Obata brewery distills Sado’s charms into sake

Obata Sake Brewery was founded in 1892 on Sado Island in Niigata Prefecture. Rumiko Obata, the fifth-generation manager of the brewery, which has been making sake for over 130 years, is now working to protect and nurture sake culture from various approaches, including efforts to preserve the rich natural environment that is essential for making delicious sake and building a bridge between Sado and the world.

After attending a university in Tokyo, she stayed in the city and worked as a publicist for a major film company. But when her father fell ill, she asked herself, “If tomorrow were the last day of my life, what would be the last thing I would want to do?” Her answer was clear: “I would want to take a last sip of my family brewery’s sake.” Then she decided to return to her hometown with her husband and take over the brewery at the age of 28.

Solar panels near Gakkogura generate electricity used at the brewery, helping make its sake brewing process sustainable.

She believes that the rich natural environment is the source of Sado’s charms, and in 2003 began exporting her sake to other countries to promote the island. “We think that sake should tell the story of the region where it is produced. That is why we have been working to put local characteristics into our sake,” she said. All of their sake strongly represents Sado’s regionality through its ingredients, brewing methods and compatibility with local foods.

In 2008, she came across Nishimikawa Elementary School, which was scheduled to be closed in two years. It is located about a 15-minute drive along a coastal road from Obata Sake Brewery. From the school building, which stands on a cliff, one can see the sunset on the ocean. “My husband said it would be a waste to let it fall into ruin, and that we should use it as our second sake brewery, but I vehemently opposed the idea,” she said. Although sake exports had been increasing year by year nationwide, they still accounted for only 1.8% of total shipments in 2008, and domestic shipments had declined by over 40% in the previous decade. It is not surprising that she was reluctant to invest in a new brewery. “But my husband brought me to the place, saying I should see it anyway. When I saw the view from the top of the hill on which the schoolhouse stands, I was struck by the beauty of Sado Island all over again. I couldn’t help but turn to my husband and say, ‘We have to do this,’” she said.

The brewery is now called Gakkogura (School Brewery) and has primarily been used as a base for sake brewing since 2010. Sake brewing normally starts in winter, but Gakkogura makes it possible to brew sake during the hot summer months by creating a wintery environment inside the building. Furthermore, weeklong programs offer experiences in brewing sake, mainly during the summer. Despite the lack of advertising, the programs attract many participants from overseas, indicating a high level of global interest in sake.

The programs ensure that the participants not only experience the brewers’ work, but also mix with the local community and get a taste of the Sado lifestyle. The programs have become familiar to the locals since their launch eight years ago. The townspeople do not hesitate to greet participants they happen to meet on the street, saying, “Oh, you must be one of the ones taking part in the brewing program.”

Last year, a cafe was established in a corner of the school building, with a view of the sea. It serves foods, desserts and drinks combining rice malt and byproducts like sake lees with other ingredients produced by local farmers, contributing to reducing food waste and food loss.

Solar panels have been installed near the school building to increase the percentage of renewable energy used to power the facility. This has implications that go beyond achieving zero carbon emissions. The facility’s ability to operate independently without relying on outside resources would play a role in supporting the community in the event of a disaster or other emergency. “We wanted to create a model that can realize our daily lives, tourism and emergency preparedness on a single platform,” Obata said.

The selection of materials for sake brewing also reflects the company’s commitment to the region. Some of the rice it uses comes from paddies that utilize crushed oyster shells as a soil conditioner. The oysters are cultivated in Lake Kamo in the eastern part of the island, near the port where ferries connect the island to Niigata. This is one of the environmentally friendly farming methods employed in Sado to nurture the Japanese crested ibis and other wildlife. The wild Japanese crested ibis was once driven to extinction. But in Sado, thanks to the breeding, release and protection of the birds, they can now be seen in rice paddies all over the island.

In the southeastern part of Sado Island, there are rice terraces with a 400-year history, called Iwakubi Shoryu Tanada (Iwakubi Rising Dragon Rice Terraces). As the name suggests, about 460 paddies of various sizes are arranged in a staircase pattern, filling the valley as if a dragon were ascending into the sky. The paddies, created to make the most of the hilly land, are small with irregular shapes, making it impossible to farm them with large machines. “We learned that the rice farmers in the area are facing a lack of successors partly because of the amount of hard manual labor,” Obata said. “We have been purchasing their rice since 2019 in the hope that their efforts pay off. Ryu no Megumi (Dragon’s Blessing) is the name of the sake we make from their rice.”

She pointed out that sake brewing in Japan has always been a communal effort, using sustainable methods handed down for generations, which is why many breweries have survived to be centuries old. “Letting this become known to the world through sake and the sake-brewing experience will help increase the presence of sake in the world and expand its market. That will allow us to continue sake brewing and rice farming as well as efforts to preserve clean water, nature and the landscape, forming an enduring cycle,” she said.

Gakkogura Cafe serves food and drinks made with sake lees and other sake-making byproducts and ingredients.

Former classrooms are now used for things like a library of sake-related materials and other books, and a lecture room for workshop participants.

Obata Sake Brewery makes various kinds of sake.


Rumiko Obata grew up in the sake world as the second daughter of the family that runs Obata Sake Brewery on Niigata Prefecture’s Sado Island. The brewery was founded in 1892 and produces various kinds of sake made from locally produced rice, including Manotsuru, its signature sake, which has won multiple awards. She took over as the fifth-generation owner in 1995 and established Gakkogura (School Brewery) in 2014 using the building of an elementary school that had been closed in 2010. In 2022, a cafe and an accommodation facility for participants of the brewery’s sake-making workshop were constructed inside the building.
