Today’s “delicious” becomes tomorrow’s “joy.”

Social issues we aspire to solve in food
Have you ever had the experience of wanting a particular bento meal box, only to find it sold out?
Popular bento meal boxes sell out quickly. But Conversely, there are also many bento meal boxes that are discarded even though they’re still edible, simply because they have a short shelf life. This is the food loss and waste that has become a problem for society as a whole.
Warabeya’s solution!
Use-by Date
Up to Approximately Doubled
Ready for you the moment you feel like eating.
To that end, we advanced the use of chilled temperature control to prevent spoilage and technologies to maintain freshness.
And while maintaining the same great flavor, we have successfully extended the shelf life to approximately twice as long (about two days)* as before. Increased time of shelves means more opportunities for customers to pick up our products, ultimately leading to reduced food loss and waste.

Fluffy eggs and the rich umami of bonito broth. This classic taste has evolved through a combination of innovations—including the container itself.
Social issues we aspire to solve in food
For many years, we have continuously improved our bento packaging to reduce CO₂ emissions, including replacing the main container with paper. Yet one challenge remained: the inner tray that separates the dashi-soaked pork cutlet from the rice. While paper containers helped cut CO₂ emissions, plastic was still needed for the inner tray.
Warabeya’s solution!
CO₂ Reduction
Equivalent to
58,000 Trays
*Estimate based on actual sales for the fiscal year ended February 2025.
This inner tray actually incorporates plant-derived materials as part of its raw materials.
By reducing the use of petroleum-based plastic, we have taken another step toward lowering CO₂ emissions.
Combining paper with plant-based materials, we are advancing a more sustainable future.
That is our answer.

The Botan Pepper from Nagano Prefecture looks just like a bell pepper and features a tangy, spicy taste that is addictive. We have captured the flavors of this region in our rice balls.
Social issues we aspire to solve in food
The Botan Pepper is a valued traditional vegetable that has long been adored in Nagano Prefecture.
However, due to limited cultivation environments, awareness of this pepper has remained low, and the number of producers has been decreasing year by year. They’re delicious—but there are few farmers one left to carry them on. If this continues, this local flavor will become a lost taste. We faced such a crisis.

What we can do is deliver the deliciousness of this Botan Pepper to everyone in the community. When you pick it up and say, “This is delicious!” it encourages the producers and becomes your support for continuing to grow traditional vegetables. Working together with local students, we will pass on the region’s food culture to future generations. That is our approach.
