In Japan, there has long been a dish called “osozai” (side dishes).
“Osozai” are supposed to be eaten with rice, and the combination of these “osozai” helps to maintain a good nutritional balance.
I love “osozai” because they are an easy way to get vegetables, but living and working alone, it is difficult to take the time to cook them.
The savior in this situation is the “osozai” sold at convenience stores.
Convenience store “osozai” are sold in small portions and in a variety of varieties, so you can freely combine them to enrich your meals.
In this article, I will give an overview of convenience store “osozai”, their appeal points, recommended “osozai”, and ways to enjoy them, including my own experiences.

I hope that this article will spark your interest in convenience store “osozai”.
To review, what are “osozai” ?


“Osozai” are dishes that are served with the main meal (rice).
Originally, it meant daily side dishes that are homemade at home, but nowadays it also includes commercial side dishes sold at supermarkets and convenience stores, as well as home-delivered side dishes.
Each region has its own special characteristics, and a variety of dishes using local vegetables and seafood exist.
They are an indispensable part of the Japanese dining table and play an important role in supporting the eating habits of busy modern people.
What is the origin and history of “osozai”?
At that time, side dishes for weekday meals were called “sosai” in Edo and “banzai” in the Keihan region.
During the Edo period, a business selling boiled and seasoned dishes called “nimi-sei” also appeared, and this is believed to be the origin of commercially prepared side dishes.
There are many local dishes that make use of the food culture and ingredients of each region, and over time they have evolved from home-style delicacies to commercial products.
Until “osozai” were sold in convenience stores
Convenience stores first appeared in Japan in the 1970s. In the 1980s, they were called “late-night supermarkets” and began selling boxed lunches, rice balls, fried foods, and other items.
In 1979, 7-Eleven strengthened its system for supplying “osozai”, and since then, the company has enhanced its product lineup by using no preservatives and strict quality control.
Today, convenience store “osozai” have diversified and have become a part of Japanese food culture, used by men and women of all ages.



It is true that the development of convenience stores has made it easier for everyone to get hold of these products, and it is understandable that the variety of “osozai” in convenience stores has increased due to their capital power.
Three Attractions of “osozai”


I have summarized some of the attractions of “osozai” that I find appealing.
Easy access to a variety of traditional cuisines
Japanese convenience store “osozai” range from classic Japanese dishes such as meat and potatoes, grilled fish, and oden to Western dishes such as hamburgers and beef stew.
Seven-Eleven’s “Kin Series” and FamilyMart’s “Mom’s Shokudo” in particular are characterized by their ability to reproduce home cooking and allow visitors to experience Japanese food culture in a short time.
The convenience of microwave-safe containers and free chopsticks and spoons are also provided, making it easy for tourists to enjoy the food.
High quality ingredients and professional taste
Convenience store “osozai” are prepared in collaboration with specialty manufacturers and under the supervision of cookery researchers, so that dishes that would take time and effort at home are served at a high quality level.
For example, LAWSON’s fish dishes utilize local ingredients, and FamilyMart’s “charcoal-grilled yakitori” has sold a total of 100 million units.
The company’s cooking methods use fewer preservatives, and its nutritional balance has been improved, making it popular among health-conscious consumers.
Accessibility at any time of the day
With a 24-hour operation and a nationwide chain network, customers can easily purchase food at train stations and in town, even while sightseeing.
Not only does this solve the problem of eating at night or while traveling, but it also offers excellent cost performance, with many items discounted during time sales.
At stores with eat-in space, it is also convenient for foreigners to be able to eat hot immediately after purchase.



Considering the opening hours of convenience stores and the number of stores that are open, being able to eat delicious convenience store “osozai” anytime and anywhere is a high point.
