This ceremony, called the "yuino", is an exchange of symbolic gifts between the groom's and bride's families.
Some popular gifts are "konbu", a seaweed whose name can be written to mean child-bearing woman also a long white piece of hemp, representing a wish that the couple will grow old and gray together and a folding fan, which spreads to show future wealth and growth.
The main gift is money (amount is dependent on finances), tucked in a special envelope called a "shugi-bukuro", which has gold and silver strings that are impossible to unknot. The other gifts are given in ornate rice-paper envelopes.
If you married an Okinawan and if either of you have some memorable moments or some helpful tips about getting married on Okinawa for those about to take the "plunge" I would really like to read and share them.
