The number of Japanese who feel unfriendly toward China and South Korea has surged to an all-time high, a Cabinet Office survey showed Saturday, reflecting the continued fallout of territorial clashes and deep divisions over wartime history.

The ratio of people who declared themselves hostile toward China rose to an alarming 83.1 percent, up 2.4 percentage points from the previous survey in November 2013, while the same tally regarding South Korea jumped 8.4 points to 66.4 percent, according to the findings.

The ratio is at its highest level since the Cabinet Office carried out the first survey in 1978. The latest survey was conducted from Oct. 16 to 26.
