Our Global Philosophy
Otsuka - people creating new products for better health worldwide
To turn our corporate philosophy of ‘Otsuka–people creating new products for better health worldwide’ into reality requires passion, leadership, dedication, diversity and perseverance. 

Our Values

‘Jissho-Shugi’ (proof through execution) and ‘Sozosei’ (creativity) are key values at Otsuka. In other words, we encourage our people to push themselves to consistently do extraordinary things that lead to them being given greater responsibility. We have always believed that human ingenuity triumphs over the use of computers when it comes to being creative and having those eureka moments when thinking of products nobody else has thought of.

Unconventional Approach

Challenging the routine and the ordinary is a philosophy that drives us to do better. Otsuka people think unconventionally in areas where there is an unmet need, researching and marketing innovative products and medical devices in our key therapy areas of mental health, endocrinology, nephrology and oncology.

Thinking Differently

By striving to face challenges, by thinking differently, and by taking the road less travelled, extraordinary things can happen. It is this willingness to challenge established ways of thinking and avoid generic approaches that makes Otsuka special.


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 an antipsychotic drug that is now available throughout the world. Many would have given up, but thanks to the remarkable tenacity of our people, it is now one of the world’s top-selling pharmaceuticals.

Big Venture Company

We believe in a big venture approach to treat major diseases, where unconventional thinking will bring success in delivering new and better healthcare products that really make a difference to people’s lives. To make this happen, our employees are encouraged to break the boundaries of conventional wisdom, to cross into the unknown and to think big…and then even bigger!

Super People, not Super Computers


“When a method was developed for modifying the structure of compounds, and thereby developing pharmaceutical products, using a computer, I thought about closing down the company completely. If a computer can do the work without human contribution, then it seemed likely that small companies unable to purchase super computers would be put out of business. The nature of research belongs to people. The large multinational corporations that are capable of buying super computers are struggling to develop new drugs; they are actually buying compounds and developed products from smaller venture companies. Someone told me that ‘Otsuka Pharmaceutical is a large venture company’. People make the company run; people do the thinking. Otherwise, we’d be in trouble.”

 The late Mr Akihiko Otsuka, Otsuka’s former Chairman and Representative Director.


Unconventional ThinkingThree permanent symbols of creativity can be seen in the Human Development Institute in Tokushima, Otsuka Pharmaceutical’s birthplace in Japan. They highlight how Otsuka likes to think differently and avoid stereotypes.

A sculpture has been created from two large cedar tree trunks, where a straight trunk is impossibly balanced (held in place by two small wedges) on top of a standing bent trunk. The sculpture is a reminder of the need to think differently and how creativity can overcome seemingly impossible problems.

The stone garden features large stones, which appear to miraculously float on water. The garden was created to capture people’s interest, enrich the mind and cultivate the ability to think. The stones represent the power that a company can harness by changing conventional ideas and approaches.

An ordinary tomato plant produces fewer than 60 tomatoes each year, but if you remove the soil and use hydroponics instead, up to 10,000 tomatoes can be produced, as seen in the Tomato Hall in Otsuka’s Human Resource Development Institute. The same concept applies at Otsuka – by freeing our minds to explore, we can unlock our true potential.
