Steak is popular among many because of its savory flavor and fatty taste. Among steaks, many people are probably familiar with diced steak, a type of steak shaped like a cube. Saikoro steak, or “diced steak,” is a popular Japanese dish known for its bite-sized, flavorful cubes of beef. As the name suggests, diced steak is shaped like a cube. But why the dice shape? Read on to discover the appeal of Saikoro steak and why it has become a beloved part of Japanese cuisine!
What is Saikoro steak?

Saikoro steak (サイコロステーキ) is a type of diced beef steak in Japan, with “saikoro” meaning “dice” in Japanese. This dish consists of small, cube-shaped pieces of beef that are typically pan-seared or grilled, often served with a simple seasoning of salt, pepper, or soy-based sauce. Saikoro steak refers to steaks where chefs cut meat into cubes and grill them. There are two types: one where they reshape minced meat and another where they grill small pieces of meat. To make shaped meat, they solidify various parts of the animal, including minced innards, with sugar, eggs, soybeans, and beef fat. After freezing, they cut it into cubes, giving it the name “diced steak.”
How do locals cook Saikoro steak?
Although locals mainly use beef, you can also use pork and chicken. Locals generally cook this by grilling it in a frying pan or on a hot plate, and it is popular as a home-cooked dish because you can prepare it in a short time. Another feature of diced steak is that it is easy to purchase, as it is not limited to the part of the meat or its quality and may use processed or formed meat. Often simply seasoned with salt and pepper, and locals often eat this with soy sauce, butter sauce, garlic sauce, etc.
It is popular on izakaya (Japanese pub) menus and as part of home cooking, and because it is small but filling, it is also popular as a side dish for bento lunches or as a beer snack.
History

Diced steak was originally created as a way to reduce food waste by compressing and shaping meat trimmings that didn’t meet standards.
Its most likely origin can be traced back to “Bambolina” in Tokyo’s Nihonbashi-Kabutocho district. The story goes that the restaurant invented it as a quick and easy meal for busy stockbrokers in the area. Another theory is that it was first sold as “Stamina Steak” around 1970 at “Gyu-Tetsu” in Kurume City, Fukuoka Prefecture.
In addition, the “BIG SHEF” restaurant chain, which expanded throughout Japan during the country’s high economic growth period, is also credited with helping to popularize diced steak. Thanks to these factors, diced steak became popular as an affordable and easy-to-enjoy dish.
Why is saikoro steak shaped like a dice?

Saikoro steak is shaped like a cube for several reasons. First, its bite-sized form makes it easier to eat and cook, reducing the need for knives and ensuring even cooking. Second, it works well with processed meat, making shaped meat look more natural and improving texture. Lastly, it aligns with Japanese food culture, where small, easy-to-eat portions are preferred, especially in dishes like yakiniku and teppanyaki. These factors contribute to its popularity in Japan.
Things to note when grilling pre-formed meat

When grilling pre-formed diced steak, it’s best to cook vegetables separately or on the other half of the pan. Unlike regular meat, formed meat is made by binding various cuts with eggs or soybeans, so those with allergies should check labels carefully. Since it is processed, it must be fully cooked and cannot be eaten rare. If any red parts remain, heat them further. Formed meat also releases a lot of oil, so avoid adding extra oil and wipe off excess during cooking.
