Vinegar Cucumber Salad (Sunomono)
This refreshing Japanese vinegar cucumber salad, known as Sunomono, comes together in minutes with crisp cucumbers, rice vinegar, and a touch of sesame for a light, tangy side dish you'll crave all summer long.
The Crisp, Tangy Japanese Cucumber Salad You'll Make on Repeat
If you have ever sat down at a Japanese restaurant and found yourself quietly hoping for more of that little vinegared cucumber dish, you are in exactly the right place. This Vinegar Cucumber Salad, known in Japan as Sunomono (which simply means "vinegared things"), is one of the most refreshing, effortless side dishes in all of Japanese cuisine. It takes about ten minutes, requires no cooking, and delivers a bright, clean flavor that pairs beautifully with grilled fish, rice bowls, or really anything you happen to be making.
This is a traditional Japanese side salad that has been served in Japanese homes and restaurants for generations, and once you understand its simple logic, you will reach for it again and again.
Getting this right comes down to two things: using the proper cucumbers and choosing a good quality rice vinegar. Thin-skinned Japanese cucumbers or English cucumbers work best because their flesh is tender, their seeds are minimal, and they hold up beautifully to the dressing. A bottle of unseasoned rice vinegar and a light drizzle of toasted sesame oil are the ingredients that give this its signature flavor. Using the right tools, especially a mandoline slicer for thin, even cuts, makes the whole process faster and more satisfying.
What Makes Sunomono So Special
The beauty of this healthy Japanese cucumber salad is in its balance. The dressing is sweet, tangy, and just barely savory, never sharp or harsh. The cucumbers are salted first, which pulls out excess water and concentrates their flavor, giving you slices that are tender but still have a satisfying snap.
Sunomono is often served as a palate cleanser alongside richer dishes like teriyaki, miso soup, or sushi. It is light enough to eat in generous portions without any guilt, making it a go-to for anyone looking for a healthy Japanese salad dish that actually tastes exciting.
Chef's Tip: Do not skip the salting step. Letting the cucumbers sit with salt for 5 to 10 minutes before squeezing out the liquid is what keeps your salad from turning watery and bland within minutes of dressing it.
How to Build the Perfect Sunomono Dressing
The dressing for this Sunomono Cucumber Salad is a simple four-ingredient combination:
- Rice vinegar for that gentle, slightly sweet tang that defines the dish
- Sugar to soften the acidity and round out the flavor
- Soy sauce for a whisper of umami depth
- Sesame oil (optional but wonderful) for a warm, nutty finish
Whisk everything together until the sugar fully dissolves before adding your cucumbers. You can also add a small amount of freshly grated ginger if you enjoy a bit of warmth. It is a Sunomono Salad Recipe detail that feels subtle but makes the whole bowl taste more alive.
Choosing Your Cucumbers
For the most authentic Cucumber Japanese Recipe experience, look for Japanese cucumbers at an Asian grocery store. They are slender, nearly seedless, and have a thin skin that you do not need to peel. English cucumbers are an excellent substitute. Regular garden cucumbers work too, though you may want to scoop out the seeds and peel the thick skin before slicing.

Vinegar Cucumber Salad (Sunomono)
This refreshing Japanese vinegar cucumber salad, known as Sunomono, comes together in minutes with crisp cucumbers, rice vinegar, and a touch of sesame for a light, tangy side dish you'll crave all summer long.
Ingredients
- 2 Japanese or English cucumbers, thinly sliced into rounds
- 3 tbsp rice vinegar, unseasoned preferred
- 1 tbsp granulated sugar
- 1 tsp soy sauce, low-sodium recommended
- 1/2 tsp kosher salt, for drawing out moisture
- 1 tsp toasted sesame seeds, white or black, for garnish
- 1/2 tsp sesame oil, optional, for added depth
- 1/2 tsp fresh ginger, finely grated, optional
Instruction
Thinly slice the cucumbers into rounds, about 1/8 inch thick. A mandoline makes this quick and uniform.
Place the cucumber slices in a colander or large bowl, sprinkle with the kosher salt, and toss to coat. Let sit for 5 to 10 minutes to draw out excess moisture.
While the cucumbers rest, whisk together the rice vinegar, sugar, soy sauce, sesame oil, and grated ginger in a small bowl until the sugar fully dissolves.
Squeeze the salted cucumbers gently with your hands or press them with a clean kitchen towel to remove as much liquid as possible. Pat dry if needed.
Add the cucumbers to the dressing and toss well to coat every slice evenly.
Let the salad marinate for at least 5 minutes at room temperature, or refrigerate for up to 30 minutes for a more deeply flavored result.
Serve chilled or at room temperature, garnished with toasted sesame seeds.
Equipment
- Sharp knife or mandoline slicer
- Colander
