Sake set
Sake set is a generic term for the flask and cups used to serve sake. Sake sets are commonly ceramic, but may be glass or lacquered plastic. The flask and cups may be sold individually instead of as a set.
A tokkuri is a sake flask or pitcher. Tokkuri are generally bulbous with a narrow neck, but may have a variety of other shapes, including spouted serving bowls (katakuchi). Heated sake is often warmed by placing the sake filled tokkuri is a pan of hot water.
The cups used for drinking sake are generally small cylindrical vessels called ochoko, but may also include flatter shapes such as wide-mouthed bowls. Sakazaki are more ceremonial cups used most commonly at weddings and other special occasions. Sake is also sometimes served in the United States in shot glasses.
Other sakeware
Masu
The wooden box cup, or masu, is a traditional serving vessel but is escewed by sake purists because the wood effects the flavor of the sake. In some of the more traditional Japanese restaurants, as a show of generosity, the server may put a glass inside the masu (or put the masu inside a saucer) and pour until the sake overflows and spills into the secondary container.
Stemware
Some manufacturers have discussed making sake stemware which is essentially a glass sake cup elevated above a vase.
Riedel
Austrian crystal manufacturer Riedel, as part of their "O" collection of varietal-specific glasses, created an "O" Sake Set of two glasses and a carafe.
