will surely mean a step back from constitutional revision," said political analyst Takao Toshikawa, editor of the newsletter TokyoInsideline.

That is as much due to timing as any personal convictions Fukuda may hold. Following the setback to Abe's LDP in the July election, the LDP-New Komeito ruling coalition lost its majority in the upper chamber, making it more difficult to drastically alter the Constitution or change long-standing basic defense policy.

"The current situation is not good for such moves. I wonder if I should talk about things that won't be realized," Fukuda said in an interview with Kyodo News last week.

Barring other political upsets, the political climate will remain unfavorable to the ultraconservative wing of the LDP for some time to come.
