The breakdown of Japan's lifetime employment model has been good news at least for the operator of one of the country's largest jobs websites.

So has the arrival of Prime Minister Shinzo Abe, whose policies helped send Japanese companies' profits to record levels and demand for staff to the highest in 23 years.

Dip Corp. surged 4,955 percent through Friday since elections were called that brought Abe to power in 2012, the biggest gain of the 1,887 firms in the benchmark Topix index. It's risen almost five times more than the next-best performer, as companies flock to the site to advertise for workers.
