I will be going to Japan for 2 weeks and wondering about the most economical use of the JR pass(es). I anticipate the following travel
Day 2: To/From Narita to downtown Tokyo (staying in Narita, fly to Takamatsu on day 3).
Day 3: possible day trip from Takamatsu to Kotohira
Day 4: Takamatsu to Iwo-Saijo round trip
Day 5: Train from Takamatsu to Oboke
Day 7 Train from Oboke to Kyoto
Day 12 Train Kyoto to Tokyo
Day 14: Train Tokyo to Narita.
I am wondering if the best option is to
1)buy a 5-day Shikoku pass, and just buy normal tickets for Oboke-Kyoto and Kyoto-Tokyo (as well as travel to/from Narita)
2) buy Shikoku 5 day pass + 7 day rail pass (to cover Oboke-Kyoto and Kyoto-Tokyo and last trip to Narita)
3) Buy a 14 day pass to cover all travel for the whole 2 weeks.
Is it right that the first option is the most economical since the Shikoku pass is such a good price, and I believe Oboke-Kyoto and Kyoto-Tokyo and Tokyo-Narita together still don't add up to the price of 7 day pass?
Thank you very much for your help.
