What is oshizushi?
Oshizushi (a.k.a. oshi sushi—meaning “pressed sushi” or hakozushi / hako sushi—meaning “box sushi” in Osaka) is a traditional variation of sushi created during the 18th century in Osaka, Japan. It is pressed inside of a detachable wooden box known as an oshibako, oshizushihako, or hakozushigata. This creates a perfect rectangular or cubed shape. Known for its clean aesthetic, this block-shaped sushi can fit perfectly in a bento box and is often arranged in an eye catching pattern.
Pressed sushi can simply consist of fish and rice, or can be complexified with multiple layers of rice, seafood, and other sushi ingredients. One important characteristic of this type of sushi is that the fish is always cooked or cured. A specific version that uses mackerel is called battera, which means “box cured mackerel” and is derived from the Portuguese word bateria or “small boat.”A less common variation of pressed sushi uses a cylindrical oshibako to form the sushi into a puck-like shape.

How can I make it?
Anyone can easily make oshizushi. Just buy some sushi at your local Japanese restaurant or market and press it into an oshibako. However, if you want to create it in a more authentic manner, here is a simple process you can follow…
- 1 cup cooked sushi rice
- 1/2 cup imitation crab (can also use cooked shrimp, or cured salmon/mackerel – sliced lengthwise)
- optional layers:
- fresh cucumber (very thinly sliced)
- avocado (thinly sliced)
- rice vinegar (for coating wooden oshibako and dipping fingers)
- First, completely coat the inside of your oshibako with rice vinegar to prevent the ingredients from sticking.
- Line the bottom of the oshibako with a layer of imitation crab.
- Then, if you like, add layers of avocado, cucumber and nori. (Make sure to leave room for the rice.)
- Wet your fingers with rice vinegar. Cover the ingredients with an even layer of rice…all the way into the corners. Keep the rice below the rim of the box.
- Firmly press the ingredients together with the cover of the oshibako so they are tightly packed.
- Remove the pressed sushi from the oshibako and slice into pieces.
- Arrange the pieces on a plate or in a bento box with imitation crab side up. Enjoy!
