The Big List of Japanese Candy Boxes
Here's a list of every Japanese candy subscription box I've heard of. These are services that for a monthly fee send you candy from Japan periodically.
I don't go actively looking for these, but whenever I hear of a new one I add it to this list. If you know one that is missing, drop me a line.
