Story of the Masu and Overflowing Sake

At Rei, we often serve sake in a glass set inside a small wooden box called a masu. When the sake is poured until it overflows into the masu, it’s more than just a visual gesture — it’s a symbol of generosity, hospitality, and abundance.

This tradition dates back to Japan’s Edo period, when the masu was originally used for measuring rice — a precious commodity and symbol of wealth. Pouring sake to the point of overflowing expresses the host’s wish to share prosperity and happiness beyond measure.

In today’s setting, it remains an act of omotenashi — heartfelt hospitality — offering guests more than they expect, and inviting them to drink with gratitude and joy.
