While Fukuda has made it clear that he will not visit the Yasukuni Shrine, 160 other parliamentarians paid homage at the site last month, an indication that conservative forces in Japan remain strong and that future prime ministers may not abstain from visiting Yasukuni. And Japan has so far failed to live up to its treaty obligations to clean up between 700,000 and two million chemical weapons that were abandoned in China by the Japanese army at the end of World War II, another potential flash point if any of these weapons causes casualties in China.
