Voices have been raised in Japan demanding countermeasures against molestation, which shows no sign of disappearing.

In June, Tokyo's Metropolitan Police Department arrested a man in his 30s on suspicion of groping a female high school student on a Tokyo Metro train running in the capital's Koto Ward.

The man had groped the student two or three times a week for some 10 months since August 2024. Although she got on different trains or changed the time she rode them, the man followed her persistently.
