Iwakuni-zushi: A Pressed Sushi Made for Sharing

Iwakuni-zushi is a pressed sushi (oshi-zushi) from Yamaguchi's Iwakuni area, made by layering seasoned rice with ingredients like egg, fish, shiitake mushroom, and vegetables in a large wooden mold, sometimes several layers thick, then pressing it firmly before cutting it into squares. Its origins are linked to preparations for feeding large groups, whether troops or festival crowds, in the feudal era, which explains both its scale and its sturdy, transportable form.

Unlike everyday sushi, Iwakuni-zushi is traditionally made for festivals, celebrations, and family gatherings rather than sold as routine takeout, though some shops and supermarkets do sell smaller portions year-round. Its dense, multi-layered structure means each square delivers a mix of flavors and textures in one bite, closer to a savory layered cake than to nigiri sushi. If you want to try it outside a festival, checking a local grocery store's prepared food section is a reasonable bet.
