Japan's Finance minister Yosano seems to have been accepting donations from a dummy front set up to pay politicians for more than twenty years. He may possibly have acted illegally in accepting the money, though my guess is he didn't. Maybe he knew the source was dubious, but probably he did not. It hardly matters.
The elections are a couple of months away and as finance minister he's one of the most high-profile members of the cabinet. This is not a good time for the Aso government to remind everyone of the low-grade sleaze and shady deals that has become a hallmark of the LDP era. It's perhaps especially inconvenient that it's the minister of finance, who is supposed to be the man of the hour in this economic crisis. A bit difficult to send him out to calm the electorate if the journalists keep bringing up suspect campaign donations.
Also of note: The monthly Japan blog matsuri is up, with the theme of Living on a budget in Japan. Plenty of good entries there.
