Japan is generally very accessible for people with physical disabilities or mobility issues. 'Multi-purpose' toilets are usually located in between the men's and women's restrooms and are spacious and feature many useful features such as handrails, facilities for those with ostomate bags, and full-size changing tables, although there is no universal design. These are very common and can be found in most train stations as well as shopping centres and department stores and public facilities such as museums, theme parks and other main tourist destinations. Lifts and escalators are very common, in fact Japanese building codes require any building over 4 stories to have a lift, however while there are usually no problems in newer or larger public buildings, in older or smaller private buildings the lift space may be extremely small or not entirely step-free. Japan is the originator of tactile paving blocks for people with visual impairments, and they can be found all over Tokyo and in many other cities and towns. Japan uses its own versions of braille and sign language.
Accessible Japan is a website dedicated to collecting together all the information about accessibility in Japan, with general information on accessibility, trains, toilets, hotels and tourist attractions and even a phrasebook with useful Japanese phrases for people with disabilities.
