Rinse the sushi rice until the water runs clear. Cook according to package instructions (usually 1:1 rice to water). Fluff and set aside to cool slightly, seasoning with a pinch of salt or a splash of rice vinegar if desired.
Whisk together soy sauce, sesame oil, rice vinegar, honey, grated ginger, and Sriracha. Taste and adjust seasoning.
Gently toss cubed salmon with about 2 tablespoons of the marinade. Refrigerate for 10 minutes to let flavors meld. Reserve remaining marinade to drizzle later.
Slice avocado, dice cucumber, shred carrot, and chop green onions. Steam edamame if using.
Divide rice between bowls. Top with marinated salmon, avocado, cucumber, carrot, and green onions. Drizzle reserved marinade over the top, sprinkle with sesame seeds and nori.
Squeeze lime if desired and serve immediately to enjoy the contrast of textures and fresh flavors.
Notes
For a safer raw option, freeze salmon for 48–72 hours before thawing and using.
To make ahead, store rice and marinated salmon separately for up to 2 days.
Swap rice for mixed greens for a low-carb version; warm rice and cool toppings create a pleasing contrast.
