Konnichiwa!
My girlfriend are planning a two week, low-budget backpacking trip to Japan (Apr 25 - May 9) and would appreciate your thoughts and advice regarding our itinerary. We current intend to spend our first week traveling to several Japanese cities (Kyoto, Hiroshima, and Kanazawa) using a 7-Day JR Pass, and spend our second week getting to know Tokyo. Our idea is to stay in Tokyo during "Golden Week" and avoid traveling across Japan those days as to avoid higher prices, crowds, and delays.
Below you will find our preliminary itinerary - we would like to finalize it as soon as possible in order to book our accommodations before they get too expensive. We would also like to know what train(s) we need to take using our JR Pass in order to complete our journey, and whether we need to book them in advance given the high tourist season. Many thanks in advance for your support!
