I participated on April 3, 2026. The 24-year-old Korean tour guide was handsome, cheerful, and polite. The new assistant guide from mainland China was very friendly and eager to help. We were able to visit every location! In Beppu, we were able to have a trilingual (English, Chinese, Korean) guide explain the chemical reactions of the hot springs, which was very vivid and interesting! Hita City was around the time of the Attack on Titan event, so there were many related signs for photo opportunities. The Suiba Dam was originally a bit underwhelming, but it turned out that the public had spontaneously placed giant sculptures there, rather than it being a major government promotion. I really loved the Attack on Titan museum and wished I could have stayed longer! I could have easily stayed another 30-45 minutes. Yufuin also had a great atmosphere, and the list of recommended restaurants provided by the Korean guide was excellent. Unfortunately, Mount Yufu was covered by clouds. The only thing missing was a little better weather.
