Since its establishment in 2011 as a clinical trial clinic, this clinic has contributed to the birth of new medicines through clinical trials, and in 2021 we began outpatient clinic in order to contribute to the better health of you and your local community.
In Japan, the average life expectancy is over 80 years for both men and women, making it one of the countries with the longest life expectancy in the world. But the ‘healthy life expectancy’, the period during which people can live in good health, continues to be shorter than that. Extending healthy life expectancy leads to wellbeing. To achieve this, it is important to address health concerns as soon as possible. If you have any concerns, or even if you are not aware of any symptoms, please feel free to visit us for a check-up.
Our general internal medicine specialists and nephrologists treat a wide range of common illnesses such as the common cold, hay fever, tiredness and stomach problems, as well as lifestyle-related diseases such as hypertension, diabetes, hyperlipidaemia and obesity and so on. We also offer specialist outpatient clinics for chronic pain (headache, neuralgia, back pain), neuromuscular diseases and memory loss (dementia), so please feel free to consult us!
The clinic is located in Okubo, Shinjuku-ku, a cosmopolitan area with excellent accessibility from many directions, and we support with multilingual (English, Chinese and French), which also welcomes inbound patients.
