Yasuko was very attentive to requests that may not be on her list and one of those was the Ghibli Museum which is in the suburb of Mitaka a lengthy distance from the centre of Tokyo. Yasuko was able to quickly purchase the tickets for us (which are difficult for foreigners to obtain)after I sent her payment through PayPal. She then whisked us there by train & taxi and returned us to our hotel by bus (when a taxi wasn't available) & train. No fuss no muss. She made all our tours completely stress-free.
