Splitting one-way train journeys into overnight segments?
I seem to recall that with train tickets in Japan, it's possible to buy a ticket from A to B and get off and on during the journey without extra charge.
I'm not sure if this is still true and if so, the limitations on this (if it's limited to only certain train companies/service types/routes/days).
I'm going to be travelling from Nagoya CentrAir Airport to Osaka Kansai and will be stopping overnight in Nagoya, Kyoto and Osaka along the way; the whole journey will take place over 6-days. Considering it's a one-way journey I'm wondering if it'll be cheaper (and possible) to buy a through-ticket that allows me to get off and on again at the various stations?
If so, where would I go about buying such a ticket?
