Funaoka Onsen is a onsen public bath house located in Kyoto, Japan.
The building is made out of wood and dates to 1923. The authorities registered it as a Tangible Cultural Property. The front entrance gate features a karahafu undulating curved gable at the top, a feature that can be found often in Japanese castles. The interior has ornately covered panels out of wood which depict mythological stories. It was carved by artists who work for the Imperial Court and it took them around 10 years to complete.
