Yasuko was great. She is knowledgeable and personable.The tour followed the basic itinerary which Yasuko tailored to our preferences once she saw how we toured. We like to walk and move quickly, and with Yasuko's help we had a great 4 hour tour which made us feel like we actually covered most of Tokyo including local shops,fish market,shrine,temple,riding the subway,the palace grounds,local snacks,chatting with local school kids...... Thank you!
