Korean barbecue. Cook the thin slices of meat, tongue and vegetables at your table. And don’t forget the kimchi.

Witch woman. This term is applied derisively by the media to young women who sport artificial tans, dyed blonde hair, loose socks and lots of makeup. It's a term from a Japanese folk tale that describes an ogress who terrorizes villagers. Of course, the young women embrace the term, happy at the idea that they might actually scare their elders. The mecca for yamamba is Shibuya.

A light cotton robe, usually worn in summer. Blue and white yukata are standard issue at Japanese inns and hot springs resorts. Make sure the right side of the robe goes on the outside (or was it the left side?), so you won’t be mistaken for a corpse. Also, if you are new to Japan and a neighbor presents you with a yukata and tells you that everyone will be wearing one at the bon-odori festivities that night, be warned: You are definitely being set up. In fact, you may be the only one wearing a yukata, with the exception of a few elderly ladies, and you may look and feel like an idiot. Also, because you don’t really know how to wear one of these robes, you may inadvertently show way more flesh than a Japanese would – if they actually wore these robes. However, one good thing will come of all this: That night will be seared onto your memory as if it happened yesterday, not in 1986.

The fruit of the citron tree, sometimes called a Chinese lemon.
