Japanese wedding customs fall into two categories: traditional Shinto ceremonies, and modern Western-style weddings. In either case, the couple must first be legally married by filing for marriage at their local government office, and the official documentation must be produced in order for the ceremony to be held. Traditionally, marriages were categorized into two types according to the method of finding a partner—miai, meaning arranged or resulting from an arranged introduction, and ren'ai, in which the principals met and decided to marry on their own—although the distinction has grown less meaningful over postwar decades as the proportion of miai matches has dwindled.
The Japanese bride-to-be may be painted pure white from head to toe, visibly declaring her maiden status to the Gods. Two choices of headgear exist. One, the watabōshi, is a white hood; the other, called the tsunokakushi, serves to hide the bride's 'horns of jealousy.' It also symbolizes the bride's intention to become a gentle and obedient wife.
Traditional Japanese wedding customs (shinzen shiki) involve an elaborate ceremony held at a Shinto shrine. Japanese weddings are being increasingly extravagant. However, in some cases, younger generations choose to abandon the formal ways by having a "no host party" for a wedding.[2] In this situation, the guests primarily consist of the couple's friends who pay an attendance fee.
Couples are officially married once they have successfully submitted the required documents to the city hall registrar to change their status in their family registries. No ceremony of any kind is required under Japanese law
