The school was called Tekijuku, where distinction of status was unknown and competition abounded.
Much of Ogata's life was devoted to Rangaku, which was clearly displayed in the vision he had for Tekijuku.
Dr . Kaoru Shima ( 1897 1977 ) graduated from the Osaka medical school, the present Osaka University medical department, which originated in the " Tekijuku " school.
The original Dainippon Pharmaceuticals ( Dainippon Seiyaku ) was established in 1885 by Nagayo Sensai, a graduate of Tekijuku the first private medical school in Japan established by Ogata KMan.
Najita marks the academy's decline with reference to the rise of the Tekijuku as a nearby foreign language school of medicine and other ( western ) sciences which gained in popularity since its inception in 1838.
In 1838, Ogata returned to Osaka to establish his medical practice, and in the same year established the Tekijuku, an academy of rangaku studies, where he taught medicine, natural history, chemistry and physics for the next 24 years.
The spirit of the university's humanity sciences is believed to be intimately rooted in " Kaitokudo ", whereas that of the natural and applied sciences, including medicine, is widely believed to be based on " Tekijuku ".
