|“||We need a rakugo that never changes. That's the essence of rakugo.||”|
— Sukeroku, ep 8
Rakugo (落語) is comic storytelling, normally done on a stage (高座 kouza) with a towel and a folding fan. A person who does rakugo is known as a rakugoka (落語家). It can be translated to "descending stories", hence the name of the Kodansha USA translation. It often relies on ludicrous endings/plots and wordplay to create humour.
Characteristics of rakugo
- Characters are distinguished through body language and speech.
- Rakugo is normally done using a towel and folding fan on a stage and done in seiza position (sitting, normally on a cushion or on the floor, with legs tucked under the body). It is done in a kimono, which is why Sukeroku does not need to have any other clothes aside from the ones he already owns. There is sometimes a microphone placed in front of the rakugoka.
- There is a monologue performed before the story, which allows a rakugoka to gauge his audience and thus tell an appropriate story.
- Women used to not be allowed to perform rakugo; however, currently women are allowed to perform it. 
- When the rakugoka goes on to the stage, he is accompanied by music, normally of the kouta variety.
- Stories range from 10 minutes to 40 minutes, although the usual time range is 30 minutes.
- Kyoto-stye rakugo can involve a table which the rakugoka bangs on.
Ranks (from lowest to highest)
- zenza - "the lowest stage of performer". Means "opening performance".
- futatsume - literally means "second" or "second place".
- shin'uchi - does not need to practise as much as a futatusme, and is considered a "master" by underclassmen. It is at this level that a rakugoka can take on an apprentice, or many apprentices.
Rakugo apprenticeships and associations
Rakugo apprentices usually have a strict training period of 3 to 4 years, but because Hatsutaro and Kikuhiko were essentially abandoned by their parents, they had much longer apprenticeships. During their apprenticeships, they must behave as their master requires them to, including not smoking, drinking or going on dates, depending on the master. They require permission to perform certain stories, and must learn the tricks of the trade through rote learning, listening to audio/video recordings and watching their master.
As a rakugo apprentice, a person needs to receive a stage name before they can perform. The rakugo master can choose to pass on a certain stage name to their student or not. The biggest example of this legacy is the Yurakutei legacy in the series.
