About Us

History of Otsuka

Otsuka Group started in 1921. Busaburo Otsuka established a chemical compound factory in Naruto, Tokushima Prefecture, now Otsuka Pharmaceutical Factory Inc. In 1946, this small-scale manufacturer of chemical raw materials began producing and selling intravenous solutions.

In 1950, the organic chemicals division split from Otsuka Pharmaceutical Factory to form Otsuka Chemical and Medical Products, Inc., now called Otsuka Chemical.

This was followed by the establishment of Taiho Pharmaceutical in 1963 and Otsuka Pharmaceutical in 1964. These new entities were steps in the evolution of a manufacturer specializing in R&D.

Giant Tomato Tree

“In order to change preconception, we planted the Giant Tomato Tree.”

Normally a tomato plant produces only 50 to 60 tomatoes,
but if you alter the way you cultivate it,
it has the potential to produce 10,000. Likewise,
if people think a little differently,
they could unlock their enormous potential.

Bent Giant Cedar

Conveys a constant message about breaking down
stereotypes and changing our thinking.
It requires unconventional approaches
to solving problem for our customers and communities.

Floating Stones

The gently curved stone represent Otsuka Pharmaceutical’s

Spirit it’s love of humanity
and its wish for people’s well being.

Thai Otsuka History

Before 1965, Thailand had, product and use of Basic Intravenous Solutions in glass bottles and imported from Europe. Otsuka (Pharmaceutical company in Japan) foresaw the opportunity that the Thai people could use more modern and safer Basic Intravenous Solutions and, therefore, collaborated with Chor. Charoen Bhaesaj managed by Khun Charoen Suntayodom, in importing Basic Intravenous Solutions in plastic bottles with the closed system and subsequently it was well popular among the Thai people and could not meet the market demands. Khun Charoen took the milestone decision to produce these products locally instead of importing from Japan. So he negotiated with the executives of Otsuka Pharmaceutical Co., Ltd., Japan at that time to invest and establish a company and Basic Intravenous Solution factory in Thailand under the efficient technology of Otsuka Pharmaceutical Co., Ltd., Japan.

Thai Otsuka Pharmaceutical Co., Ltd. was officially established on December 7, 1973, making it the first joint venture outside Japan of Otsuka Group.

For over 40 years until today, Thai Otsuka Pharmaceutical Co., Ltd, has still adhered to the first concept when it was established for the better health of Thai people. We promise to innovate, develop and improve in order to obtain the quality products and enhance the better quality of life for Thai people forever.


Thai Otsuka Pharmaceutical Co., Ltd. was established with a registered capital of 10 million Baht.


Construction of Basic Intravenous Solutions factory was completed and it was ready to produce Basic Intravenous Solution in plastic bottles with closed system.


Pure amino acid solution which is Parenteral Nutritions was initially produced for the first time in Thailand.


Drugs imported from Otsuka Pharmaceutical Co., Ltd. Japan which had been invented, researched and developed to meet the needs of patient were initially sold.


Production of Medical Foods was established and initially run for the first time in Thailand.


Products of Thai Otsuka Pharmaceutical Co., Ltd., both Basic Intravenous Solutions and Medical Foods, have been accepted in many countries.


The New Product Development Department was set up to develop new formulae of Medical Foods to meet Thai patients and consumers’ needs. Moreover, a new plant was built to manufacture Basic Intravenous Products with PIC/S GMP standard for export, also exported to Japan where the quality of imported products is very strict.


Mr. Shinsuke Yuasa

Inspired by the Otsuka Group’s corporate philosophy “Otsuka-people creating new products for better health worldwide” and our motto “Your Health is Our Life”, we Thai Otsuka Pharmaceutical strongly strive to seek for unmet needs of both patients and healthcare professionals in Thailand and continuously introduce and/or develop innovative and customized products to respond to their requirements. By the cultivation based on Otsuka’s DNA of “Ryukan-godo” (Discovery through hard work and practice), “Jissho” (=Self-actualization) and “Sozosei” (=Creativity), what we see, sense, think and act is out of the box; in other words, we’re passionate to research, manufacture then deliver the best outcome with innovation and uniqueness.


In Thailand, medical food is one of our significant efforts for the commitment. With a good collaboration of highly recognized Thai doctors, a series of nutrition products for specific diseases have been successfully released into the Thai market over recent decades. We are proud that some of them are currently officially registered in the Thai Government’s Innovation List as well.


Another key business driver for us is people. People is the most valued resources of our organization. Therefore, we aim to create a happy and family-like environment where our employees love to come to work, pay respect and give support to one another as our theme of One Team One Goal. Furthermore, they’re also given opportunities to develop new skills, grow their knowledge, and learn through experiential learning; so they can promote natural learning to unleash their potential which they may serve better health of people with a great contribution in the future.
