When a couple decides to get engaged, they will pick a married couple as go-betweens (nakoudo). The bride and groom-to-be usually request the groom-to-be's boss or a former teacher to be their mentor. The go-betweens will serve as a helper for various events from the engagement ceremony to the wedding. The go-betweens are also supposed to give advice to the couple even after they are married.
When the go-betweens are selected, they will decide to plan for "yuinou."
Traditionally, the engagement gifts used to be brought by the go-betweens or another delivery person to the fiancee and fiancee's houses.
Nowadays, instead of delivering the gifts, both the bride and groom-to-be, their parents and the go-betweens gather at one place to hold the Yuinou ceremony to save troubles.
In addition to the monetary gift from the fiance and the return gift from fiancee, they exchange several other items. They are called "Yuino-Hin", consisting of five, seven or nine items.
