BEST USE OF JR PASS

Hi there,

I think the most economic way to go about this is to buy a [Keisei Skyliner & Metro] pass for the first 2 days and buy the JR Kanto pass for your last 3 days (it covers the Narita Express too!). This way you will have all your travel covered and you can use the metro pass to visit the Tsukiji Fishmarket and Rainbow Bridge. The schedule for this would be the same as your 2nd plan.

For reference if you want to buy separate tickets:
Karuizawa is about ¥ 5,950 / 69 Minutes by Shinkansen or ¥ 2,710 / 226 Minutes by local train but with a lot of luggage the first option is certainly recommended.

For your Hotel location, I don't think it matters much if you take the Keisei Skyliner & Metro deal as you can travel anywhere in Tokyo without additional cost.

Hope this helps!

Hi Daniel san
Thanks so much for your swift & useful reply.

How about if I also go to 草津溫泉 on day 4 afternoon then back to Tokyo downtown?
Is the JR Kanto 3 day pass can be used ?

Cheers

Hi again,

The JR-Kanto pass can be used to travel to Naganohara-Kusatsuguchi Station and from there you can take a bus to travel to Kusatsu onsen (670 Yen).

Cheers!
