12th April: Hakone to lake kawaguchi
13th April: lake kawaguchi to Shinjuku
14th April: Enoshima island and Kamakura day trip
15 April: Shinjuku to Matsumoto
16th April: alpine route and stay overnight at Toyama
17th - 20th April: Tokyo

Please kindly advise if the passes are recommend for my itinerary.

Thanks and regards,
Siew Chee
