Japanese cuisine is known for its delicate flavors, fresh ingredients, and aesthetically pleasing presentations. One such dish that embodies these qualities is the Sunomono, a Japanese cucumber salad that is often served as a side dish or appetizer. This healthy and refreshing salad is an excellent complement to a variety of Japanese meals, including sushi and other seafood dishes. It is simple to prepare, light on the palate, and incredibly versatile. In this article, we will explore the ingredients, preparation methods, variations, and benefits of the Japanese cucumber salad, also known as Sunomono.
What is Sunomono?
Sunomono (酢の物) is a Japanese term that refers to vinegared dishes, with su meaning vinegar and mono meaning thing or dish. The cucumber salad is typically made with thinly sliced cucumbers, seasoned with vinegar-based dressing, and often paired with seafood, such as shrimp, crab, or octopus. While it is traditionally served as an appetizer, it can also function as a side dish to complement a variety of meals, especially in sushi restaurants. Sunomono has become a favorite in Japanese cuisine because of its refreshing, tangy flavor and the way it balances the richness of other dishes.
The star ingredient of Sunomono is, of course, the cucumber. Its crisp, refreshing texture pairs wonderfully with the sweet and tart vinegar dressing, making it a favorite in Japanese restaurants worldwide. In fact, you may have seen this cucumber salad served alongside sushi rolls at your favorite sushi restaurant. It’s often referred to as the Sushi Restaurant Cucumber Salad, where it complements the rich flavors of sushi and sashimi.

Ingredients for Japanese Cucumber Salad
The beauty of Sunomono lies in its simplicity. The ingredients required for this dish are easy to find and usually consist of:
- Cucumbers: Japanese cucumbers are the most traditional choice for this salad, as they are thin-skinned, crunchy, and have fewer seeds than their Western counterparts. If Japanese cucumbers are unavailable, you can substitute them with English cucumbers or other varieties, but be sure to peel them if the skin is too thick.
- Rice Vinegar: This is a key ingredient in the vinegar-based dressing. It imparts a mild, slightly sweet tang that is characteristic of Japanese cuisine.
- Sugar: A small amount of sugar helps balance the acidity of the vinegar and enhances the overall flavor of the salad.
- Salt: A pinch of salt helps draw out the moisture from the cucumbers, ensuring they maintain their crisp texture.
- Sesame Seeds: Toasted sesame seeds add a nutty flavor and a nice crunch to the salad.
- Optional Garnishes: Some variations of Sunomono include thinly sliced seaweed, such as wakame, or other vegetables like radishes or carrots for added color and texture. These add complexity to the salad while maintaining its freshness.
The Classic Sunomono Recipe
Here’s a simple and classic recipe for making Sunomono:
Ingredients:
- 2 medium-sized Japanese cucumbers (or 1 large English cucumber)
- 2 tablespoons rice vinegar
- 1 tablespoon sugar
- 1 teaspoon salt
- 1 tablespoon toasted sesame seeds
- Optional: 1 tablespoon thinly sliced wakame (seaweed) or any other preferred garnish

Instructions:
- Prepare the Cucumbers: Wash the cucumbers thoroughly. Cut off the ends and slice them thinly using a mandolin or a sharp knife. You can slice them into rounds or half-moons, depending on your preference. Place the slices into a bowl and sprinkle them with salt. Let the cucumbers sit for about 10-15 minutes to allow the salt to draw out excess water and soften them slightly.
- Make the Dressing: In a separate bowl, mix the rice vinegar and sugar until the sugar is dissolved. Taste the dressing and adjust the sugar or vinegar to your liking.
- Combine and Toss: After the cucumbers have softened, gently squeeze out any excess water. Add the cucumbers to the dressing and toss well to coat them evenly.
- Garnish and Serve: Sprinkle the toasted sesame seeds over the top and garnish with seaweed or any other desired toppings. Serve immediately or refrigerate for about 30 minutes to allow the flavors to meld.
This simple recipe serves as the foundation for many variations of Sunomono. It’s a delightful and light salad that works well as a Cucumber Side Salad for lunch or dinner. Plus, it can be made in just a few minutes, making it a great addition to any meal.
Variations of Sunomono
While the basic Sunomono recipe is delicious on its own, there are many ways to customize it to suit your tastes. Here are some popular variations:
- Kiwi Cucumber Salad: To give the salad a unique twist, you can incorporate kiwi fruit. The sweetness of the kiwi balances the tanginess of the vinegar dressing, adding a tropical flavor to the salad. Simply peel and slice a ripe kiwi and add it to the cucumber slices. This variation is not only delicious but also colorful and full of vitamins.
- Japanese Marinated Cucumbers: For a deeper flavor, you can marinate the cucumbers for a longer period of time. Simply let the cucumber slices sit in the vinegar dressing for 30 minutes to an hour before serving. This allows the cucumbers to absorb the flavors and enhances their tangy profile.
- Sushi Restaurant Cucumber Salad with Seafood: For a heartier version of Sunomono, consider adding seafood like shrimp, crab, or octopus. Thinly slice the seafood and mix it with the cucumbers and dressing. This is a common feature in sushi restaurants, where it serves as a refreshing appetizer before the main course.
- Japanese Green Salad: While Sunomono is often just cucumber-based, you can create a more substantial salad by adding other vegetables. Try incorporating thinly sliced radishes, carrots, or even a few leafy greens like lettuce or spinach to create a Japanese Green Salad. The variety of textures and flavors adds depth to the dish while maintaining its lightness.
- Japanese Cabbage Side Dish: If you enjoy cabbage, you can also create a variation of Sunomono by adding shredded cabbage to the mix. The cabbage adds a crunchy texture and a slight sweetness that complements the cucumbers and vinegar dressing beautifully. This makes for a perfect Japanese Veggie Side Dish.
