Slice the English cucumber into 1/8-inch rounds and place in a colander for about 10 minutes to drain excess moisture.

In a large mixing bowl, layer the drained cucumber slices with the imitation crab and cubed avocado, folding gently.

In a separate bowl, mix the softened cream cheese, mayonnaise, soy sauce, and toasted sesame seeds until smooth.

Pour the dressing over the cucumber mixture and gently toss until everything is evenly coated.

Transfer to a serving bowl, sprinkle with additional sesame seeds, and serve immediately.
