^ ^ ^ A big thank you
phoneticduck for putting me onto this.
What I did not know is that JAL offers
five different "Visit Japan" style fares. The cheapest allows travel between TYO and
Tohoku at only 5400 JPY per sector(!).
There was formerly a Kyushu version of the fare allowing travel between TYO/OSA and Kyushu for 5400 JPY per sector as well. However that expired by the end of last year.
These all book into full Y class and reservations need only be made for the first sector; the others can be left open and changed at will (except the GEXPLORE fare which books into G, no changes).
What a great set of products. A shame there is no J equivalent but you can grab it on the day, subject to availability.
