Marubeni on Friday began selling salmon from a farm operated near Mount Fuji by its Norwegian partner, marking another step in Japanese commodity trading houses' expansion into the food business.

Wild and sea-farmed salmon is one of the areas Marubeni and its rivals have been targeting in what is a growth market in Japan, which aims to raise the share of locally sourced seafood it consumes to 94% in 2033 from 54% now.

Marubeni has a stake in Danish Salmon, one of the world's top land-farmed salmon producers, which focuses on the European market, and now is handling sales of Atlantic salmon for Norway's Proximar Seafood AS, which operates Japan's first land farm.
