Slice the cucumbers thinly, about 3 mm thick. Peel if the skin is tough.
Julienne the carrots into thin matchsticks, or shred them with a box grater.
Whisk together the rice vinegar, sesame oil, soy sauce, honey, and minced garlic in a small bowl until smooth.
Combine the cucumbers and carrots in a large bowl, pour the dressing over them, and toss gently to coat.
Taste and adjust seasoning with salt and black pepper as needed.
Top with sesame seeds and fresh herbs. Serve immediately or chill for 15 minutes before serving.
