As those sentiments took root, the Japanese began acquiring Caucasian features in popular drawing. The biggest change occurred during the Russo-Japanese War of 1904 to 1905, when drawings of the war showed Japanese standing taller than Russians, with straight noses and other features that made them look more European than their European enemies.
"The Japanese had to look more handsome than the enemy," said Mr. Nagayama.
Many of the same influences are at work in the other new comic book, "An Introduction to China," which depicts the Chinese as obsessed with cannibalism and prostitution, and has sold 180,000 copies.
The book describes China as the "world's prostitution superpower" and says, without offering evidence, that prostitution accounts for 10 percent of the country's gross domestic product. It describes China as a source of disease and depicts Prime Minister Junichiro Koizumi saying, "I hear that most of the epidemics that broke out in Japan on a large scale are from China."
The book waves away Japan's worst wartime atrocities in China. It dismisses the Rape of Nanjing, in which historians say 100,000 to 300,000 Chinese were killed by Japanese soldiers in 1937-38, as a fabrication of the Chinese government devised to spread anti-Japanese sentiment.
The book also says the Japanese Imperial Army's Unit 731 - which researched biological warfare and conducted vivisections, amputations and other experiments on thousands of Chinese and other prisoners - was actually formed to defend Japanese soldiers against the Chinese.
"The only attractive thing that China has to offer is Chinese food," said Ko Bunyu, a Taiwan-born writer who provided the script for the comic book. Mr. Ko, 66, has written more than 50 books on China, some on cannibalism and others arguing that Japanese were the real victims of their wartime atrocities in China. The book's main author and cartoonist, a Japanese named George Akiyama, declined to be interviewed.
Like many in Taiwan who are virulently anti-China, Mr. Ko is fiercely pro-Japanese and has lived here for four decades. A longtime favorite of the Japanese right, Mr. Ko said anti-Japan demonstrations in China early this year had earned him a wider audience. Sales of his books surged this year, to one million.
"I have to thank China, really," Mr. Ko said. "But I'm disappointed that the sales of my books could have been more than one or two million if they had continued the demonstrations."
