Food items lining the shelves of Japanese convenience stores, or “Konbini,” are known globally for their exceptionally high quality. Seven-Eleven Japan, a major Japanese convenience store chain, will begin sequentially renewing six popular Souzai (side dishes), including Japanese dining staples like “Grilled Silver Salmon” and “Chikuzenni,” starting Tuesday, February 3, 2026.
This renewal is not merely a change in packaging. Despite soaring raw material prices worldwide, they have achieved something surprising for some products: “increasing the portion size while keeping the price the same.” We explain the evolution of these Japanese “traditional side dishes” that support the diets of busy modern people.
Seven Premium Grilled Silver Salmon
The “Grilled Silver Salmon,” which boasts overwhelming popularity in the fish side dish category, has undergone a surprising evolution. The volume has increased while the price remains maintained. This is an indispensable item for traditional Japanese breakfasts and Bento boxes.
- Price: 368 yen (397.44 yen with tax)
- Release Date: Sequentially from Tuesday, February 3
- Sales Area: Nationwide in Japan
The Secret of “Volume Increase” Through Corporate Effort
In this era of rising prices, how is a “volume increase with price freeze” possible? The secret lies in increasing the size of the silver salmon sourced as raw material.
By sourcing larger-sized silver salmon and creating a system to use every part of the fish across various products, they have reduced costs and returned that value to consumers in the form of “increased volume.” This attitude of solving problems through business mechanisms rather than simple price hikes symbolizes the Japanese corporate spirit of ingenuity (Kaizen).
The Fragrance of Hand-Searing
The attention to detail goes beyond just quantity. They strictly select fatty raw ingredients and cut them into thick slices. For the finish, each piece is seared over an open flame (aburi) by hand. This creates a texture where the skin is crisp and savory, while the flesh is fluffy and soft. The savory aroma that spreads the moment you open the pack is of a quality you wouldn’t expect from a convenience store product.
Seven Premium Chikuzenni
“Chikuzenni” is a traditional Japanese home-cooked dish made by simmering chicken and vegetables in a sweet and savory sauce. This dish, which is time-consuming to make at home, has also been renewed.
- Price: 298 yen (321.84 yen with tax)
- Release Date: Sequentially from Tuesday, February 3
- Sales Area: Nationwide in Japan
Based on a broth (Dashi) infused with the umami of chicken, six types of ingredients including carrots, burdock root, lotus root, and shiitake mushrooms are simmered slowly. The flavors permeate the ingredients while retaining their individual textures. Considering the effort required to gather ingredients and cook this yourself, getting this authentic taste at this price is extremely reasonable.
Seven Premium Flavor-Infused Nikujaga
Particularly interesting in this renewal is the “Nikujaga” (meat and potato stew). Nikujaga is a representative Japanese home-cooked dish where meat and potatoes are simmered together, but the meat used actually differs by region. Seven-Eleven changes the specifications between Eastern and Western Japan to match local food cultures.
[Eastern Japan Area] Infused with the Umami of Pork
- Price: 298 yen (321.84 yen with tax)
- Release Date: Sequentially from Tuesday, February 3
- Sales Area: Eastern Japan (Kanto, Koshinetsu, Tohoku, Hokkaido)
In the Eastern Japan area, including Tokyo, Nikujaga using pork is common. The sweet and savory broth, with melted pork fat and umami, soaks firmly into the core of the potatoes. It is a taste beloved as the “taste of mom” in Japan.
[Western Japan Area] Beef Richness and Elegant Flavor
- Price: 318 yen (343.44 yen with tax)
- Release Date: Sequentially from Tuesday, February 10
- Sales Area: Western Japan (Kansai, Hokuriku, Chugoku, Shikoku, Kyushu, Okinawa)
On the other hand, in the Western Japan area, including Osaka and Kyoto, beef is used. Finished with an elegant Kansai-style seasoning, it leverages the unique richness and umami of beef. If you travel to Japan, it would be interesting to eat and compare the differences in taste by region.
Seven Premium Tonjiru with 8 Ingredients
“Tonjiru” is a Miso Soup containing pork and vegetables. It is perfect when you want to add one more dish to your meal.
- Price: 238 yen (257.04 yen with tax)
- Release Date: Sequentially from Tuesday, February 10
- Sales Area: Hokkaido, Tohoku, Kanto, Koshinetsu, Hokuriku, Shizuoka, Kinki, Chugoku, Shikoku, Kyushu
It uses as many as 8 types of ingredients, including root vegetables and pork. The flavor of the Dashi is rich, and it warms the body especially well in cold seasons. Having this with a Japanese Rice Ball (Onigiri) makes for a highly satisfying meal. It is also recommended when you are concerned about a lack of vegetables.
Seven Premium Domestic Pork Motsunikomi
“Motsunikomi” is a dish of simmered pork innards (hormone) and is a standard menu item at Japanese pubs (Izakaya).
- Price: 298 yen (321.84 yen with tax)
- Release Date: Sequentially from Tuesday, February 3
- Sales Area: Hokkaido, Tohoku, Kanto, Koshinetsu, Hokuriku, Shizuoka, Chugoku, Shikoku
Using domestic pork offal, it is simmered slowly until tender. The specific odor is suppressed, and the flavor of miso is firmly infused, resulting in a deep, rich taste. You can enjoy it with Japanese sake in your hotel room without going to an Izakaya.
Summary: Pursuing “No Compromise” Even with “Convenience”
In recent years, the need for “authentic taste” in meals eaten at home (Nakashoku) has been increasing in Japan. Responding to the wish of “being busy but wanting to eat delicious Japanese food,” Seven-Eleven is attempting to answer with quality that “exceeds the taste of home.”
From the Silver Salmon that challenged “price freeze and volume increase” amidst inflation, to the Nikujaga that respects regional characteristics, these products are packed with ingenuity to satisfy consumers. When you visit Japan, please stop by a nearby Seven-Eleven and experience the evolved Japanese Souzai (deli).
