Place to stay for disabled

Hi!
about 3 years ago i went to japan for almost 2 weeks, had a wonderful experience and planning to visit again. My question is, is there any convenient place for disabled to stay in japan? a place to stay that has the easy access to use toilet and shower. Thank you

These webpages sound like good places to start:

http://wheelchairtraveling.com/wheelchair-travel-guide-to-japan-for-wh...

I am sure if you also spend 5 min with google youfll find many more.

Enjoy your trip to Japan!

When searching for a room, the term for gaccessible roomh can vary by hotels.
Some examples:
Barrier-Free Room
Universal Room
UD (Universal Design) Room
Handicap Room
Accessible Room
Heartful Room (I think only Toyoko Inn uses this term)
Wheelchair Compatible Room
