Dai was really great. My husband and I had one day in Tokyo. We could not have done half the things we did without Dai. He had early access to the fishmarket we alone could not have gotten, and we covered everything I wanted to see and more. He had great and informative commentary and history. He was prompt, efficient, and patient. I will be recommending him to everyone heading that way. As I understand, he does other places besides Tokyo too, so when we head back that way, we will check in with him first.
