Japanese cucumber salad, or sunomono, is a refreshing side dish that turns thin sliced cucumbers into a crisp, tangy, and lightly sweet salad. The cucumbers are usually salted first to draw out extra moisture, then gently squeezed so they stay crunchy while absorbing the dressing. A simple sunomono dressing made with rice vinegar, sugar, soy sauce, salt, and sometimes dashi creates a clean balance of acidity, sweetness, and umami. Wakame seaweed, sesame seeds, crab stick, shrimp, ginger, or shiso can be added for more texture and flavor. The salad stays light and cool, making it perfect for balancing rich meals like fried chicken, gyoza, grilled fish, noodles, or rice bowls. The final sunomono is easy to prepare, quick to chill, and ideal as a Japanese home-style side dish for lunch, dinner, bento, or izakaya-style plates.
