What about JAL domestic flights. According to their website, the SAKITOKU for flights after 26th March will be available from 26th January. Is that for all of 2016 or just the next 3 months or so.
Same goes for some hotels? Do they open for reservation only three months ahead? I've been looking at some hotels, that have no availability after a certain date.
PS: I didn't plan on staying in Tokyo.
