From The Economist:
Yotaro Kobayashi, the high-flying Chairman of Fuji Xerox, got some threatening packages after he criticised Japan’s prime minister, Junichiro Koizumi, for visiting a shrine honouring the Japanese war dead. A package sent to Mr Kobayashi contained a bullet, and Molotov cocktails (which failed to fully ignite) were found outside his home. Yasukuni, the controversial shrine that Mr Koizumi visited, was once a famous backdrop for war propaganda and emperor-worship. The dead commemorated there include convicted war criminals from the second world war.
The prime minister’s visits to Yasukuni have earned him criticism from a number of Japan’s neighbours, which are still bitter about the country’s long history of waging war on them. China in particular has said the visits show a lack of remorse from Japan, and has called for them to stop. Mr Kobayashi has been a target of right-wing groups since late last year, after he said the visits were fraying relations between Japan and China, which have been fragile lately.
