Oversee purchase of JR pass

''When purchasing the pass inside Japan, you are limited to the purchase of one pass, and have to show your passport and your return air ticket'' - Does this mean oversee purchaser can buy more than one pass? (Iie.. I can buy multiple pass...correct?)

That quote is in reference to certain other Japan Rail Passes such as the JR West or JR East Pass. The regular Japan Rail Pass CAN ONLY be purchased outside of Japan.

There is no limit to how many passes you can purchase, however the question is, is it really that economical for you to purchase so many passes and still save money.

It depends all depends on your travel itinerary.

Maybe you can post some of it, to see if you are making a good decision or not.

I've just bought 2 seven day passes for £450 including postage, for my trip to Japan in April. It would cost approx £100 just to get to and from the airport, so figure it'll be good value.

100 US dollars?

It can cost as low as 20 US dollars round trip from Tokyo to Narita Airport.

Note that Japan Rail Passes make sense only if you make long-distance trips within the validity period. If you are staying only within a city, for example Tokyo, then buying individual tickets come out cheaper.

For a 7-day Japan Rail Pass, if you do the Tokyo - Kyoto/Osaka roundtrip on Shinkansen trains within that 7-day period, it pays off :)
