My friend and I are planning to spend 4 days in Tokyo, 2 days in Fuji (to climb Mount Fuji), 2 days in Kyoto and 2 days in Osaka in that order, in August. The days spent in each place after leaving Tokyo may change but it will stay at 6 days in total.
Our flight lands at Tokyo Airport but we leave at Osaka airport therefore a return journey to Tokyo is not needed.
Would it be worth it to get the 7 day JR Pass if we activate it on the day we leave Tokyo, even though we are not planning a return journey?
And if the pass is not needed, would be just have to buy the one-way tickets there or would we have to reserve seating somewhere? Or perhaps is there another method of travel (or train company) which is the better option?
Thanks in advance,
