In Japan, it is commonly called a "sake set". A sake set often includes a tokkuri or carafe and a sake cup. A tokkuri is a bottle for pouring sake, and a sake cup is a small cup for drinking sake.
In Japan, the term "sake cup" is generally collectively called "shuki" or "shuhai," but there are several other names depending on the specific shape and use.
Japan, an island nation, has nurtured its own culture and traditions since ancient times. Among these, the unique Japanese sake culture has been deeply rooted in all levels of society throughout its long history.
