"By farming salmon locally in Japan, we are increasing Japan's self-sufficiency rate," Proximar Chief Executive Joachim Nielsen told reporters. Faced with volatile fossil fuel markets and searching for stable revenue streams, Marubeni and its rivals have been diversifying into the food business, where demand is set to grow alongside the rising world population. Mitsubishi owns Norway-based Cermaq, one of the world's leading salmon farmers, and is exploring salmon land farming in Japan. At the same time, Mitsui & Co. is a shareholder of the world's biggest shrimp farming and processing companies in Ecuador and Vietnam. Mitsui expects profits in its lifestyle unit, which includes food, to exceed those earned by chemicals this fiscal year.
