Since it was quite late when we arrived at Tai Po Catholic Church after visiting Managaha Island, besides the church itself, the souvenirs inside were also worth buying. Unfortunately, by the time we finished exploring the facilities and were ready to go to the souvenir shop, it was already closed.
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.
My family and I loved it. Even though it was only 7 degrees Celsius, it was worth it because the scenery was so beautiful.
