Cucumber Sunomono Salad With Crab is a refreshing Japanese side dish built on salted, squeezed cucumber slices tossed with rehydrated wakame and a balanced rice vinegar dressing, topped with crab and sesame. Its standout trait is the technique of salting and squeezing the cucumbers until translucent, which concentrates flavor and creates the signature tender-crisp texture.

Use a mandoline slicer or a sharp knife to thinly slice 260 grams Japanese cucumbers into a medium bowl. Add 1/4 teaspoon salt and toss to coat evenly. Let it rest for 5-10 minutes.
Rehydrate 45 grams wakame according to the package directions and chop it into bite-size pieces.
Whisk together 2 tablespoons rice vinegar, 1 tablespoon evaporated cane sugar, and 1/4 teaspoon salt in a non-reactive bowl until the solids are dissolved.
Once the cucumber slices start sweating liquid, massage them with your hand to speed up the process. When they become translucent, they are ready to be squeezed. Grab them with your hands and squeeze as much water as possible.
Add the squeezed cucumber and wakame to the vinegar mixture and toss everything together to coat.
Serve the kani sunomono in small kobachi bowls, garnish with 4 pieces crab meat (or your choice of seafood), and sprinkle with 1 teaspoon toasted sesame seeds.
Store the squeezed cucumber and wakame separately from the vinegar dressing in airtight containers for up to 1 day; combine and add crab garnish just before serving.
mandoline slicer (or sharp knife)
Yes, you can prepare the components separately and assemble just before serving. Store the squeezed cucumber and wakame in an airtight container for up to 1 day; keep the vinegar dressing separate and combine when ready to serve to prevent sogginess.
Squeezing removes excess water after the salt draws it out, preventing a watery final dish. This step also makes the cucumber translucent and allows the vinegar dressing to coat and flavor it evenly.
Cooked shrimp, octopus, imitation crab, or even thinly sliced cooked fish work well. You can also omit the protein entirely for a vegetarian version and increase the wakame for more substance.
Japanese cucumbers are thinner, have fewer seeds, and a thinner skin that doesn't require peeling, making them ideal. English or hothouse cucumbers work as a substitute but may require seeding and peeling to avoid bitterness and excess water.
Follow package directions, which typically involve soaking in cool water for 5–10 minutes until tender. Drain and squeeze out excess water before chopping and adding to the salad.
