Except that according to the news in Japan as I write, there is no mention at all in any North Korean media that there was a missle test. And they just launched another one!

From where I sit, it looks like something for outside audiences rather than an internal thing.
I think that the North Koreans just gave the guy the Chinese least want to succeed the current Japanese prime minister an assured victory in Fall. China had wanted a more 'moderate' guy instead of a guy named Abe who has gone to that shrine that has some war criminals enshrined. They have tried making a big show of who they want and placing direct pressure on the country involved before. In the case of Taiwan and the missle tests they did, the results backfired and they don't seem to have learned the lesson.
In this case, everyone here in Japan seems to expect this thing to go to the security council and the Chinese to scuttle any chance of sanctions. It is noteworthy that it is Japan and not America that is talking about sanctions. When the Chinese shoot down any punishment for tossing missles into Japanese waters as being not worthy of mention
despite making a stink about where a Japanese prime minister prays, then the Japanese will tell them to take a hike.
Oh, and North Korea gets a lot of hard currency from ethnic North Koreans living in Japan. Many gambling profits from pachinko parlors get remitted to North Korea. The goverment has talked about shutting that down. I think it is close to a slam dunk now. Oh, and the police in Japan are not the most effective folks, but they get the job done with little restraint on their bahavior. If they even suspect a parlor owned by a Korean (a lot!!) is a source of cash for North Korea I would not be surprised if it was closed for a long time as various investigations go on. They probably won't even try to hide their targeting a specific ethnic group.
North Korea is not the most liked country here. A few years ago they signed a pact with Japan and agreed to not test any more missles. They also said they would not develop nukes and seem to be denying the messages low level goverment types have sent that they have developed them. But this test is not something they can try to apply a legal fiction to. The Japanese have been mad about the folks North Korea kidnapped and continue to lie about. This thing gave the politicians some legal cover to take harsher measures.
