Is it worth it to buy 7 day pass

Hi there,

If you plan to make this journey in a week then it is certainly worth getting a 7 Day JR Pass.

Here is a little oversight of prices without the pass.
Narita Airport --> Kichijoji ¥ 3,480
Kichijoji --> Shinjuku ¥ 210
Tokyo --> Kyoto ¥ 13,420
Kyoto --> Tokyo ¥ 13,420
Tokyo Kamakura (return) ¥ 1,780

This adds up to ¥32,310 the 7 day JR pass is ¥28,300 saving you ¥ 4,010.

Hope this helps!
