Jin and Thermae Romae are both series that are focused on a protagonist who finds themselves the victim of spontaneous time-travel, using their knowledge of modern customs and technologies in order to further their craft for the good of others within the time period they reside.
While Jin is about a modern Japanese surgeon stuck in the Edo period of Japan, Thermae Romae is about an ancient Roman architect traveling forward in time to modern Japan.
