Worth getting pass

Hi there!

I do think that a JR Pass would be the best option for this route. With a little bit if planning you could cover the following routes and make great savings over normal ticket prices.

Narita Airport - ¥ 2,740
Tokyo - Kyoto - ¥ 13,020
Kyoto - Nara (return) - ¥ 1,380
Tokyo - Himeji ¥ 4,930 (by Shinkansen)
Himeji - Odawara ¥ 13,760
Tokyo - Nikko (return). ¥ 10,460

For a total of ¥ 46,290 the 7 day JR Pass is ¥ 28,300 so you would save at least ¥ 17,990. What I would do is visit Nikko on Fri 18th, this way you could use the JR Pass to travel there too, which would help to maximize your savings.

Hope this helps!
