According to Mainichi Shimbun(Mainichi Daily News), Kanno Onsen Ryokan has been suspending its operations since last December. Reason includes owner's sickness. Currently, the family is struggling to find a way to restart/handover its operation.
I visited the ryokan last year but posted the information in March. Apologies for the confusion it may caused.
I gave a strong "5" to Kanno Onsen Ryokan. There's no place like Kanno Onsen which has that variety of superb onsen. As an onsen blogger having passion in spreading good onsen to the world, I truely hope that the owner recovers from sickness and that Kanno Onsen Ryokan will restart its operation in the near future.
If no one is doing the operation, I will! It is that good.
