Pat the salmon fillet dry with a paper towel and season both sides with sea salt and black pepper.
In a small glass jar, whisk together the tamari, rice vinegar, lime juice, and freshly grated ginger to create the glaze.
Heat the sesame oil in a non-stick skillet over medium-high heat until shimmering.
Place the salmon in the skillet skin-side up and sear for 4 to 5 minutes until a golden crust forms.
Flip the salmon and pour half of the citrus-tamari glaze over the fish, cooking for another 3 to 4 minutes until the salmon is flaky and the glaze has thickened.
Prepare the bowl by placing the cooked sushi rice at the base.
Top the rice with the glazed salmon, sliced cucumbers, thinly sliced radishes, and steamed edamame.
Drizzle the remaining glaze over the entire bowl before serving.
