I don't understand Japanese very well, and I thought I would need to ask my travel companions to help translate the whole time. However, the guide had translation equipment on hand. Although there were times when the translation was blocked due to network communication issues, the guide's simple and detailed explanations gave us the opportunity to learn about the history of the "infiltrated Christians" in Amakusa. The whole trip was very rewarding! I would love to experience it again next time!
