LONDON -- Prime Minister Shinzo Abe has the reputation of being a tough nationalist. So far, however, he has shown himself to be a pragmatist in foreign-policy issues. His early visits to China and South Korea demonstrated that he wants to improve bilateral relations, which have soured in recent years. He has wisely eschewed mention of the Yasukuni issue. He realizes the vital importance of the U.S. relationship and understandably takes a tough line on North Korea.

But there have recently been some developments, apparently reflecting a recrudescence of rightwing nationalism, that are potentially damaging to Japan's world image. I was disturbed to see recently a report of a discussion between Sophia University professor emeritus Shoichi Watanabe and Foreign Minister Taro Aso in which the foreign minister and his conservative interlocutor made remarks that suggest that they take a revisionist view of Japanese history.

Watanabe once again attempted to deny known facts about the Nanjing Massacre and urged the foreign minister to promote his revisionist theories of history. The foreign minister's failure to reject Watanabe's proposals and his general line in the interview suggests that he is also a historical revisionist. The emphasis on Japanese uniqueness and on the Shinto view of life and death read very oddly.
