As business opportunities loom with the deregulation of Japan's mammoth electricity market, Enron Corp. of the United States is preparing to launch comprehensive energy services in the world's second-largest economy.

"We see significant changes happening in Japan," he said. "We see changes happening in capital markets and in telecommunications. Also, there are other elements in important changes and perspectives on risks and risk management. That's very important to us."
