The tour guide, a female whose name I don't remember, was great. I don't speak Japanase so she explained how the tour worked while on the bus, because her English is limited. The destinations have signs in English so I got by on my own just fine. This is not a fully guided tour, meaning; the tour guide doesn't lead you throughout the locations, every one sets off on their own. She said the most important information to me in English before getting off the bus, so I knew when and where to be back. The biggest part of this tour is the aquarium. I found the 3 hours were plenty of time to see the highlights of the aquarium and have lunch. The food at the aquarium isn't great, before the aquarium we stopped by a beach that had shops and I wish I had eaten there instead because it had better options, so keep that in mind. The bus was comfortable and had wifi. Later in the tour there were places that I wasn't interested in, it was fine to stay in the bus, as others guests besides myself did.
