When a public junior high school teacher in Tokyo teaches about Japan's acts of wartime aggression, some of her students ask why they should feel responsible for what people did 60 years ago.

The teacher, who has taught social studies for more than two decades, believes students should find the answer themselves, and that history textbooks should provide sufficient information to help them think the issue through.

"I think it's inappropriate for (history textbooks) to give one-sided descriptions for either Japan's aggression or the damage it suffered" in the war, she said, asking that her name not be used. "It's important to look at a historical event from various viewpoints."
