The number of reported cases of domestic violence between couples in Japan for the first six months of this year is up by 46.3% over 2011, according to National Police Agency data.
The NPA said the number of confirmed cases of domestic violence between married couples and couples living together totaled 2,016, an increase of 600 over the January-June period in 2011, TV Asahi reported. Of the victims, 94% were women.
Some analysts believe the sudden increase is due to victims becoming more likely to report such crimes to police.
The NPA said the biggest spikes were in Saitama, Chiba and Gunma prefectures.
Meanwhile, NPA data showed that in the three tsunami-hit prefectures of Iwate, Miyagi and Fukushima, confirmed criminal cases decreased by 1,500 to a total of 19,086, TV Asahi reported. The decrease has been attributed to the greater number of police officers stationed in the region and an increase in patrols.
