The walking tour was good. The tour guide was polite and knowlegeable, and he mingled well with everyone in the group. I would say no one felt left out. My only gripe about the tour was its cost. It is on the high side. I took a tour to Kyoto and Nara, also with Viator, the following day, which cost slightly more than this tour, and that one took us to many more places and, sights and sounds. Price-wise, the two tours are not on par with each other, the Osaka tour is very much on the high side, with only two attractions (Osaka Castle and River Cruise) while Kyoto/Nara tour was a full day one packed with numerous venues, with coach transportation from venue to venue, and a buffet lunch thrown in.
