Sennin Buraku (仙人部落) is a manga series by Kō Kojima which ran in the adult magazine Weekly Asahi Geinō, published by Tokuma Shoten in Japan. It is the longest running comic with only one artist, being published weekly since October 1956, and the longest-running strip ever in Japan.[2] By contrast, Golgo 13 is the longest running manga to be serialized in a dedicated manga magazine with Doraemon the second longest, and Kochira Katsushika-ku Kameari Kōen-mae Hashutsujo (Kochi-Kame) the third longest (Asahi Geino is not a dedicated manga magazine). While Sennin Buraku has been running for more years than Peanuts, Charles M. Schulz's strip has more "episodes" as it ran daily rather than weekly.[2] The story was a romantic comedy taking place in historical China, and it was quite risqué for its time. The characters were very traditionally dressed (e.g. all wearing hanfu). The anime has been rerun on Japanese television, and all episodes have appeared on DVD (save for episodes 12 and 19).
Sennin Buraku was the first late night anime, broadcast shortly before midnight on Fuji TV from September 4, 1963, to February 23, 1964.[2]
