But this itinerary covers both Lake Kawaguchi and Hakone areas in one day. It is very tight and many places are not covered. If you can spend two days, you can enjoy Fuji and Hakone areas one day each. You can visit many more places easily.
In this sample itinerary, I tried to put most of popular spots in these areas. And also this plan includes Fuji Shibazakura festival which is most popular event in spring. You can do this trip from Tokyo to Tokyo. You also can squeeze this trip between Tokyo and Osaka. You can drop by this area on the way to Osaka or Kyoto from Tokyo or versa.
7 days JR Pass price is almost same as round trip fare between Tokyo and Osaka by Shinkansen. That means if you have one way trip from Tokyo to Osaka or reverse, JR Pass is not worthwhile using. However if you add some trips when you stay in Osaka and Tokyo, you may use JR pass 7 days.
Most of travellers who stay in Tokyo think about visiting Hakone (箱根). It is only a few hours away from Tokyo. It is well known as one of the most popular hot springs resort in Japan. And also it is very close to the highest mountain in Japan, Mt. Fuji. But Hakone is not connected with Tokyo by Japan Railway. That means Japan Rail Pass cover limited part of your trip to Hakone. Odakyu Electric Railway (小田急電鉄) that is one of the major private railway companies in Tokyo and Highway bus are more convenient way to get there. Though Japan Rail Pass cover limited part of travel, some of you still think about using Japan Rail Pass as much as you can and try to minimize the extra cost.
