The weather was great, and the views of Mount Aso and Takachiho while boating were truly beautiful. Plus, our professional guide, Jimmy Yanagi, was witty and humorous. Highly recommended!
Mr. Liu's cooperation was excellent 👍, making our trip very smooth and allowing us to get excellent rest during our business trip. He's definitely worth recommending again and again.
The weather was great, the tour guide was friendly, and even the driver was very kind. Although it was a pity that we couldn't go to the volcano viewing platform due to wind direction, I still really enjoyed and appreciated the day trip.
