Original: 南海トラフ巨大地震

In Miyako, Iwate Prefecture, a high school held an evacuation shelter training exercise, reported on October 7, 2026, as Japanese news coverage continues to focus on preparedness for a possible Nankai Trough megaquake. Interest in the topic has surged as communities review disaster plans, and the government continues to warn that a major earthquake along the trough could cause massive casualties and damage across western and central Japan.

Why now: Ongoing government warnings about a potential Nankai Trough megaquake keep Japanese audiences highly focused on earthquake preparedness news.
