sato considers "late spring" to be "the next major development in the home drama genre," because it "initiated a series of ozu films with the theme: there is no society, only the home. while family members had their own places of activity—office, school, family business—there was no tension between the outside world and the home. as a consequence, the home itself lost its source of moral strength." yet despite the fact that these home dramas by ozu "tend to lack social relevance," they "came to occupy the mainstream of the genre and can be considered perfect expressions of 'my home-ism,' whereby one’s family is cherished to the exclusion of everything else."
