2 or 3 week pass?

Hi there,

Nice trip! You will be just in time for the Sakura season!
I must say that this question is hard to answer especially since you don't have a final itinerary yet.
In the end it comes down to flexibility versus budget. The difference between the 14-day and 21-day pass is 12,600 Yen, basically if you can do this amount of travel in the extra days it will be worth it!

I don't think that this would be very hard if you plan on going all the way up to Hirosaki, for instance a one way trip from there to Tokyo is ¥ 17,490, you would also be able to use the JR-Pass on the way back to the Airport saving around an other 3,000Yen compared to normal ticket prices.

If you wish to budget your trip, a 14-day pass may be this best option, I think the best way to use it would be from day 8-21 but it would mean returning to Tokyo by then.

Hope this helps!
