The Star-Shaped Mayonnaise Nozzle Is Unique to Japan

The familiar, pretty "star shape" of Japanese mayonnaise nozzles is actually a very rare, Japan-exclusive cultural feature globally. Overseas, mayonnaise typically comes in jars you scoop out with a spoon or has a thin, round nozzle for squeezing. Japanese manufacturers developed it with the idea of "making salads look beautiful and dining tables more enjoyable," apparently as a form of Japanese hospitality (omotenashi).
