With the impression of the threat of nature still fresh in our minds after visiting the damaged houses on Mount Unzen and the Gamasu Dome, we boarded the ferry. It took about 40 minutes from Shimabara Port to Kumamoto Port. The view from the sea further deepened our understanding of the greatness of the Earth.
Our group of 12 friends was advised by customer service to rent an 18-seater minibus. We could easily fit all our luggage in, and there were still seats available for thick coats and bags, making for a comfortable three days. The best part was the driver's professionalism and friendliness; he spoke fluent Mandarin and was patient with the young children. It started snowing on the first night, and some roads were closed the next morning, requiring us to change our plans. The driver helped us call nearby indoor attractions to check if they were open, and we finally found a monkey theater where the children played in the snow – it was cold but fun!
The original plan was to spend an hour there, but that wasn't enough. If you're interested in history and want to explore each building and room in detail, you'll need to wait at least 1.5 hours.
