We highly recommend our tour guide in Tokyo, Akio Horisaki. We had a great time despite many hours of walking. He is already 80 years old but he is agile. Such an inspiration for us to strive to reach such age healthy and happy. He said that the secret to a long and healthy life is to not worry and always be positive. Thank you very much, Akio Horisaki. We admire your strength, patience and dedication. We hope to see you again soon.
