Today’s new lunchbox from Emart24 recreates an Osaka Dotonbori vibe: the Yakisoba & Karaage lunchbox. It’s the single-item entry among the several menus Emart24 rolled out under a “Japanese-style lunchbox” concept. Among the various yakisoba lunchboxes released so far, this one nails the reproduction and quality surprisingly well, and it turned out more edible than I expected. Convenience-store yakisoba, really? I know. So let’s take a look at what it’s like.

Osaka-Style Yakisoba & Karaage: Price and Highlights
A while back I reviewed an Osaka night-market-style Japanese assorted lunchbox, and its lineup of fried items and pickles was quietly solid. It had yakisoba too. So when I first bought this one, I assumed it was just that yakisoba with a bigger portion — but the short version is that the quality went up along with it. Haha. This one is priced at 4,500 won, which is on the cheap side even for a single-item convenience-store lunchbox.

Let’s take a quick look at the makeup. You can tell at a glance that among the yakisoba lunchboxes out so far, this one is quite something in both composition and quality. It’s a world apart from the dull brown (or black) noodles of a soy-and-yakisoba-sauce combo with a few sausage slices on top.

On top of that, this isn’t just plain yakisoba — it’s yakisoba & karaage. So there’s karaage laid over the noodles. Think of it as a side to eat alongside; it feels like about five or six pieces are included.

The yakisoba fillings seem to be green onion, carrot, cabbage, and bonito flakes, with mayo drizzled on top. Picture what you’d get at a specialist shop and it may seem like nothing, but for a convenience-store lunchbox it’s a quietly high-quality setup.

Now let’s dig in. First, you need to mix the warmed ingredients together well before eating, right? Since I’ve had trouble getting menus like this to mix well before, I ran it about 20 seconds past the recommended 1 minute 30 seconds in a 1000W microwave. As you can see, it mixes surprisingly well.

Copyright PAKOC https://pakoc.netThe Yakisoba and the Mayo
To start, the basic flavor is a pretty simple yakisoba taste with a bit of extra savory depth layered in. The fillings inside weren’t distracting at all — I’d call it a quietly enjoyable style of yakisoba. It goes down smoothly, and it didn’t feel too salty either.

Copyright PAKOC https://pakoc.netThe mayo drizzled on top was, to my taste, in just the right amount. It wasn’t too sour, and it didn’t push the salty savoriness of the yakisoba to an overpowering level. Sure, other convenience stores hand you a separate packet, but pre-drizzled works fine too. That said, before mixing, you might want to eyeball the amount and scoop a little off.

Copyright PAKOC https://pakoc.netThe Karaage Topping
The karaage was decent. Since this menu has no meat or sausage, effectively this is the main topping aside from the basic vegetables. The flavor itself isn’t much different from the karaage you’d see in a typical convenience-store lunchbox. But paired with the yakisoba sauce, it was quietly quite good.

Copyright PAKOC https://pakoc.netFinal Verdict
Personally, as a full meal, convenience-store yakisoba was a reasonably decent menu. What about you? Even though it’s not truly Japanese-style, among convenience-store lunchboxes it was a fitting pick as one where the teriyaki sauce isn’t too strong. If you’re curious, give it a try — it made for a solid single meal. For readers abroad, it’s an easy way to scratch a yakisoba craving on the cheap.
