Accessible Japan is a highly useful, much-needed English-language site specializing in sightseeing, lodging, and other tourism-related information for travelers who require wheelchair accessibility. I stumbled across this site by pure chance, and because many travelers require this kind of information, I decided to post the link here (it’s also been added to my links section on the right). Not only does it provide information on locations of ramps, availability of rental wheelchairs and accessible toilets, information on inclines and other landscape characteristics, and other such information, it also has a lot of good general recommendations and advice for tourists.
If accessibility is an obstacle that has prevented you from making the journey to Japan, I suggest you check out this site. Be sure to take a look at their extensive links sections, as well.
Accessible Japan is put up by TESCO Premium Search Co., Ltd., a company that aims to provide job opportunities for people with disabilities.
