One chikan in Osaka clearly did not want to get caught for his actions:

A man who groped a girl on a morning rush-hour train jumped onto the tracks and disrupted operations in Osaka, West Japan Railway officials said. At around 8:15 a.m., a man apparently in his 30s and wearing a business suit allegedly touched a 15-year-old girl on the Osaka Kanjo Line and other passengers caught him red-handed, officials said.

When the man was pulled off the train at Osakajo Koen Station and was about to be handed over to station staff, he jumped onto the tracks and fled toward the next station, Morinomiya, the officials said. To ensure safety, JR West suspended more than 25 train runs, affecting 28,000 passengers, they said.

According to Mainichi, the man managed to evade capture. Authorities are searching for a man “who appeared to be in his 30s and was wearing a business suit.”
