The World Blind Union is a coalition of organizations, often for the blind, and we are in 190 countries in six regions. We get to see the best of the best and the worst of the worst.
I would say Japan.... The Emperor of Japan, who has a grandson who is blind, has decreed that the entire country will be accessible. You find Braille everywhere, and large print, colour contrast and tactile indicators. There is nowhere I went in Japan that wasn't accessible. When it comes to the physical environment, Japan is the place to look.
I would say that there's a lot of work being done right now in digital accessibility. The problem with that, of course, is that digital is an international space, and it's kind of this concept rather than a physical space. It's very difficult to do that. I would say that there's a lot of work being done in that area that we could be looking towards in finding ways to create better technology access.
