You can make this in no time when you just need one more dish. It's an easy salad recipe that makes a great filling for hand-rolled sushi.
I like crab sticks, so I substituted them for potatoes in a potato salad.
I eyeballed the amount of mayonnaise (without measuring), so adjust to taste. The sugar is there to give it a subtle flavor. Be careful not to add too much; you only need just a little bit.
Enjoy Japanese food around the world.
