◆ Masu, originally used as a measuring cup

The origins of the masu go to back centuries... 

The existence of masu cups in the distant past of 1300 years before today in the Nara period has been confirmed. 

In Edo Period (1603 - 1868), the masu were used by merchants to measure for sale such important commodities as rice and other grains as well as soy sauce, vinegar and sake.


In Japan, people use the terms ichi-go (一合, one go) or i-ssho (一升,  equals to ten “go”) to measure rice or sake, and a level masu cup of rice is ichi-go, making for one to two servings of rice when cooked.


The metric system, which has been gradually taking over from traditional measurement methods, became the standard in Japan, and masu cups stopped being used for a measurement tool.

However, masu cups achieved a “revival” later on as free gifts to accompany Japanese sake and as commemorative gifts at celebrations, where they were appreciated for their beautiful grain and great aroma. 


Today, masu are often used for serving sake at sake barrel ceremonies "kagami biraki"

and at traditional Japanese pubs "izakaya" that appeal to the customer's sense of nostalgia

or "Japanese-ness."


Masu vary in size but the two most common sizes used for enjoying sake are

the 144 ml "hasshaku" masu and the 180 ml "ich-go" masu.
