The Origin of Banshu Ikkon

Using Rice that has benefited from the bountiful nature of Banshu (the south eastern part of Hyogo Prefecture),
as well as the water of Banshu, we value the original goodness of local sake,
cultivated in a climate with great temperature differences.

A glass of sake.
“Enjoy this sake we spared no time or effort brewing,”
was the inspiration behind the name.

The Abundunt Blessings of Banshu

Water from the Ibo River basin, which is the underground water of Mt. Hyono,
the highest peak in Hyogo Prefecture, is pumped from our company’s well and used as preparation water.
We use a pleasant tasting soft water that is about 30mg/L.
This water is an indispensable asset for us at our company,
as we aim for a smooth and soft quality of sake.

Sake rice, such as “Yamada Nishiki”, “Hyogo Kita Nishiki” and “Hyogo Yume Nishiki,”
among others, is native to Hyogo prefecture.
The Banshu region is the rice bowl region for sake rice, representing Japan.
It is our conviction that a Banshu brewery brews Banshu products with Banshu water.
We are particular about our sake rice, making sure that it is not rice that is merely grown in the prefecture,
but rice that is originally from Hyogo prefecture.

Making the Dinner Table More Plentiful.
Making More People Smile.

We aim for a sharp tasting sake where, although you may feel a steady savoriness (umami),
there is a suitable level of acidity that quickly disappears in the second half, making you want to drink another cup.

This isn’t a sake that you’ll enjoy with just a single sip.
Our ideal for “Banshu Ikkon” is a sake that is routinely placed on the dinner table,
made all the more delicious when paired together with a meal.

Adding a touch of color to the dinner table so you’ll be bound to smile.
We’d like to continue to brew sake that “makes more people smile”.

For that purpose, we make full use of old and new technologies and spare no effort,
taking the challenge of seriously making sake head on.

Kansai's Only Mine Storehouse "Meijugura"

A part of Banshu Ikkon’s sake is stored at “Meijugura” in the historic site of Meinobu Mine in Yabu City,
Hyogo Prefecture.
There is little temperature change within the mine throughout the year, and remains around 12°C.
The mine blocks light and there is no vibration.
It is a “natural cellar” suitable for long-term preservation of sake.
Sake that is anticipated to be stored in “Meijugura” is made to be gently aged, in order to give it a soft, deep, and smooth taste.
The mine is an important asset of ours that expands our possibilities with sake.

About the Head Brewer

7th generation, Yuichi Tsubosaka.
After graduating from college, he worked in a liquor wholesale business in Tokyo.
During that experience, he reconsidered his profession, saying,
“I want to make and deliver with my own hands what I think is
‘ the most delicious,'”
whereupon he joined Sanyohai Shuzo in 2008.
He has been in his current position since 2015 after receiving training at a specialized institution and mentorship under head brewer Tajima,
who had maintained the taste of “Banshu Ikkon” for many years.
Day by day in his profession, he continues to take the challenge of sincerely making sake head on.
