Sake is traditionally drunk from small cups called "choko" or "o-choko" () and poured into the choko from ceramic flasks called "tokkuri". This is very common for hot sake, where the flask is heated in hot water and the small cups ensure that the sake does not get cold in the cup, but may also be used for chilled sake. Traditionally one does not pour one's own drink, which is known as "tejaku" (), but instead members of a party pour for each other, which is known as "shaku" (). This has relaxed in recent years, but is generally observed on more formal occasions, such as business meals, and is still often observed for the first drink.
