Bring a large pot of salted water to a rolling boil. Add the shrimp and poach for 2 to 3 minutes until opaque and curled into a C-shape.
Immediately transfer shrimp to an ice bath to arrest the cooking process. Once chilled, drain thoroughly and pat dry.
In a medium mixing bowl, whisk together the soy sauce, sesame oil, rice vinegar, grated ginger, and minced garlic.
Incorporate the chilled shrimp into the marinade and refrigerate for 10 minutes to allow flavor absorption.
Divide the cooked sushi rice evenly between two serving bowls.
Arrange the marinated shrimp, avocado slices, cucumber, edamame, and julienned carrots in distinct sections on top of the rice.
Drizzle any remaining marinade from the shrimp bowl over the vegetables.
Garnish the assembled bowls with sesame seeds and sliced green onions before serving.
