The bride changes costumes a couple of times during the reception. Usually, she wears a colorful and gorgeous Kimono called uchikake and a white wedding dress and other colorful dresses. The groom usually wears a men's kimono called haoiri-hakama or a tuxedo depending on what the bride wears. During the reception, the married couple sits on a stage observing the guests' speeches and performances. You might be asked to do something at the reception.
Many people sing their favorite songs.
The couple also walks around the tables in the room, lighting the candles and they also cut the cake. There are neither bridesmaids nor a best man at a Japanese-style wedding. An older couple, called Nakoudo, is responsible for managing the wedding and they sit by the couple on the stage. Enjoy the meal while other guests are doing their performances. You might be confused when you should eat or not at first, I say look around and follow what others do at your table.
