Kiseru (煙管, kiseru) is an old style Japanese smoking pipe. Kiseru were used for smoking a wide variety of substances, including tobacco, cannabis, and opium. It is typically made out of metal on the ends (the mouth piece and bowl), with a shaft typically made out of bamboo. Another distinct trait of a kiseru is that the bowl is much smaller than that of many western-style pipes, and if fitted with a fine-mesh metal screen, permits small servings at a low burning temperature.
