Naruse filmed economically, using money- and time-saving techniques that other Directors shunned, such as shooting each actor delivering his or her lines of dialogue separately, and then splicing them together into chronological order in post-production (this reduced the amount of film wasted with each retake, and allowed a dialogue scene to be filmed with a single camera). Perhaps unsurprisingly, money is itself a major theme in these films, possibly reflecting Naruse's own childhood experience of poverty: Naruse is an especially mordant observer of the financial struggles within the family (as in Ginza Cosmetics, 1951, where the female protagonist ends up supporting all her relatives by working in a bar, or A Wife's Heart, 1956, where a couple is swindled out of a bank loan by the in-laws).
