Nobuko Miyamoto was married to director Juzo Itami.
The second mistress performs an air chop gesture when receiving a stack of ¥100,000 bills placed on the table as her monthly allowance. This gesture is a deliberate mimicry of the ritual sumo wrestlers perform when they receive prize money after winning a bout. Known as "tegatana," or "hand sword," this Shinto-inspired ritual symbolizes humility and detachment from materialism. By symbolically "cutting" the money with the hand, the gesture serves to distance oneself from greed and demonstrate respect for the sacred, non-materialistic aspects of the exchange.
