Step into the living history of sake at Saijo Sake Brewery, located in Osaka Prefecture, the historic brewery behind Amanosake, one of Japan’s oldest recorded sake styles. This winter-only brewery tour, available from late January to early March, offers a rare opportunity to experience sake-making at the very moment when the brewery is most alive.

Unlike standard sightseeing visits, this tour takes place during the peak of the brewing season, when the air is filled with the aroma of steamed rice and koji, and the quiet rhythm of fermentation defines each day. From the moment you enter the brewery grounds in southern Osaka, you are immersed in centuries of tradition rooted in the birthplace of Amanosake, a sake once offered to shrines and the Imperial Court.

Begin with a deep introduction to the brewery’s long history and cultural significance, explaining how Amanosake has been referenced in historical records for over a thousand years and how its philosophy continues to shape modern brewing. As you move through the kura, learn each step of the brewing process in detail, from rice preparation and koji cultivation to yeast starter and fermentation, with explanations tailored to what is happening inside the tanks at that exact time of year.

Because the tour is held during active production, observe techniques, sounds, and movements that are normally hidden from visitors, making this a timely and authentic encounter with a real working sake brewery in Osaka. The experience culminates in a tasting of fresh namazake, an unpasteurized sake that is rarely available outside the brewery and can only be enjoyed during this limited seasonal window.

Guided by knowledgeable staff, explore the vivid flavors, textures, and aromas that define namazake, gaining insight into how freshness and fermentation express themselves differently from standard bottled sake. This exclusive tasting is designed to deepen understanding rather than simply sample products, highlighting why timing and seasonality are essential elements of sake culture.

After the tour, choose to continue your experience across the street at the brewery’s partner restaurant, where local dishes can be enjoyed alongside Amanosake, allowing the story of the brewery to naturally extend into a dining experience. This optional meal pairing provides a meaningful way to connect sake with food and place, completing a journey that blends history, craftsmanship, seasonality, and Osaka’s lesser-known sake culture into a single immersive experience that cannot be replicated at other times of the year.
