An interesting itinerary @Grand_Al
Kyoto indeed is an over-crowded place, and I too wondered how the large wide-body bus would squeeze into the narrow alleys of this historic town.
Among the almost free or cheaper sights in Osaka are the Tsenkaku Tower,
The golden quadrilateral of Japan travel is considered to be the Tokyo-Kyoto-Osaka-Hiroshima route.
Of this, Hiroshima has a free hop-on-hop-off bus that takes you through all major tourist places like the Atomic Bomb Dome, the Peace Memorial Park, and the Hiroshima Castle.
I strongly suggest you add some Google Maps locations and also add a few photos from your trip in your post.
