Tatayama-Kurobe Alpine Option Pass question

Hi,
For the Tatayama-Kurobe Alpine Option Pass, the web site states it's valid for 5 days. Does this mean 5 days from the day of purchase or from the day of first use? I have not found an answer to this on any of the JR site information brochures. I would like to purchase it when I arrive NRT on May 20, and initiate it's use when I get to the start of the route on May 27th. That's more than 5 days after the purchase - but if the validity is 5 days from the date of first use, then that might be ok?

Thank you!

First day of use.

According to the official webpage
: This ticket is not valid for use on the day of purchase.
: This ticket is valid for 5 consecutive days.
So, it is clear that the 5 days of validity are not counted from the day of purchase.

Hi, just to clarify, I need to know, does the 5 days start the day after I purchase it, or do the 5 days start from the date I validate it at the station? What I need to know, if I buy it when I land in HND on May 19th, and don't use it until May 27th, do my 5 days start on the 27th?

Thank you,
Laurel

You seem making too much of a simple matter....

On May 19, you purchase your ticket which should be valid from May 27 for 5 days; you specify the first day as May 27.

or do the 5 days start from the date I validate it at the station?

There is no step for a passenger to validate this ticket.
(If validation were necessary, that should be mentioned clearly in every official brochure.)

Note:
This Tateyama Kurobe Option Ticket is a one-way ticket, not a pass to let you travel back and forth freely.
Once you start to use your ticket, it does not allow you to go back.

Enjoy your trip!
