Welcome to OSC!


Thank you for visiting our website. My name is Kenichi Oumi, a board-certified Doctor of Chiropractic (DC) practicing in Tachikawa, Tokyo, Japan.


If you suffer from not only neck and back pain but also various kinds of issues/injuries such as ankle sprain and knee/shoulder pain, and also you seek someone who actually can treat the cause not just the symptom to make your life better and more active, this is a good place to start.


OSC provides combined treatments and therapy including chiropractic adjustment, soft tissue treatments (muscular release/IASTM/taping), and a home exercise program to improve your condition and performance.


We love to support active populations from weekend warriors to professional athletes.


The office is located at Tachikawa, the city on the west side of Tokyo. The closest station is Tachikawa Station (JR Chuo line, Ome line, Namboku line, and Tama monorail) and you can take a walk from the station to the office (refer to the map below).


Appointment necessary, therefore please contact us before your visit. It's difficult for us to accept walk-in clients. 


If you are not familiar with chiropractic care, please take a look following videos for a better understanding of chiropractic.

Who sees a chiropractor?


How often should you see a chiropractor?


We see people from all over the world.

Most of people from other countries have a problem to see a local health care provider in Japan because it's sometimes hard for them to explain their conditions in Japanese.


That is why we see people from all over the world such as someone who works here, international students and tourists.


We are looking forward to seeing you from all over the world!
