I participated in the 4/3/2026 tour. The 24-year-old Korean guide was handsome/cheerful/polite. The new Chinese assistant guide was very friendly and eager to help. We were able to go to every location! When we went to Beppu, we were able to have a guide who could speak English, Chinese, and Korean come out and demonstrate the chemical reactions of the hot springs in a very lively and interesting way! Hita City was holding the Attack on Titan event, so there were many related signs to take pictures with. The dam was originally slightly inferior, but it turned out that the giant statue was placed there by the people themselves, and it was not actively promoted by the government. I really liked the Attack on Titan museum and wished I could stay longer! I could have stayed for at least another 30-45 minutes. The atmosphere in Yufuin was also very good. The list of recommended restaurants provided by the Korean guide was excellent, but unfortunately, Mount Yufu was covered by clouds. The only thing missing was a bit of good weather since it rained.
