JR pass

I�fll be going to Japan on Oct 4-14, and have a few questions.
Right now my plan is just to venture out in and around Tokyo Metro from 4-11, but I�fll be staying at a family friend in Kawaguchi Saitama.
On the 12th I�fll be going to Kyoto and staying there until the 14th and planning to go straight to Narita from there.
I�fm thinking about getting the 7-Day JR pass, and I�fve been doing some research and actually used the JR pass calculator which gave me a �gclose call�h (30k yen).
I�fm wondering, can I justify that with the train use in Tokyo including the round trip from Kawaguchi?
If so, I�fll probably have to stick to using as much JR trains as possible, but would that be too hassle?
I appreciate all the feedback. This is my first time going to Japan too!

Kawaguchi into Shinjuku is only 220 yen. So I don't think you'll make it up there. And the JR pass only covers local lines and the circle route Yamanote line in Tokyo. You'll be stuck taking often inconvenient routes to use that pass inside Tokyo. Which means, you'll want a Pasmo or Suica prepaid card for the subway anyway. Just use that to get in from Kawaguchi, too.

If you want just a discount on a bullet train trip to Kyoto and back, this can be a good value: https://www.japanican.com/en/tour/detail/PAS1J02031MKC/

If it is �ga close call�h I would go for normal ticket (or maybe one of the other offers) to be able to ride on Nozomi instead of the slower, less frequent Shinkansen.

Thank you for the replies! I don�ft think I�fll be getting them then. I�fll just get that discounted round trip or look into the Nozomi train.
