I spent three nights from 29 october to 1 November at the Ryokan Takenobo and I had a marvellous time. The owner was very accommodating and always ready to support despite the language barrier (I am still working on my Japanese). The bathroom is just amazing and the breakfast just the right amount with excellent fresh fishes, tofu and eggs from the local producers. What else can you ask for?
It was my first Ryokan experience and I would definitely do it again. And if possible repeat my visit to Okinoshima as well!
Thanks a lot for the warm welcome and the great tips :)
