Asked whether Japan needs to change its diplomatic and other positions on China, 51 per cent of people said it should be stricter, the Mainichi Shimbun daily said about the survey.

The ratio was twice as large as the 26 per cent who wanted Japan to be 'more friendly' towards China, according to the May 1-2 telephone poll of 1,042 adults nationwide.

Mr Hu heads to Tokyo on Tuesday - the first Japan visit by a Chinese president in a decade and only the second ever.

Mr Hu said on Sunday his trip would have the atmosphere of a 'warm spring'.

Japan is his first foreign destination since major protests broke out in March against China's rule in Tibet.

China's ensuing crackdown has caused an international uproar and cast a shadow on Beijing's cherished Olympic Games.

But unlike European leaders who have flirted with shunning the Olympic opening ceremony, Japanese Prime Minister Yasuo Fukuda said he hoped to go even before Mr Hu could formally extend the invitation.

Mr Fukuda, struggling to reverse rock-bottom approval ratings caused by domestic issues, has championed reconciliation with China throughout his career.

The Mainichi said the poll results appeared to reflect unhappiness with China's insistence that the Tibet issue is an internal matter, as well as concerns over the safety of food imports from China.
