1. If you are using Japanese cucumber, this step called itazuri is necessary. Wash 2 Japanese or Persian cucumbers and sprinkle them with Diamond Crystal kosher salt. With both hands, rub the cucumber against the cutting board. It removes the pointy bumps on the cucumber and helps absorb the dressing.
2. Alternate peeling ½-inch (1.3-cm) strips of skin lengthwise and leaving strips of skin intact. With this striped pattern, the cucumber slices have some decorative dark green accents and a little bit of extra crunchiness. Cut the cucumbers into thin slices, about ⅛-inch (3 mm) thickness (or even thinner).
3. Sprinkle with Diamond Crystal kosher salt and rub the cucumber slices gently with your hands. Let it rest for 5 minutes or so until they are wilted. Then, quickly rinse the cucumber slices under cold water. Squeeze the cucumber to get rid of the water.
4. Put 1 Tbsp dried wakame seaweed in a small bowl and soak in water for 10 minutes to rehydrate. Squeeze dry to get rid of the water.
5. Cut 4 real or imitation crabmeat sticks in half and shred it with your hands. 
6. In a small saucepan, combine the dressing ingredients: 3 Tbsp rice vinegar (unseasoned), 1 Tbsp sugar, ½ Tbsp soy sauce, ¼ tsp Diamond Crystal kosher salt, and 2 Tbsp dashi (Japanese soup stock). Mix well. Then, heat until the sugar is dissolved. Remove from the heat and set aside.
7. In a large bowl, combine the cucumber, wakame, and shredded crab sticks. Pour the dressing on top and mix together. Sprinkle toasted white sesame seeds and enjoy the salad at room temperature or chilled.

1. You can keep the leftovers in an airtight container and store in the refrigerator for a day. However, the crispness of the cucumbers will be lost and the seasoning may become diluted due to moisture released from the cucumber.
