in the health, medical, and welfare fields from the Tokyo metropolitan government.

The Ryukakusan Logo

Ryukakusan was founded by the Fujii family who follows the traditions of Akita domain.

After considering various designs for the company logo, a dragon design was decided upon in 1963.

The logo is comprised of three dragons, one on top of the other, decorated with five dots.

The final logo was designed by Dr. Tomio Ogata, an accomplished scholar of the time and the great-grandson of Koan Ogata, who is often referred to as the father of modern Japanese medicine.

With a deep knowledge of heraldry, Dr. Ogata has designed emblems for not only Ryukakusan but also its affiliates.
