The Takeo Onsen Loumen, a two-story wooden structure painted a vibrant vermilion and reminiscent of a dragon palace, stands as a symbol of Takeo Onsen. Designated as an Important Cultural Property, this architectural masterpiece was designed by Kingo Tatsuno, the architect behind Tokyo Station. Completed in 1915, the Loumen boasts a unique Tenpyō-style construction, built entirely without nails. Its intricate wooden framework and striking appearance continue to captivate visitors. On the second floor, you'll find intricate carvings of four Chinese zodiac animals—rat, rabbit, horse, and rooster—with the remaining eight believed to be located in Tokyo Station. Surrounding the Loumen, visitors can discover a wealth of historical and cultural attractions, such as the Takeo City Library and the Nabeshima Motoyoshi Monument. The library, designed by renowned architect Kengo Kuma, is a stunning building that houses not only books but also a cafe and event spaces.
