Does this Japanese salad dressing have a name?

When I make nikumaki, I make a salad dressing/dipping sauce of mayonnaise, soy sauce, rice wine vinegar, and mirin. I never seem to remember to put sesame oil in, but that’s OK. It tastes good as it is. We use it on the Spring-greens salad as a dressing, and as a dipping sauce for the nikumaki.

Does this dressing have a Japanese name?

If you remembered the sesame oil I guess it would be a Goma dressing. Goma just means sesame and any dressing with the ingredients you list and any form of sesame - oil, white seeds or black seeds would be a goma dressing.

A lot of the reason Japanese cooking is such is fun is that there are so few basic ingredients.
