Sightseeing by wheelchair

My brother is in a wheelchair so I was wondering about the logistics of sightseeing in Kyoto. I've heard that trains and buses in Kyoto are wheelchair accessible but would a taxi be easier?

Here's some information on the subject. If you're brother is able to easily move between the wheelchair and the rear seat on the taxi, then it probably is your easiest option.
