Buying rail pass

Is it possible to buy 2 tickets of 10 days each, for a same person? For example, to be used in 2 different periods of 10 days.

You can Buy 7 Day,14 Day,21 Day JR nationwiide pass,For smaller region I always Buy monthly season ticket

You can buy more than one rail pass. However, if you are talking about the Japan Rail Pass, it does not come in a 10-day version.

Are you referring to the JR Rail Pass ? If so they only do 7,14, and 21 day tickets. You can buy two 7 seven day passes and use them at separate times, but you can't get a larger pass, use half of it and use the rest later. For instance, if you activate a 14 day pass on the 7th, you have until the 21st at the time it was activated to make use of it, after that it is invalid.

One of the few restrictions is that you cannot buy multiple passes for the same days for the same person , otherwise you can get and use multiple passes no problem. Usage/activation must be within three months of purchase.
