In their graphic and unflattering drawings of Japan's fellow Asians and in the unapologetic, often offensive contents of their speech bubbles, two $10 comic books reveal some of the sentiments underlying Japan's worsening relations with the rest of Asia.

They also point to Japan's longstanding unease with the rest of Asia and its own sense of identity, which is akin to Britain's apartness from the Continent. Much of Japan's history in the last century and a half has been guided by the goal of becoming more like the West and less like Asia. Today, China and South Korea's rise to challenge Japan's position as Asia's economic, diplomatic and cultural leader is inspiring renewed xenophobia against them here.

One book centers on a Japanese teenager, Kaname, who attains a "correct" understanding of Korea. It begins with a chapter on how South Korea's soccer team supposedly cheated to advance in the 2002 Word Cup; later chapters show how Kaname realizes that South Korea owes its current success to Japanese colonialism.

"It is Japan who made it possible for Koreans to join the ranks of major nations, not themselves," Mr. Nishio said of colonial Korea.

But the comic book, perhaps inadvertently, also betrays Japan's conflicted identity, its longstanding feelings of superiority toward Asia and of inferiority toward the West. The Japanese characters in the book are drawn with big eyes, blond hair and Caucasian features; the Koreans are drawn with black hair, narrow eyes and very Asian features.

That peculiar aesthetic, so entrenched in pop culture that most Japanese are unaware of it, has its roots in the Meiji Restoration of the late 19th century, when Japanese leaders decided that the best way to stop Western imperialists from reaching here was to emulate them.

In 1885, Fukuzawa - who is revered to this day as the intellectual father of modern Japan and adorns the 10,000 yen bill (the rough equivalent of a $100 bill) - wrote "Leaving Asia," the essay that many scholars believe provided the intellectual underpinning of Japan's subsequent invasion and colonization of Asian nations.

Fukuzawa bemoaned the fact that Japan's neighbors were hopelessly backward.

Writing that "those with bad companions cannot avoid bad reputations," Fukuzawa said Japan should depart from Asia and "cast our lot with the civilized countries of the West." He wrote of Japan's Asian neighbors, "We should deal with them exactly as the Westerners do."
