Already working on another package from the same guy in Japan. Going to include two Touhou T-shirts (one for me, one for my sister as a birthday present), more Japanese candy, and some ramen bowls. If we can win an auction with a low enough price, I'll also be getting a very cheap Japanese retail copy of Earth Defense Force 2017 Portable.
Also, he let me know about the Kit Kat flavors in the package I already got (clockwise from top-right):
-wasabi (yessssss)
-pumpkin pudding
-"Chinese Dessert" (almond jelly)
-"Adult Taste" (dark chocolate)
-vanilla ice cream
-raspberry
