The word "Daege" used by Daiguchi Co., Ltd. comes from the term "rank" in sumo wrestling in traditional Japanese fighting skills. About 130 years ago, the brand name changed from "10,000 taels" to "Daguan". It is not just because of the corresponding "rank" in sumo, the word "big mark" also has the meaning of "very outstanding" and "dominant".

In the era of lack of mass entertainment in Japan, sumo wrestling is an event that is crowded with people. It can have the same name as the sumo rank, and its brand value and recognition will also increase. At the sumo wrestling conference held in Osaka in 1900, because the "Daguan" was awarded as a winning prize, its brand was quickly widely recognized among the people. Reaching the level of the winemaking industry is the corporate spirit represented by the "big mark".

About 80 years ago, Daiguan raised new signs in newspapers using a rare public reward method, and the plan was designed by Kobaya Kobayashi, a Tokyo-based cartographer, designed by Yokota Kobayashi. The combination of the strappy rope and the crotch cloth is also refreshing. To this day, Daguan is still passing on this design style.

Daguan has two wine cellars, "Shouroon" and "Henghe" . Here, the winemaker's five senses and superb skills are exerted. 【Shouro] Brewing Japanese wine mainly consists of high-end wines. New technologies are introduced on the traditional winemaking process to ensure high quality while effectively improving production efficiency.
