You’d be best to stay in hotels. That way it’s much easier to access hospitals and doctors if needed.

They will usually go out of their way to help you too. I have found booking.com a good place to book hotels. You can also message them to make sure you can book a suitable room.

My suggestion is to hire a wheelchair from where you live. A lot of wheelchairs are very small.

I’m in the process of setting up a business for travellers with a disability. I would be happy to help you. Feel free to PM me.

I love travelling in Japan as people will go out of their way to help you.

Buses are a good way to see an area. A lot of buses now have steps that can be lowered and most have a special ramp for wheelchairs too.

I would recommend using taxis or go on a customised tour where they can take you where they recommend.
