It seems people just don't want to contemplate the most likely sender of this packet. North Korea have launched numerous rockets in the past, some of them flying over Japan, causing a lot of anger and concern.

Whether this is a response or perhaps last month's harsh words were a run-up to a long planned demonstration. Either way, it's the only explanation that makes sense.
