My sister an I had a wonderful time, its our first time and definitely won't be the last.
We spent 5 days in Kyushu and wish if was 5 weeks or months! We fell in love with the Onsen experience and all the Japanese food we've had,some were heavenly. Although not many local people speak English they all are very helpful and nice. All the places we visited we enjoyed everything.
Yufuin in particular is a little gem, it is a qaint and peaceful place, it has the best Onsens that we felt truly relaxed and recharged, in body and spirit. We stayed at Yufuin Sansuikan, its at a good location and the staff made you feel welcome all the time, their Onsen were 1st class and the food are unforgettable. The rooms are comfortable but can do with a lick of paint.
At Beppu we enjoyed the hell springs tour, our hotel Shiragiku was also very nice, unfortunately we found the tatami room and Japanese dining room are uncomfortable, we will learn the lesson and request for western rooms next time. It was a lovely hotel and its onsen was very good too, food were excellent.
We spent 3 days in Kyoto and enjoyed many cultural experience, gardens and cheery blossoms there. All in all we have covered a lot in such short space of time, now we look forward to visit Japan again.
