[Accessible Japan]

Hello, thanks for the question!

We can definitely look for options. (^_^)

First though, two questions:

1) Just to confirm, we are talking about Kita-ku just north of Kumamoto, correct? Do you know the nearest train station?

2) What type of wheelchair does your friend use?
In Japan there are various sizes of wheelchair vans.  The large ones that can handle power wheelchairs are rarer, but ones that can take a manual wheelchair are much more common.

Looking forward to hearing from you!
