Cut the boneless, skinless chicken thighs into uniform bite-sized pieces.

In a large bowl, combine gochujang, gochugaru, soy sauce, mirin, minced garlic, minced ginger, corn syrup, sesame oil, and black pepper to create the marinade.

Add the chicken pieces to the marinade and mix thoroughly, ensuring all chicken is well coated. Marinate for at least 30 minutes at room temperature, or up to 4 hours in the refrigerator for deeper flavor.
