Ohashi Ryoki is a special manufacturer of wooden Masu boxes. Beyond the concept that it is used as a measuring tool, we have been striving to enhance the attractiveness of wooden Masu boxes. The company is located in Ogaki, Gifu that proudly covers 80% of the national production of Masu boxes. Approximately 2 million pieces are shipped each year. It is made of hinoki cypress, not from a log but from the excess or leftover materials from house building. It can be said that Masu boxes are very environmentally friendly.
