A long-awaited law to combat stalking, which for the first time recognizes it as a crime and punishes offenders, takes effect today.

According to the National Police Agency, 346 stalking suspects have been identified in the first six months of this year. The number of cases in which people sought help totaled 11,543 during the period, a hefty rise from the 8,021 for all of last year, NPA figures show.

Observers said victims probably believe it is easier to report stalkers now that the phenomenon and the term have gained widespread currency in Japan. Others believe the number of stalkers is also increasing.
