As some of you may know, Japan Post has stopped accepting parcels to the US that weigh over 16 oz. (about 430 grams) except for SEA parcels. It has something to do with new security measures in the US that Japan hasn't set up yet. The only way you can send items is if you have a contract account with the post office. I can't imagine they'll have this policy for long, but for the time being if you don't have an account I wouldn't plan on sending those Christmas presents home anytime soon.
