[Accessible Japan]

Hi again @Julie

How about this taxi company: http://www.ace-fukushi-taxi.com/index.html
They are located in Kita and have an email inquiry form, so they should be easy to contact.  They charge depending on the type of trip (ie either by distance, or time etc), but you can rent out a block of time at 2,000 / 30-minutes.

This one is also relatively close: http://www.kumataku.co/index.html

There are a bunch more in Kumamoto City itself and they are likely willing to go to Kita as it is only about 30-40 minutes from Kumamoto city.

You may also be able to rent an accessible vehicle as well: http://www.grace-ohhashi.com/pickup/index/2/

Hope this helps!
