TOKYO (REUTERS) – No radiation had been detected from North Korea’s nuclear test on Wednesday (Jan 6) at Japanese monitoring posts, Japan’s top government spokesman said. 

“As of 4.45pm this afternoon, no radiation has been detected at any Japanese monitoring posts,” chief cabinet secretary Yoshihide Suga told a news conference.

He added that Japan could propose to the United Nations various economic and other sanctions against North Korea in cooperation with the United States, but did not give details.

North Korea on Wednesday (Jan 6) said it had successfully tested a miniaturised hydrogen nuclear device, its fourth nuclear test, claiming a significant advance in the isolated state's strike capability and setting off alarm bells in Japan and South Korea.
