After the resignation of Masatake Terauchi's cabinet under the influence of rice riots, Takashi Hara of the constitutional political friendship society formed his cabinet for the government as the prime minister in 1918. Japan signed the Treaty of Versailles and joined the League of Nations. In cooperation with the United States, Japan participated in the Washington Conference to discuss then the issues of Pacific of Asia and pushed diplomacy forward eagerly. Also, the then president head, Seto Shuzo Brewery, a political friendship society member had interchange with Takashi Hara. Our president head had continued making sake with a brand name of Maruhei Masamune since the establishment of a business, but he was considering a new brand name as the result of a corporate status of his company.​Our president head was invited by the Prime Minister on the occasion when navy large-scale maneuvers were carried out in Nagasaki. He asked the Prime Minister to give a new name to sake. Then, he named it Azumacho, saying "The sake makes me feel and happy. It's worthy of praise as king of Sake for its smooth and plump taste". Azumacho has come down to us since then. We continue to make excellent sake worthy of inherited brand name of Azumacho.
