A 49-year-old man who allegedly incited another man to grope a woman on a train was arrested Tuesday in Wakayama Prefecture, police said.

Identifying himself as a woman named Yui on an online site for gropers and those seeking to be groped, Yoji Isegawa, a senior official at the Osaka Regional Taxation Bureau’s Kainan office, began posting messages asking “Is there anyone willing to grope me?” on April 23.

On his way to work on April 30, Isegawa spotted a 23-year-old woman from Kinokawa, Wakayama Prefecture, on the JR Wakayama Line around 7:15 a.m. who was commuting to her office from Kokawa Station.

He then posted several messages online, including her location on the train, a description of her clothing and the comment: “Come as soon as possible.”

Seeing the post, a 26-year-old man allegedly molested the woman, touching her thighs and stomach, police said. He was arrested at the scene but later released, reportedly because he claimed he thought the contact was consensual.

Isegawa, of Kinokawa, was charged with violating an anti-nuisance ordinance.
