Discover Otsuka Australia

Otsuka Australia Pharmaceutical Pty Ltd was established in 2014 with the aim of bringing new innovative medicines to Australian patients in need.

Globally, Otsuka is a leading health-related company with a proud history. It was established in 1921 by Busaburo Otsuka in Naruto, Tokushima Prefecture, Japan. The Otsuka Group has steadily expanded and now employs over 42,000 people with products available in more than 80 countries worldwide.

Otsuka has been on a journey of creativity and innovation for more than 90 years. During this time, we have discovered and developed treatments for central nervous system disorders (mental health), cardiovascular and digestive diseases, cancer, respiratory disorders, and dermatological conditions, as well as a range of clinical, nutritional and diagnostic products.

Our global philosophy

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, gastroenterology 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 available to patients in key markets around the world.

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!
