Not one set, but two. One for words of Japanese origin, the other for foreign words. Throw in some decorative English and it starts getting confusing. Most of the time I just hold up fingers and point. As you might imagine, mealtime can be a crapshoot.
Japan is famous for plastic displays of food in restaurant windows.
The problem is you must order inside the restaurant. The plastic food outside faces the street. One is to guide your waiter past other diners, through the restaurant and out the door to the street display and point to what you want. All the time you're hoping nobody thinks you're a terrorist taking a hostage and calls the Japanese Defense Forces or worse, the yakuza, the Japanese equivalent of the Mafia. I usually mangle the pronunciation, stressing syllables that are best left unstressed, pronouncing silent letters best left unspoken.
