The scenery was beautiful, and the boat trip was so much fun that it was definitely worth the trip! Brother Sun from Gogoday was very responsible, and thanks to his recommendation, I was able to choose the most unique Aso volcano ash souvenir. It's completely exclusive to this area and can only be found here. I'm so happy!
The grass turned into fog, and the Aso Boys event was temporarily suspended, which was a bit disappointing. However, the friendliness of the local merchants and the delicious souvenirs made up for the aforementioned shortcomings.
