Dear Family and Friends, the best gift of all would be your presence on our Big Day. If you insist on getting us a gift, we are following the Asian tradition of money gift. 

"Guests can offer the couple goshugi -- money -- in a festive envelope either before or after the wedding ceremony." 

Also it would be kind of difficult to carry all the gifts back to Tokyo, Japan which will be our home in the next two years! Thanks in advance!
