My family hired Yuki for 3.5 days to see Tokyo and Hakone. We are very sophisticated world travelers and have used many guides over the years. Yuki was perhaps the most warm, flexible, and accomadating guide we have had. He is very knowledgable about Japanese history and the sights. He was superb with my two children, both who became very fond of him. It was a great help having him help us quickly navigate the subways and trains. I cannot recommend him highly enough. Thank you Yuki!
