Japanese weddings, with their interminable sentimental speeches and stage-managed atmosphere, can be more grueling than heartwarming for some guests, and what non-Japanese usually fail to realize is that they are expected to pay for the privilege of enduring these festivities. Unlike funerals, where guests pay their respects, eat a little food, and leave, friends and relatives who attend wedding receptions pay cash gifts to the happy couple. According to the bridal magazine Zexy, while there are no hard and fast rules regarding the amount of the gift, the customary contribution is ¥20,000-30,000 for "friends and colleagues" of the bride and/or groom, ¥30,000-50,000 for a boss or supervisor, and ¥50,000-100,000 for relatives (calculated as couples). In the West, guests are expected to celebrate by giving something, too, but they usually offer gifts that are presumably for the couple's new life together. Japanese cash gifts are meant to go toward paying for the wedding.
Zexy estimates that a couple spends on average about ¥1 million on their wedding themselves, and whatever difference there is is made up for by cash gifts from guests (goshuki). That means the more guests they invite (and actually show up), the more the couple can spend. In the wedding business parlance, there are two general types of wedding receptions. Hade-kon are "showy" weddings, meant to stress appearances; while omotenashi-kon emphasize "hospitality" by putting guests first. Hade-kon are not necessarily more expensive on a per-person basis, and in any case the venue will make as much money as it can regardless of the real intentions of the people involved. Anyone who has been to a Japanese wedding will probably note that there's always way too much food and the presents the couple gives out to guests (selected from a list provided by the service provider) are usually superfluous.
