Wonderful experience! The diamond tour guide was amazing. He was funny, entertaining and really nice. We had a good tour thanks to him and are very grateful for his performance. The views were unbelievable. They are something that you dont see often in your lifetime, if not ever! Definitely have a good camera to take lots of photos and immortalise the experience. I would also recommend spending some time just to take in the views without looking through your phone as it cannot capture the grand scale of it properly. We loved the tour as first timers in tokyo and would recommend it to anyone going to tokyo!
