Wash and peel the carrots, discarding the outer skin.
Using a vegetable peeler, shave the carrots into long, thin ribbons. Place them in a mixing bowl.
In a separate bowl, whisk together sesame oil, rice wine vinegar, soy sauce, honey, and citrus juice if using.
Pour the dressing over the shaved carrots and toss to coat evenly.
Cover and refrigerate for at least 1 hour to chill and allow the flavors to blend.
Before serving, top with sesame seeds and chopped chives.
