Introducing Sakamoto Kurozu, a traditional Japanese vinegar from the 1800s. This cool amber rice vinegar not only enhances the flavor of your meals but also has potential health benefits, including improving brain health and possibly preventing dementia.
Sakamoto Kurozu sticks to tradition. The makers only use three ingredients: koji rice, steamed rice, and water. They then allow it to ferment and age for 1-3 years in handcrafted ceramic Satsuma jars. The unique part is that the microorganisms living on the inner walls of these jars contribute to the unique production process.
Vintage Goodness in a Bottle
The unique vinegar comes from the southern-most tip of Japan’s mainland. The production process takes place in an environment rich in natural elements. These elements contribute to its distinct flavor profile. The vinegar ages in open-air ceramic jars. The jars are strategically placed to absorb solar energy, using the sun’s power to aid the aging process.
In addition to the sun’s energy, beneficial micro-organisms work hard to enhance the aging process. They help break down the raw materials, transforming them into a remarkable vinegar in taste and appearance. After a year of aging, the vinegar takes on a deep amber color. The taste, which was raw and potent, becomes smooth, creating a robust and refined flavor.
This unique method of vinegar production, known as “Kagoshima no Tsubozukuri Kurozu,” is more than just a process – it’s a tradition. Japan’s Geographical Indication system protects it, ensuring that only vinegar produced this way and in this location can carry the prestigious “Kagoshima no Tsubozukuri Kurozu” name.

The Story of Artisan Amber Rice Vinegar
The Sakamoto Kurozu, also known as the Artisan Amber Rice Vinegar, first appeared in the historical and culturally rich Kagoshima prefecture of Japan around the 1800s. This prefecture, known for its warm climate and exceptional water quality, provided the ideal conditions for creating this unique vinegar.
Another key component in Sakamoto Kurozu’s production is the unique earthenware jars used for aging. These jars, steeped in tradition and crafted with precision, contribute significantly to the distinctive flavor and quality of the vinegar. These elements – the climate, the water, and the earthenware jars – come together to create some of the best rice vinegar on the planet. This vinegar enhances the flavor of food and carries a piece of Japanese history and culture.
For nearly 40 years, national universities and public research institutions have been studying Sakamoto Kurozu to explain its health benefits. Once word got out in Japan about these benefits, Sakamoto Kurozu began to be used not just for cooking but also as a health drink, triggering a health drink craze.

They perform strict quality tests and ingredient analyses in their R&D department using the latest testing equipment. The vinegar is bottled in a super clean, state-of-the-art factory with FSSC22000 certification, an international standard of food safety.

This certification ties the high quality and rich history of Sakamoto Kurozu to the place it’s made. Authentic Sakamoto Kurozu can only be made in Fukuyama, which makes it a genuine product both in Japan and around the world.
