Japanese potato salad, also known as potesara, is a creamy and comforting side dish made with tender potatoes, crunchy vegetables, and rich Japanese mayonnaise. The potatoes are boiled until soft, lightly mashed, then mixed with thin cucumber, carrot, onion, ham, corn, boiled egg, or green peas for color and texture. Japanese mayo gives the salad its smooth, slightly tangy flavor, while rice vinegar, salt, pepper, mustard, or a small amount of sugar can make the taste more balanced. The soft potatoes create a creamy base, and the vegetables add a fresh bite so the salad stays light enough to enjoy with many meals. The final potesara is easy to prepare and works well for bento boxes, sandwiches, fried chicken, grilled meat, rice bowls, or izakaya-style small plates at home.
