For a moment there I thought it was going to be a company by one of HN's users: Candy Japan. Same business: Japanese candy subscription service. But the user profile says Candy Japan is no more. :-(
I used to get boxes from them. Candy Japan is/was a one person operation run by a Finnish guy named Bemmu, who also blogged about his life in Japan.
His user profile is here: https://news.ycombinator.com/user?id=bemmu. It now says it was shut down, so I guess it's official. Weird that he wouldn't update the site, though, which just says it's temporarily paused.
I'm not surprised that decided to shut it down; it seemed like a lot of work, and there are now a number of competitors doing the same thing at a much higher volume, with free world-wide shipping, glossy packaging, and so on.
