Slice the cucumbers into thin rounds or half-moons. Place in a colander and toss with the salt. Let sit for 10 minutes to draw out excess water.
After 10 minutes, rinse the cucumbers briefly under cold water and gently squeeze out as much liquid as possible. Pat dry with a clean towel.
In a medium bowl, whisk together the minced garlic, soy sauce, rice vinegar, sesame oil, gochugaru, and sugar until the sugar dissolves.
Add the drained cucumbers to the bowl and toss well to coat with the dressing.
Fold in the toasted sesame seeds and fresh herbs. Serve immediately or refrigerate for up to 30 minutes to let flavors meld.
