Yasuda Kasai CIGNA Securities Co., a Japanese-American joint venture formed to provide 401(k)-style pension plans, aims to grab 5 percent of a market it estimates will be worth 30 trillion yen in 10 years, said Akimasa Oshima, president and chief executive officer.

"It is a life-size target," Oshima said in an interview. That kind of market share could translate into 500,000 to 600,000 workers enrolled in the pension company's plans, assuming 50 percent to 60 percent of all firms adopt such a system.
