Do you wish to book a day trip exploring Tokyo or other cities while you are staying in Japan?
We recommend you book your tour in advance through the website of JTB Sunrise Tours.
They also have an office at the front desk of the Keio Plaza Hotel.
You can also explore Tokyo on your own. The most convenient way to do so is by taking the Yamanote line, which is a train going in a circle around the city, passing most of Tokyo's major sights. Shinjuku Station is just 10 minutes walking distance from the Keio Plaza Hotel.
