Excellent guide by Miss Kong ! she is very knowledgeable, friendly and funny ! very clear on all instructions and to me the highlight of our kyushu trip. The reason i chose this trip was due to the difficult public transportation but this tour make it possible for it to be done in one day ! the driving was enjoyable , toilet breaks mentioned by Ms Kong all the time, she also gave heads up if the weather in Mt Aso is good or not. If not good the trip to Mt Aso crater might be cancelled but thankfully the weather was good, and its not anybodys fault if the weather is bad ! Ms Kong speak mainly chinese and due to my limited language she does her best to speak English at times , and we really appreciate her effort. I would definetly recommend this tour to everybody that wants a full Mt Aso tour that leaves from Kumamoto ! FYI i bring a 5 year old and she did enjoy it very much also !
