I'm going to Japan for the 5th time in 2 months as a wheelchair user. I want to share lots of tips and recommendations for disabled folks and wheelchair users, so that your first trip will be great. Japan is wheelchair accessible enough to explore and have fun. Yes, there are barriers, but it's doable. Wheelchair users deal with barriers every day, and it's no different in Japan. Below are my tips from a previous post that I regularly update.

I also uploaded a video taking the JR Yamanote Line from Shinjuku to Ikebukuro stations, so that you have an idea of how accessible it can be: https://youtu.be/-HKaEwDnJVo
