system is not designed for providers to earn profits," Hattori said.

However, she said the way Comsn tried to expand its business was particularly despicable. Before the fraud scandal mushroomed, if Comsn got caught inflating the number of employees at a nursing-care facility, it would shut the facility down to avoid disciplinary action.

Hidekatsu Watanabe, a senior analyst at Mizuho Securities Co., said he hopes the Comsn scandal serves as a warning to service providers not to break the law and encourages them to build networks with other providers rather than trying to expand their businesses on their own.

However, Watanabe warned that things could worsen for everyone as the government is expected to toughen the rules on users to rein in spending when it revises the program again in 2012. He said people must pressure the government not to make cuts and to improve the system.

"They should push (politicians) to improve the system," he said.
