My sons are traveling with their friends to Tokyo (Haneda) this December, 2019. (12/22-1/9, two are staying longer and will travel to Seoul and back before departing from Haneda on 1/15/2020.) I’m trying to help them plan an onsen excursion. It’s possible that the group of 5 could do a day trip from Tokyo to an onsen and that the two who stay from the 9th through the15th could head to a more remote onsen like yours before taking off for Korea. One of my sons, Chris, really wants to go to an onsen in the snow and loves crab. Would it be worth it to purchase a rail pass just for one two-night stay at your lovely place? Would there be snow for Chris? Is it easier to get to an airport other than Haneda from Ichi no Yu that would take my son and his friend to Seoul? Is visiting onsen in the snow possible on a limited budget when one is traveling from Tokyo? In keeping with the earlier question regarding airport proximity, would it be better for the pair that stays longer to fly out of a different airport to get to Seoul? If so, should they fly one way out of that airport and one way back to Haneda so they have easier access to Tokyo upon their return? Thanks for your patience with all of these questions! Also, please excuse me if I’m not using the word “onsen” correctly. My sons and their friends would love to enjoy nature and stay in a guest house / inn type of lodging that would include meals if it weren’t to be cost-prohibitive. Thank you in advance for your input!
