"What is life?" was the theme of a special class at a school hit by the March 2011 tsunami disaster. The goal was to help students share their experience of losing loved ones in the disaster, which they had rarely done at school before. Given the chance to write the sorrow bottled up inside them, they gradually started to open up and express their feelings. Their constant attempts of the class helped them move forward. This is a record of the year-long journey taken by these 15-year-olds.
