Cable TV operator Jupiter Telecommunications Co. announced Wednesday it is launching a flat-rate on-demand TV service allowing subscribers in Japan to watch American programs created by U.S.-based Warner Bros. Entertainment Inc.

The programming will include "Eleventh Hour," "Southland," "Gossip Girl," "Friends" and "ER."

"We will try a new business model in the pay multi-TV-channel market," Hiroyuki Nakatani, senior corporate officer of the Tokyo-based company better known as J:Com, said at a news conference.

J:Com provides cable TV services in major cities and their surrounding areas.

The Warner service, which starts July 15, will be part of three basic plans that include other cable channels. The monthly rates will run from ¥4,980 to ¥5,439.

The company's main customers have been family households, but the new on-demand service will also target young people and single households, Nakatani said.
