This ceremony marked the transition from child to adult status and the assumption of adult responsibilities. The age of participation varied throughout history and depended on factors such as sex, political climate, and social status.

Moreover , Kobayakawa was known to attack women and children during the campaign , an act that is despised by many of his fellow commanders . Before the battle of Sekigahara , Kobayakawa happened to be in Osaka and acted as though he would go along with Mitsunari , even though he had intended to betray him , having secretly communicated with Ieyasu . Knowing Kobayakawa held ill feelings , Mitsunari and tani Yoshitsugu promised him two additional domains around Osaka and the position of kampaku ( until Toyotomi Hideyori grew old enough to rule ) if he helped them to victory .
