A Keikyu Line railway employee handed a violent passenger a surprise earlier this week at Yokohama Station by flipping him with a judo throw after the man punched her, the Kanagawa Prefectural Police said.

Hiroshi Ebina, 34, an unemployed Yokohama man, allegedly hit the woman, 21, repeatedly in the face at around 11 p.m. Monday when she stopped him at the ticket gate as he tried to transfer from an East Japan Railway train to the Keikyu Line without paying the full fare from Nakano to Yokohama, police said Wednesday.

The woman, who has a black belt in judo, threw Ebina over her shoulders and pinned him as other staff rushed to help, the police said. She learned the throw in high school, she said.

Ebina, who was arrested on the spot, denied punching her. "I only knocked off her cap," he said.

The police said Ebina boarded the JR Sobu Line at Higashi-Nakano Station in Nakano Ward, Tokyo, with a ¥160 ticket. He then attempted to switch to the Keikyu Line at Yokohama Station but was stopped by the automated ticket gate and the employee when his fare came up short.
