Slice the daikon into 2cm wide half-moon pieces and peel the skin.

Pat the chicken wings dry with paper towels and season with salt and pepper.

Heat salad oil in a pressure cooker over medium heat. Add chicken wings and cook until browned, turning occasionally. Add daikon and stir until coated with oil.

Add all seasoning ingredients (sake, mirin, sugar, soy sauce, curry powder, and water) and mix well. Close the lid and cook on high heat until pressure builds, then reduce to low heat and cook for 15 minutes.
