Our Unique Culture

Otsuka is an extraordinary company where people do extraordinary things. We are a magnet for top talent. Those who join the Otsuka family know that they will be highly valued and encouraged to fulfil their potential. That’s because we adhere to a number of key values that make us a unique and attractive proposition as we strive to be a great place to work in pharma.

Jissho and Sozosei

‘Jissho’ (Self-actualization) and ‘Sozosei’ (creativity), which pervade everything we do, reflect our Japanese heritage. In other words, we encourage our people to push themselves to consistently do remarkable things that lead to achievement, completion and the discovery of truth. An example of Jissho is how regional account managers from our various therapeutic areas are selected to serve on the Field Advisory Board (FAB) teams.  These teams are the voice of the entire field sales force, providing insight and guidance on improving procedures and making recommendations to implement innovative technology solutions for the benefit of the entire company.  The FAB team members are selected as a result of their performance (self-actualization),  understanding of Otsuka’s culture and their ability to make contributions outside of their normal job responsibilities.

Thinking Differently

We believe in thinking differently and in challenging the norm, which drives us to do better than before. By encouraging our people to think unconventionally in medical areas where there are unmet needs, we have delivered innovative products in our key therapeutic areas of interest. Otsuka has always believed that human ingenuity triumphs over the use of computers when it comes to being creative and to having those “Eureka!” moments when thinking of products nobody else has thought of. An example of our unconventional thinking is Otsuka’s foray into digital medicine where we have developed, in  collaboration with Proteus Digital Health, Inc., the world’s first drug/device combination in a tablet, which was approved by the FDA in November 2017. The digital medicine system, ABILIFY MYCITE® (aripiprazole tablets with sensor), provides data on ingestion adherence and other physiological parameters in patients receiving treatment for mental health problems. It is this willingness to challenge established ways of thinking and avoid standard approaches that makes Otsuka-people special. It is why we believe in our maxim of 'only what Otsuka can do'.


Through pharmaceutical research, we continue to identify new treatment advances of high clinical value, avoiding the development of ‘me-too’ products. As a company, we don’t follow the crowd; we don’t just rely on computers for answers – we persevere, trying new avenues until we reach our goals. For example, it took 25 years to research and develop ABILIFY® (aripiprazole), an atypical antipsychotic drug that is now available throughout the world. Many would have given up, but thanks to the remarkable tenacity of our people, it was one of the world’s top-selling pharmaceuticals and enabled us to continue to invest in our research and development efforts.


We value diversity of thought which means that we form alliances and collaborate with other companies when we see there is an advantage for both parties.  
As well as diversity of thought, we strongly believe in cultural diversity among our workforce. Otsuka-people come from all parts of the world and various professions. What matters most to us is that our people believe in the Otsuka philosophies and values, and have the creative and innovative qualities that we cherish. If you have what it takes to succeed at Otsuka, we provide the environment and the encouragement to do so.

"People make the company run; people do the thinking. Otherwise, we’d be in trouble."
Akihiko OtsukaThe late chairman of Otsuka Holdings


In Tokushima, Otsuka Pharmaceutical's birthplace in Japan, three symbols illustrate how Otsuka likes to think differently and avoid stereotypes.
  • An extraordinary curved cedar tree that has another cedar tree lying on top of it in a way that does not look possible, yet the whole structure maintains a perfect balance. The aim of this structure is to convey a message about breaking down stereotypes and to change perceptions of what is and isn’t possible.
  • A stone garden where large, heavy stones appear to float on water. The paradox of this mesmerizing garden is intended to stimulate and encourage people to think in a different way and come up with new ideas.
  • The Tomato Hall where visitors are faced with a forest of thousands of plump, red tomatoes that have grown from just a few tomato plants. These are ordinary plants that would only produce some 50 to 60 tomatoes if planted in the ground. Yet by using hydroponic cultivation the potential of each plant is unlocked, allowing it to produce an astonishing 10,000 tomatoes.
