Gather all ingredients needed for the salad in a mixing bowl.

In a medium mixing bowl, combine sugar, sesame seeds, garlic, and green onion. Add soy sauce, rice vinegar, chili oil, and sesame oil. Whisk until smooth.

Cut both ends of the cucumbers and slice diagonally using chopsticks for accordion-cut technique.

Place cut cucumbers in a bowl, sprinkle with salt, and massage to release moisture. Let them sit for 8-10 minutes.

Rinse cucumbers under cold water to remove excess salt, drain in a colander, and dry completely.

In a large bowl, combine cucumbers with dressing and toss until evenly coated.

Let the salad marinate in the refrigerator for at least 10 minutes before serving.
