What Is Seaweed Rice?

Wakame Gohan is a Japanese mixed rice dish in which cooked rice is combined with rehydrated wakame seaweed and mild seasonings. Unlike heavily seasoned rice dishes, it highlights the fresh, ocean-like flavor of wakame while allowing the rice to remain soft and fragrant.

Although it can be enjoyed year-round, Wakame Gohan is especially popular as part of everyday home-cooked meals and packed lunches.
