Located in the rich nature of Aya Town in the central part of Miyazaki Prefecture, Oyama Foods Ltd. is a long-established vinegar brewing manufacturer that has been lasting for more than 80 years. They have been making traditional fermented foods since the fifth year of Showa period (AD 1930).
The Philosophy of Vinegar Manufacturing
In Miyazaki's abundant nature, "Aya's famous water" which is honed in the Japanese larch forest area is used for everything from brewing to mixing. All using the traditional brewing method.
Fermentation is done outdoors using huge turtle pots. It is a unique brewing method that has only been done by Yamadai vinegar in Japan.
Traditional Ancient Brewing Method
Yamadai vinegar is prepared by a process called "old style brewing method". It is a simple method of simply putting in 1/3 of the body of the turtle pot in the ground, then adding good quality ingredients like brown rice, water, koji, and vinegar starter culture in it. After that, bincho charcoal (white charcoal/bincho-tan) is put in, and the fermentation state is monitored with a five-yen coin. Furthermore with the old method, they let the vinegar naturally develop with the sun and the power of time.
In the turtle pots, koji starter culture, yeasts, and acetic acid bacteria are constantly active, and organic acids produced by them and amino acids in brown rice melt into raw rice vinegar.

Organic, Pesticide-free Rice
We are using only rice (white rice and brown rice) produced by organic farming, aiming to make vinegar that you can use safely.

Specialty Water
We are using "Aya Town's famous water" chosen by the Japan's Ministry of the Environment as one of the 100 most prestigious waters in Japan as the water for making all products. This water, which is also used in Miyazaki's famous tofu store, has a mellow taste.

Vinegar With Rare Black Koji
To make whole grain black rice vinegar, we use black koji, which is the progenitor variant of white koji. Black koji produces citric acid by itself, prevents contamination by various germs, and is suitable for brewing in tropical countries. On the other hand, it is difficult to make and maintain koji fermentation.
Vinegar brewing with black koji is unique in Japan.

Traditionally-made Turtle Pots
The turtle pots used to make this rice vinegar are huge. One turtle pot can brew 300 to 500 litres of raw rice vinegar. Because of the size, nowadays these pots are rarely produced.
Up to hundreds of turtle pots are embedded in the southern side of the Aya factory on the hill which has good sunlight.

Easy Recipes Using Black Vinegar
As a general guideline, take about 15cc to 30cc of black vinegar a day.
If you drink the undiluted solution as it is, the acetic acid component contained in vinegar may damage your throat and digestive organs, so it is recommended to dilute it about 10 times.
Here, we will introduce how to drink black vinegar deliciously and safely.
*Some products may be diluted to make them easier to drink. Please drink according to the product handling instructions.
