Meanwhile, the opposition Liberal Democratic Party, which ruled for much of the half-century to 2009 and thus bears a large share of the responsibility for lax safety standards in the nuclear-power industry, is also seeking Mr Kan’s early resignation. It may pursue a censure motion in parliament with other opposition parties.

All this, even though the public shows no enthusiasm for yet another revolving-door prime minister. To all but the political classes engaged in plotting, a leadership struggle for its own sake at a time when the focus should be on dealing with nuclear and humanitarian concerns seems crazy. None of the main parties has offered a compelling alternative for how to recover from the disaster. This includes the DPJ. Far from using the crisis as an opportunity to push for reform, the party’s secretary-general, Katsuya Okada, says things should “settle down” before the party proposes rebuilding initiatives, new energy policies and a rise in the consumption tax to pay for reconstruction.
All is not hopeless, however. On April 26th Makoto Iokibe and Jun Iio, the two (non-government) leaders of Mr Kan’s new Reconstruction Design Council, laid out their early thoughts on how to rebuild Tohoku, the shattered north-eastern region of Japan’s main island where almost 26,000 have died or remain missing, presumed drowned. Though they believe it will take at least a decade to recover, their vision, especially compared with the lack of it in politics, is daring. They want to let locals play the main role in reshaping their blighted communities; rebuild in ways that suit elderly residents; use ideas from business and abroad; and limit the influence of the government in Tokyo, which they believe dangerously overcentralises decision-making. Japan’s usual way of doing things, Mr Iio insisted, was not up to meeting challenges on this scale.
The same day, Mr Kan announced his decision to appoint an investigative panel into the Fukushima chain of accidents. Nuclear officials believe Japan needs a quick and thorough investigation, including international experts, if it is to gauge the safety of other nuclear plants. In particular, it will have to look into what happened on the night after the tsunami, when there was a delay in “venting” pressure building up in one reactor. Officials worry most about the Hamaoka plant in Shizuoka prefecture, which is reckoned to pose the greatest risk to Tokyo should a quake strike nearer the capital. Hamaoka is of a similar type and age to Fukushima Dai-ichi.
But whether the reconstruction council and nuclear investigation promote deep changes in the way things are done in Japan rests largely on the prime minister’s powers of leadership. Only Mr Kan can make sure that the good ideas which emerge do not sink into the Tokyo swamp of bureaucrats and politicians. With some of his party against him, and the opposition unco-operative, it is not even clear that Mr Kan will get emergency budgets approved by the Diet, let alone be able to promote decentralisation and sound energy initiatives. It might help if ordinary citizens spoke out strongly for change. But apart from sporadic protests against TEPCO in the past week, they have yet to make their voices heard above the petty politicians.
