I would recommend Yuko san to anyone who is looking to find a guide to explore Tokyo and surrounding. She is responsive and flexible throughout the process, she even help me fins some items I needed in Tokyo and recommend a very good restaurant for us to enjoy. She is also knowledgeable and understand the history of Tokyo and able to explain it to us clearly. Her rates are very reasonable compare to the others in the web. Perfect choice and will definitely use her services again in Tokyo.
