Ichiro Fujisaki's four-year stint as Japan's ambassador to the U.S. saw turbulent events — the Great East Japan Earthquake, shifting political power in Nagata-cho and President Barack Obama's re-election — to name but a few.

And now, Fujisaki, whose posting ended in November, finds himself back in Tokyo at a time when the country is about to hold a general election that could see the Liberal Democratic Party return to office, threatening further political turmoil.

"It doesn't matter whether it will be one-party rule or a coalition government. What is important is to have a stable government that can make policy decisions," Fujisaki, 65, said in a recent interview with The Japan Times.
