The upper and lower floors are gently connected by a slope in a space where Y-shaped arch columns of laminated timber align. The first floor provides sightseeing information with the railway view of express train “Yufuin no Mori.” The slope, overlooking the beautiful mountain range, leads to the “Travel Library” on the second floor storing travel guides in a calm space. The outside is an observation deck where the nearby Mt. Yufu can be enjoyed.
