01 - In a large mixing bowl, whisk together mochiko, cornstarch, soy sauce, sugar, eggs, garlic, ginger, green onions, sesame oil, salt, and black pepper until smooth and well combined.
02 - Add the chicken pieces to the marinade. Toss thoroughly to ensure each piece is evenly coated. Cover the bowl and refrigerate for at least 4 hours, or overnight for optimal flavor development.
03 - Fill a deep pot or large skillet with approximately 2 inches of vegetable oil. Heat the oil to 350°F, using a thermometer to verify temperature accuracy.
04 - Remove chicken pieces from the marinade, allowing excess to drip off. Fry in small batches, turning occasionally, until golden brown and cooked through, approximately 5–7 minutes per batch.
05 - Transfer fried chicken to a paper towel-lined plate to drain excess oil. Repeat with remaining chicken. Serve hot, garnished with additional green onions, sesame seeds, and lemon wedges if desired.
