Who Is Sadakichi the Apprentice (Sada-don)?
A shop boy dragged along by the retiree
Sadakichi is a name often given to a young shop apprentice (kozo) in classic rakugo, and in Cha no Yu he is the retired master's sidekick and attendant.
In Episode 9, he knows no more about tea etiquette than his master but plays along anyway, running out to buy green soybean flour and using muku bark to make foam, going along with every one of the retiree's whims. After drinking the mysterious tea with his master every day, he finally upsets his stomach. His role is to make the retiree's bluffing grow even bigger.
