The highlight of the Japanese wedding ceremony is San-san kudo (three times three exchange) or the sharing of sake in which the taking of vows is solemnized. Three small cups are filled with sake and stacked on top of each other. The groom takes a sip from each of the three cups followed by his bride who does the same. The cups are then passed onto the groom's parents, then the bride's. Finally if the couple met each other through a tradition called Omiai where a matchmaker was involved, the matchmaker will drink last and the couple is then officially married.
