Mince the shrimp in a food processor or finely chop with a sharp knife, then transfer to a large mixing bowl.
Add the peas, corn, carrot, spring onion, egg, cornflour, salt and white pepper. Mix until well combined.
Using slightly damp or gloved hands, scoop about 2 tablespoons of the mixture, roll into a ball, then gently flatten into a patty. Repeat with the remaining mixture.
Arrange the shrimp cakes in a single layer in the air fryer basket and lightly spray the tops with oil.
Air fry at 180°C (350°F) for 10–12 minutes, or until the shrimp cakes are cooked through and lightly golden.
While the shrimp cakes are cooking, stir together the Kewpie mayonnaise and wasabi paste until smooth.
Serve the shrimp cakes immediately with the wasabi mayo dipping sauce.
