Hello, I suggest you get in touch with @ohayotravel and he can maybe help you with the rental, but also introduce you to Abilities – I believe you can visit their showroom in Tokyo.

Unfortunately I think they are the only authorized repair shop for Permobil… Instead of changing your flight and being stuck in your hotel room, maybe it is best to put it in manual mode and push it to a wheelchair taxi? Then you can have your local shop repair it.

Great info, thanks for sharing!

There are a few other travel agents dealing with accessible travel like @ohayotravel and @wanping
