Japanese and Chinese meanings clearly diverge.
Chinese sources list the meaning as TO SHAME someone, to BE ASHAMED, perhaps as those「youthful hearted, young morality」who sometimes make foolish decisions bringing SHAME to one's parents or DISGRACING themselves,「repeatedly using both hands on small, youthful stream (with emphasis)」or「repeatedly bobbing head with family and emphasis on small youth」or「dying young due to morality, moral nature」with other possible combinations connoting SHAME and DISGRACE. In addition to the obvious meanings, in the good old days in Asia (not so long ago), it was a shame not to give birth to a son, and of course the parents were blamed by everybody for「doing something to deserve such a horrible curse」as to not give birth to a son:「dying young with emphasis on small mons pubis」
「Couples whose one child turns out to be a girl are in an even more painful dilemma: cultural norms dictate that daughters marry out and transfer their emotional and economic loyalties to their husband's family. Since sons alone support their parents through old age, a couple with only a daughter is left with no source of future economic security. Rural China has no system of old age support, thus farming couples without sons are faced with the specter of destitution once they are too old to work the fields. Given these conditions, a number of rural couples have responded by exercising a form of gender selection by committing infanticide on their female neonates. Infanticide, particularly female infanticide, was common in traditional China. Natural hardships such as famines, floods, widespread disease, and overpopulation often converged with cultural norms that favored sons and encouraged hard-pressed families to abandon or kill their infant daughters.」

Japanese meanings infer「young and small with emphasis」or「intent」or「stream of emissions from heaven with emphasis」or「young tender fresh-looking mons pubis and emission stream with emphasis」as thanks to the gods, GRATITUDE for a child, or being given a child by relatives if a couple was unable to conceive one of their own and BECOMING INDEBTED TO ANOTHER. Other interpretations are possible, of course, such as grateful feelings associated with the simple enjoyment of youthful pussy, or, bobbing head with both hands and emphasis on a stream of emissions, and so on.
