Nakayaibei was the original brewer who branched out from the Kitahara family, who for generations operated sake brewing in Shinshu Takato. He discovered the charm of Hakushu water and decided to start brewing in the Koshu Kaido Daigahara area.
On the inauguration of the newly established main building fifth generation brew master Ibei Kitahara received a pair of fanlight from Takato Domain's daimyo Yoriyasu Naito as a celebratory gift. The fanlight was made by the same carpentry sculptor who built Suwa-taisha Senshiro Tatekawa, and the title was "Seven Sages of the Bamboo Grove" or "Chikurin no Shichiken" in Japanese, which is the origin of the current sake name "Shichiken".
During the Meiji Emperor's imperial tour through Yamanashi Prefecture, Mie Prefecture and Kyoto, in the inner parlor of the main building, there is an "Anzaisho" (a lodging built to accommodate an imperial visit). During this occasion, the 6th generation brewer, Nobuyo Kitahara, served as a chamberlain for one night. As an expression of gratitude, "White Habutai" (2 rolls of white smooth silk fabric) and "50 Yen" was received from the emperor.
The 10th generation brewer, Kusaburo Kitahara, established the corporation "Yamanashi Meijo Co., Ltd." and served as the very first president, actively managed the business and led to the prefecture's largest business achievement.
The "Anzaisho" in the inner parlor of the main building, which the Meiji Emperor used, has been assigned as a historical landmark by the Ministry of Education (presently the Ministry of Education, Culture, Sports, Science and Technology).
The 11th generation brewer, Shinji Kitahara, aimed for something no others could established at the time and decided to build the "Seiwakura" brewery. This led to the improvement of brewing techniques and quality.
The 12th generation brewer, Hyogo Kitahara, built the bottling facility and the product warehouse. He established the current structure of Yamanashi Meijo Co., Ltd.
Futsushu (ordinary sake) was discontinued and all products were changed into toketei meisho shu (sake with a specific class name).
Onakaya, an agriculture corporation limited company was established. A group was formed with the local farmers and manufacturers to start cultivating high quality rice.
The restaurant "Daimin" was opened serving seasonal dishes with local ingredients and providing a fresh take with Japanese sake and food.
Abolished Toji System and Ryogo Kitahara is appointed sake brewmaster.
From 2014 we took 5 years to renew the brewing facility Seiwakura to the latest models establishing a stable and high quality sake brewing environment.
Implemented the Shichiken Branding Strategy where newly design products were introduced with new labels and lineup that better suit the quality of our sake.
With an aim to develop new possibilities after 5 years of research we introduced three sparkling sake with second fermentation in the bottle "Yamano Kasumi" (2015), "Hoshino Kagayaki" (2016), and "Morino Kanade" (2017).
Tsushima Kitahara is appointed CEO and Ryogo Kitahara is appointed Managing Director.
