Well, the cruise in itself was very beautiful: the view was amazing, especially the planes about to land right over the cruise boat looks magnificient live but we have experienced some issues that are important to mention.
First of all, OBS! VEGETERIANS - don't expect to get a great variety of dishes on this cruise. Though it stands that the vegeterian option is available and must be ordered in advance, we have still been quite disappointed. On our tour the only available vegeterian food was bread, some cooked vegetables, plain soba noodles with some unknown sauce on the side ingredients were written in Japanese so we didn't risk to try it, even with Google Translate and some desserts. We don't know if it's Viator that hasn't provided the company with our reservation of vegeterian meal or the company itself that has made the decision to include very few vegeterian options but just be aware of this probability when you book this tour.
And secondly, all the staff spoke in Japanese only so we had no idea what the safety on board rules were, for example. It was also impossible to find out what kind of dishes were available at the buffet, even when we asked the personnel.
Apart from this, it was a cozy tour and you should definitely try to go up to the top deck and enjoy the view there.
Fantastic experience! The ship was beautiful. We were seated at a table next to the window. The dining room was not overly crowded and the food was delicious. There was ample outdoor deck room to take in the views of the bay. The length of the trip and route around the bay was perfect. The only recommendation is to make the instructions on the voucher clearer. The voucher said We will meet you at the Hinode Ferry Symphony Terminal., which gave us the impression we should be looking for a tour guide. When in actuality we simply needed to go to the check-in counter and obtain our boarding pass. We still boarded on time it was just a bit confusing beforehand.
