Eisai's Founder, Toyoji Naito

Here we present some of the life story and philosophy of Toyoji Naito,a man who not only created Eisai, but also helped to usher in a new era in Japanese homegrown pharmaceutical innovation and industry.

1) Toyoji resolves to establish himself through self-education

Eisai's founder, Toyoji Naito, was born on August 15, 1889 in Ito, a poor village in the Nyu region of Fukui prefecture, central Japan. He was the third son and sixth child in a family of loggers and farmers. Toyoji's mother Fuji passed away when he was seven years old. With his mother gone, young Toyoji would wake up at five in the morning to make breakfast and pack lunches for his father and siblings before heading off to school. As Ito was built in a mountain gorge, commuting to school required traveling over six kilometers each day along mountain paths. When he returned home in the evenings, he would prepare dinner for his family. Such was Toyoji's daily routine until the sixth grade, when he decided to graduate from elementary school two years early (in those days elementary schools in Japan followed an eight-year curriculum) and skip ahead to Takefu Middle School. In his biography years later, Toyoji reflects back on this period:

“Although students in Japan at the time normally progressed to middle school after completing their full eight years of elementary education, I was fortunate enough to pass the middle school entrance exam after graduating sixth grade. Out of the blue, the neighbors in my village began to treat me as if I were some sort of child prodigy... Frankly, I was very much fed up with elementary school by then; the lessons tended to be too slow-paced.”

In his second year of middle school too, however, Toyoji came to a different decision. Rather than spending the time and money on obtaining academic credentials by graduating middle school, high school and, later, college, Toyoji resolved to drop out of middle school there and then and establish himself in the world through independent study via correspondence courses and practical experience. Furthermore, he also began to learn English from a priest brother-in-law who had studied at the National English Association in Tokyo, a move by Toyoji that would later provide him with a competitive edge early on his career.

In 1905, Toyoji left Ito at the age of 15 and moved west to Osaka. Although he first began as an apprentice at a mother-of-pearl button factory, the English skills he had built up led him to a new apprenticeship at Winkel Shokai, a German-owned trading company that was looking to take on a Japanese national proficient in English. This position required him to move to nearby Kobe, a port city in Hyogo prefecture. Toyoji knew that learning foreign languages would likely continue to prove useful in his career and began to study German and Chinese at night school after work in addition to furthering his English. With so many foreigners living and working in Kobe, he was able to make immediate use of his language skills. Toyoji was also required to interpret as part of his responsibilities and learn about the export and import business through hands-on experience rather than being confined to merely burying his head in books.

Once Toyoji turned 20 years old, however, he took the military enlistment screening test as was customary at the time and joined the Japanese Imperial Guard. As fate would have it, there he was found to be inherently unable to look at things through just one eye. As a soldier unable to close one eye during shooting practice, nor fire a gun, Toyoji's only option was to become a military medic. It was through his two-year military service that Toyoji first learned about medical treatment and medicines, which ultimately served as a major factor in his entering the pharmaceutical trade upon his return to Kobe.

Toyoji preferred a smart style, wearing suits and ties at a time when a traditional Japanese sash and apron were the norm.

3) Toyoji's pharmaceutical knowledge increases through dedicated study during his time working at a British-run pharmacy company

After completing his military service in 1911, Toyoji returned to Kobe, which he had by now come to regard as a second home, to work at a British-owned pharmaceutical trading company called Thompson Trading Co., Ltd. At the time, Thompson Trading served as the exclusive Japan distributor for pharmaceutical companies from all across Europe, and the company happened to be looking to hire an English-speaking Japanese person who possessed some knowledge of medicines. Toyoji soon realized, however, that what he had learned during his time as a military medic was far less useful in real life. Toyoji immediately began studying profusely by reading books about medicine in their original language, looking up almost every single term as he went. As a result of his hard work, Toyoji rose steadily to become a top-notch sales representative, traveling from western Japan to as far as Tokyo in Japan's east to introduce new products to doctors and pharmacists. Thanks to his efforts, sales at Thompson Trading grew with each passing year, and the company did so well that they were able to employ several new staff three years later. The Eisai tradition of placing strong emphasis on thorough product information distribution through activities such as employee sales pitch contests and other initiatives to this day are indeed the product of Toyoji's experiences at Thompson Trading.
