@tezumitea: While incense might seem simple at first (light a stick and blow it out), like every traditional art, it comes with its own rich history and culture. For fifteen centuries, the crafted aromas of incense, or o-kō (御香), have permeated deep into the fabric of Japanese culture, used both formally and casually in a wide variety of occasions. The four types of incense you'll commonly encounter are: Senkō (線香 - Incense Sticks) Inkō (印香 - Pressed Incense) Nerikō (練香 - Kneaded Incense) Kōboku (香木 - Fragrant Woods)
