Saotome Katsumoto insisted that Japan should not forget

In 1967, three years after Japan had shown its new post-war confidence by staging the Olympic games, workmen on the Tozai subway line in Tokyo unearthed the remains of an air-raid shelter. Inside it lay the skeletons of six people huddled together. Two were children; some bones were burned. One adult held Buddhist memorial tablets, from which they could be identified as the wife, daughter and other relatives of Shizuo Tsuzuki, who had left the shelter on an errand and was now a company president. There was the wife he had not seen for 22 years.
