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.
Hakone is very popular spot. It is 1.5 hours away from Tokyo by train and bus. Many travelers want to visit there as day trip from Tokyo. Hakone is located on the way to Osaka, Kyoto and Nagoya from Tokyo. You may add Hakone between Tokyo and Osaka, Kyoto, Nagoya.
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.
I actually do not recommend to visit Lake Kawaguchi and Hakone in one day. There are many places to see. One way is not obviously enough to visit these places. But some of you have very tight schedule. You cannot choose which one you visit. You may be wondering if you have to visit one of Lake Kawaguchi or Hakone. This sample itinerary may be suitable for you. It is very very tight schedule and you have to give up many places. But you can visit most of highlights at both side of Fuji, Hakone and Lake Kawaguchi. You may be okay to see these places in Hakone and Lake Kawaguchi.
Some of you are wondering if you should use JR pass or not for one way trip from Tokyo to Osaka via Hakone and Kyoto. Actually JR pass does not meet this trip. The price of 7 days JR pass is 29100 yen. One way base fare from Tokyo to Kyoto or Shin-Osaka plus Shinkansen surcharge is around 14000 yen. As long as you have one way trip from Tokyo to Kyoto or Osaka, JR pass is way more expensive than single fare. Even if you use JR pass when you stay in Tokyo, Kyoto and Osaka, it is not realistic to spend another 15000 yen. Base fare in these cities is 200 to 500 yen.
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.
