This attraction is remote and difficult to reach, so the shuttle bus tour makes it much more convenient. Since a one-way bus trip from Kumamoto to Amakusa costs 2700 yen per person, the tour includes a local shuttle bus and a round trip from Kumamoto, making it a very affordable option. The guide is a friendly elderly gentleman who mainly speaks Japanese but also a little English. His historical explanations are comprehensive, and if you've read the background information beforehand, it shouldn't be difficult to understand. It's recommended to visit Shimabara Castle and Shimabara Castle on separate days, as there are also related artifacts on display within the castle grounds.
We were lucky to book the 13:00 boat trip this time; it was full of dolphins 🐬, and the kids had a great time watching them.
