14.5 billion yen. That's how much money, if not more, that may be lost if 471, 567 people don't claim their checks from the Japanese government. A while back, the Japanese government offered free money to its citizens, akin to the stimulus checks that were sent out in America. According to Mutantfrog Travelogue and Nikkei, the reason why all these people aren't getting their money is that their listed address and their registry information don't match up.
So, they could've simply written the wrong kanji, or they hadn't updated their information with the local precinct. The basic amount was 12,000 yen ($120) per person, but could easily be a lot more, since the information was per-household for Japanese families -- meaning a family of five would lose out on at least 60,000 yen.
So, I guess this teaches you to always double check your information when filling out forms, eh? The question is, what will the Japanese government do with all this money? The applicants will be ineligable to reclaim their money after six months, and so we'll have to see how the government employs it. Perhaps they'll put it towards making more K-On!
That's what I call money well spent!
