TOKYO (AP) — A disgruntled worker slammed his car into employees at a Mazda factory yesterday, killing one and injuring 10, stunning Japan just two years after an autoworker went on a deadly rampage in central Tokyo.

Toshiaki Hikiji, 42, was arrested about an hour later on attempted murder charges after fleeing in his car from Mazda's Ujina plant in Hiroshima prefecture, southwestern Japan, police said.

Japanese media reports said Hikiji was a contract worker who had been let go in April. He bore a grudge against the automaker and went there with a knife with the intention to kill, they said.

But Mazda Motor Corp. spokesman Kotaro Minagawa said he had quit in April on his own, citing personal reasons, after working just eight days at the plant, and there had been no reports of troubles. The rampage has revived memories of a stabbing spree in Tokyo's jam-packed electronics shopping district two years ago, also by an angry autoworker, that killed seven people when he slammed a truck into a crowd and then stabbed onlookers.

Hikiji ignored security at the gate and drove into the plant as workers were arriving in the morning. Killed was Hiroshi Hamada, 39, a permanent employee, known as "seishain," the company said.

One male worker remained in critical condition, although details weren't available, Minagawa said.

"I pray for the spirit of the man who was killed, and pray for the recovery of the 10 who were injured," Mazda president Takashi Yamanouchi said in a statement. For decades during Japan's modernisation, its major companies guaranteed jobs for life and offered relatively good benefits in return for loyalty. But automakers, pinched by cost-cutting efforts amid globalisation, are increasingly relying on workers called "haken", who are hired on less attractive contracts than regular workers, often through job-referral companies.

Koetsu Aizawa, professor of economics at Saitama University, said the discriminatory dual system of employment was common at major Japanese companies because regular workers, hired under a lifetime employment system, can't be fired.

"Japan still needs to foster the idea of equal pay for equal work," he said. "What many Japanese feel is that regular workers do little work but have big attitudes and get big money. It is a huge social problem."

The manufacturers can better respond to changes in market demand with haken workers because they cannot generally dismiss regular employees.
