Really enjoyed this trip. We went on our anniversary with our young daughter. The staff provided great service (all you can drink: alcoholic and non-alcoholic). The tour is mainly conducted in Japanese so be aware, but by the end we can honestly say that we made 30 new friends (of which very few spoke English :). They were very generous as it was our anniversary and recognized us. Our daughter loved it. Just be aware the trip (at least at the time of this review) was non-refundable. But overall a terrific experience. :)
The start time provided by Viator (5:30pm) and by vendor (6pm) were incorrect. Cruise boarded at 6:30pm. The boat was nice; seating on the floor (take shoes off) so difficult to see outside. We could open the windows; and we were able to onto the roof on several occasions for photos.
Meal was superb. We got a listing of food items which was a nice touch. Everything was tasty. The tempura was especially nice since every piece was served separately so pieces were HOT and crispy. The service was spot on. I didn't understand any of the announcements since I don't understand Japanese but that was fine with me. If we were being requested to do something, one of the staff came by and explained with gestures, etc. I would recommend this to all my friends.
