This Japanese cucumber salad recipe with mirin transforms simple cucumbers into a crisp, refreshing dish with layers of umami and brightness. The secret lies in a quick-pickling technique that softens the cucumbers just enough while preserving their satisfying crunch.
I developed this recipe after discovering how mirin's subtle sweetness and acidity elevate the dish beyond basic vinegar salads.
The process is straightforward: thinly slice cucumbers, then toss them with a simple dressing of rice vinegar, sugar, and mirin. A sprinkle of toasted sesame seeds adds nutty depth, while optional garnishes like scallions or nori strips bring extra texture and visual appeal.
The result is a dish that's light yet satisfying, perfect for balancing richer meals or serving as a standalone vegetarian option.
What makes this salad special is its balance—crisp cucumbers, tangy dressing, and nutty sesame create harmony in every bite. The mirin not only enhances flavor but also helps tenderize the cucumbers without making them mushy.
Ready in just 15 minutes, this recipe is ideal for warm weather or as a refreshing side to sushi, grilled fish, or even a simple bowl of rice.
For best results, let the salad sit for 10 minutes before serving to allow flavors to meld. The dressing will cling to the cucumbers, creating pockets of umami and sweetness that make each bite irresistible.
Whether you're hosting a dinner or packing a lunch, this salad delivers restaurant-quality refreshment with minimal effort.
Ingredients for japanese cucumber salad recipe mirin
Eleven simple ingredients transform cucumbers into a restaurant-quality dish with umami depth and refreshing crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Japanese Cucumbers 🥒 | 2 lb | Thinly sliced lengthwise, seeds removed |
| White Rice Vinegar 🍶 | ¼ cup | Mild and aromatic preferred |
| Mirin 🍶 | ¼ cup | Sweet cooking mirin, not seasoning mirin |
| Granulated Sugar 🍚 | 2 tbsp | Fine grain for quick dissolving |
| Toasted Sesame Seeds 🌰 | 2 tbsp | Lightly toasted for nutty aroma |
| Fresh Scallions 🧅 | 3 whole | Thinly sliced, green parts separated |
| Nori Strips 🍣 | ¼ oz | Thinly sliced, optional garnish |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain for delicate seasoning |

The Japanese cucumbers are non-negotiable for this recipe—thin-skinned varieties like Hokkaido or English cucumbers work best, but regular cucumbers can substitute if sliced extra thin. For the mirin, Kikkoman or Marukome brands are reliable choices, available at most Asian markets or well-stocked grocery stores. If you can't find authentic mirin, substitute with 1 part sugar to 2 parts rice vinegar, though the flavor won't be identical. The sesame seeds should be toasted in a dry pan for just 30 seconds until fragrant—no oil needed—as this enhances their nutty aroma without overpowering the delicate dressing. For the cucumbers, remove the seeds with a spoon to prevent bitterness, then slice into even 1/8-inch strips for consistent texture.
No mirin? Rice vinegar plus sugar works, though the dish loses some of its signature umami sweetness. The sugar can be swapped for agave nectar if you prefer a more liquid sweetener, but granulated dissolves cleanly. For the scallions, separate the green tops from the whites—the greens add bright flavor, while the whites provide subtle crunch. If you're avoiding gluten, ensure your nori strips are certified gluten-free, as some brands may contain wheat-based additives. The sesame oil adds depth, but if you're sensitive to its strong flavor, reduce to 0.25 tsp or omit entirely. For a spicier kick, increase the red pepper flakes to 0.5 tsp, but remember this is optional—traditional versions often omit heat entirely.
This salad keeps best when refrigerated in an airtight container for up to 3 days, though the cucumbers may soften slightly after 24 hours. For longer storage, drain the dressing before refrigerating and toss the cucumbers with a fresh dressing when ready to serve. The sesame seeds and nori can be added fresh just before serving to maintain their crispness. If prepping ahead, store the dressing and cucumbers separately—combine them only 10 minutes before serving to preserve the perfect crunch. The dish pairs beautifully with grilled fish, sushi, or steamed rice, and the flavors actually improve slightly after sitting, as the cucumbers absorb the dressing more fully.

Step-by-step instructions for Japanese cucumber salad with mirin
This refreshing salad balances crisp cucumbers with umami-rich mirin and delicate seasoning.
Prepare the Cucumbers
Begin by rinsing the 2 lb Japanese cucumbers under cold water to remove any dirt or sand from the skin. Pat them completely dry with paper towels—this ensures the vinegar dressing clings properly rather than creating a watery salad.
Using a sharp chef's knife, slice the cucumbers lengthwise into ¼-inch thick strips. Remove the seeds by gently scraping with your fingernail or a spoon, then slice the flesh crosswise into ½-inch pieces. The seeds can make the salad bitter, so thorough removal is key. Arrange the prepared cucumbers in a colander and set aside.
Create the Dressing
In a small bowl, whisk together the 0.25 cup white rice vinegar, 0.25 cup mirin, and 2 tbsp granulated sugar until the sugar dissolves completely. The sugar should fully integrate, creating a smooth, slightly sweet liquid. If any grains remain, stir over warm water for 10 seconds to help dissolve.
Add the 0.5 tsp Diamond Crystal kosher salt, 1 tsp extra-virgin olive oil, and 0.5 tsp sesame oil to the mixture. Stir gently to combine—avoid vigorous mixing to prevent emulsifying the oils prematurely. Taste the dressing and adjust the sweetness or acidity if needed, though the original measurements should balance perfectly.
Combine and Marinate
Pour the dressing over the cucumbers in the colander and toss gently to coat evenly. Let the salad sit at room temperature for 10 minutes to allow the flavors to meld. This brief resting period ensures the cucumbers absorb the dressing without becoming soggy.
While the cucumbers marinate, thinly slice the 3 whole fresh scallions, separating the green and white parts. Sprinkle the white portions over the cucumbers first, followed by the greens. Add the 0.25 oz nori strips and 0.25 tsp red pepper flakes (if using) and toss lightly to distribute evenly. Avoid overmixing to preserve the cucumbers' crisp texture.
Finish and Serve
Transfer the salad to a serving platter and sprinkle the 2 tbsp toasted sesame seeds evenly over the top. The seeds should be distributed in small clusters rather than a uniform layer for visual appeal. Let the salad rest for 5 minutes before serving to allow the flavors to fully develop.
Serve immediately while the cucumbers remain crisp. The salad should have a bright, tangy dressing with a subtle sweetness from the mirin and a nutty depth from the sesame seeds. For best results, consume within 2 hours to maintain optimal texture.
Pro Tips For Making Japanese Cucumber Salad Recipe Mirin
- Slice Thin, Soak Fast: Japanese cucumbers are tender—slice them ⅛-inch thick or thinner, then toss immediately in ice water for 10 minutes. This stops bitterness and keeps them crisp. I used to skip soaking, and the salad always tasted mealy by the second bite.
- Toast Seeds Fresh: Buy sesame seeds raw and toast them yourself in a dry pan over medium heat for 2–3 minutes, shaking constantly. Store-bought toasted seeds taste stale after a week, and this takes 60 seconds. Worth it—they’ll smell amazing and add real depth.
- Balance Vinegar and Sugar: Start with 1:1 ratio of rice vinegar to sugar (e.g., 2 tbsp each), then taste. If the dressing tastes harsh, add a splash of mirin to mellow it. I learned this after making a batch that tasted like a science experiment—now I adjust as I go.
- Chill Before Serving: Let the salad sit uncovered in the fridge for at least 30 minutes after dressing. The flavors meld better, and the cucumbers absorb the liquid without turning soggy. I used to serve it right away, and it always felt flat—now it’s bright and cohesive.
Creative variations of these flavors
Spicy Kick Version
Add 1 tsp gochugaru (Korean red pepper flakes) to the dressing for a fiery twist that complements the mirin’s sweetness. I like to toast the flakes in a dry pan for 30 seconds to deepen their smoky aroma before mixing.
For a milder heat, reduce to ½ tsp—this version still packs a punch without overwhelming the delicate cucumbers. 🌶️
Herb-Infused Twist
Swap the scallions for 1 tbsp finely chopped mint and 1 tbsp cilantro, then add 1 tsp minced shallot to the dressing. This Thai-inspired variation keeps the mirin’s umami but introduces bright, herbal notes. Garnish with crushed peanuts for texture—just 1 tbsp adds crunch without overpowering.
Protein-Packed Upgrade
Toss in ½ cup cooked edamame or ¼ cup thinly sliced avocado for a vegan protein boost. For a non-vegetarian option, add 2 oz thinly sliced smoked salmon or 2 tbsp furikake (Japanese seasoning) for a savory depth. The protein pairs beautifully with the crisp cucumbers and tangy dressing.
Summer Berry Fusion
Add ½ cup diced strawberries or blueberries to the salad for a sweet-tart contrast. Reduce the sugar in the dressing to 1 tbsp to balance the fruit’s natural sweetness.
This version works beautifully as a light dessert or refreshing side for grilled meats. The berries soften slightly after 10 minutes, absorbing the dressing perfectly.
Smoky Sesame Crunch
Replace toasted sesame seeds with 1 tbsp black sesame seeds (toasted) for a nutty, earthy depth. Add ½ tsp smoked paprika to the dressing for a subtle smokiness.
This variation feels like a cross between Japanese and Mexican flavors—perfect for a fusion dinner. Serve with warm tortilla chips on the side for scooping.
Winter Warmth Adaptation
Add ½ tsp grated fresh ginger and 1 tsp honey to the dressing for a warming twist. Top with thinly sliced persimmons or mandarin orange segments for a festive touch.
This version is ideal for holiday gatherings—the ginger and honey create a cozy contrast to the crisp cucumbers. 🍊

Frequently asked questions
Can I use regular cucumbers instead of Japanese cucumbers?
Yes, but you'll need to adjust the preparation. Regular cucumbers have thicker skins and more seeds, so slice them extra thin (⅛-inch) and remove all seeds thoroughly. For best texture, soak them in cold water for 10 minutes before slicing to reduce bitterness. Japanese cucumbers stay crisp longer due to their thin skin and fewer seeds.
What's the difference between mirin and sweet rice wine?
Mirin is a traditional Japanese cooking wine with 14-15% alcohol and added sugar, while sweet rice wine (like awamori) is fermented without sugar. For this salad, use authentic mirin (like Kikkoman) for proper sweetness and umami. Substitutes like 1 part sugar + 2 parts rice vinegar work in a pinch, but the flavor won't be identical.
How do I prevent the cucumbers from getting soggy?
Keep the salad chilled until serving and combine the dressing only 10 minutes before eating. Use a colander to drain excess moisture after tossing, and avoid overmixing. For extra crispness, add 1 tsp cornstarch to the dressing—it helps maintain texture. Serve immediately after plating for the best crunch.
Can I make this salad ahead of time?
Prepare the cucumbers and dressing separately, then combine just before serving. Store cucumbers in an airtight container with paper towels to absorb moisture for up to 24 hours. Keep the dressing refrigerated and mix when ready. The flavors meld better when fresh, but the texture won't be as crisp after sitting.
What's the best way to toast sesame seeds?
Use a dry skillet over medium-low heat and toast 2 tbsp sesame seeds for 1-2 minutes, stirring constantly until fragrant. They're done when they turn golden and smell nutty—don't walk away! Let them cool completely before sprinkling on the salad to prevent burning. Store any extras in an airtight container for up to 2 weeks.
