You might want to try Tours By Locals (One of my friend is a guide for them in Hiroshima). You can filter the search results by “wheelchair accessible” and then can communicate with the guide about your needs.
From what I understand they can be much more flexible than other guides and offer personalized tours in most cases. So you could just tell them what you need and you can work out the details from there.

Click “More” at the top of the page and choose “Wheelchair accessible” as a filter.
