This flash animated series is based on the wildly popular manga of the same name (produced between 2008 and 2012) by Mari Yamazaki. It tells the story of a Hadrianic-era Roman architect named Lucius who accidentally travels through time to a modern-day Japanese bathhouse, where he learns about modern building techniques and technologies. Inspired by these innovations, he returns to ancient Rome and builds his own spa. The series was produced as six episodes for Japanese television in 2012. A live-action film was also made by Fuji TV in 2012 and its success led to the production of a sequel, Thermae Romae II, in 2014. An additional online-only animation episode was also released in 2014 in collaboration with the toothbrush brand Reach.
