Many martial art athletes go to Miwa Chiryoin(treatment) near
Akebonobashi station (Shinjuku line subway).
1 minutes walk from A2 exit, through the Akebonobashi shopping street,
right side, 4 th floor of Seven Eleven building, in front of Chinese
restaurant.
Miwa Chiryoin:tel:03-3358-0752 call them in Japanese!

I myself have tried many different places however I prefer having
the treatment in Miwa because they are a kind of clinic that heals
the body not only giving relaxization.
They hire only the professionals who have licence that can be given
by the authority to the person who graduated alternative medical institute
where give education for a couple of years about the knowledge of
human body just like a medical collage.
In the unauthorized private massage parlors the staffs are sometimes
unprofessional or part time workers that is why it is dangerous to let them
touch the body without knowing the specialized knowledge about the
body structure/muscle/organ/disease, etc.
national health insurance of Japan visa holders paying 30%
travel health insurance traveler,
short term stayer
paying 100% then
refund 70% with receipt
Note:
It is better to take somebody who speaks Japanese as they don't speak English.
