As wartime memories have faded in the 57 years since Japan's surrender in World War II, many aging survivors are anxious that the nation might follow the same path to war again.

"(Japan) has not had a single casualty of war and has not killed any foreign people for almost 60 years under the pacifist Constitution," said Aiko Kashima, 77, who visited Tokyo's Chidorigafuchi National Cemetery, which is dedicated to the war dead, on Thursday. "I want the nation to respect this Constitution."

The nation has seen major developments in its security policy over the past few years.
