A Japanese menu uses a vocabulary many guests have not mastered, maki, nigiri, sashimi, chirashi, donburi, gyoza, tataki. These are the correct terms, not fanciful names, but for a newcomer they are opaque words they will not take a chance on.
So they order the platter they know, or the six California rolls they have already had elsewhere. The dishes that take the most work, a well-built chirashi, a tataki, the chef's platter, stay on the menu because nobody knows what they look like.
Platters raise one more problem. A guest hesitating between three platters at different prices wants to see what is in them, and the list of pieces does not really tell them what they will find on the plate.
