Nose and taste

You can set subtitles in English, Japanese, French, Traditional Chinese, and Simplified Chinese.

“Following the initial impression of the nose, it shifts to an earthy scent reminiscent of roasting, perfume, high-quality hardwood, and Cuban cigars and black truffles, progressing to aromas of forest, game meat, and caramel as it reaches completion.”

“Even after nearly 50 years of aging, this sake provides a moving experience, with the distance and depth of flavor proving the true potential of sake.”

Product introduction

KUROKOHAKU is a product of Shiratamachi terroir for which its existence itself is miraculous, and it is finally going on sale.

This Shiratamachi terroir "KUROKOHAKU" kijoshu koshu (aged sake) was brewed over a three-year period starting in 1972 in preparation for the development of kijoshu.

The rich nose and deep taste are truly unique.
At the IWC (International Wine Challenge), the world’s largest competition, it earned the trophy for the #1 aged sake in the world.

In order to elevate this miraculous sake which can never be brewed again into a true product of the Shiratamachi terroir, it has been wrapped in 100% mulberry fiber Miyama washi paper, a traditional craft of the area with a nearly 400-year history, and packaged in a wooden box made by globally-praised woodworking artisans from natural wood materials cut from the Shiratamachi cedar forests.

The "SakeArtisan project" created this limited-edition miraculous KUROKOHAKU product in cooperation with the brewer, Kamogawa Shuzo. Sales will be limited to a total of 200 pieces for the year. The cost per set is 1,000,000 yen plus tax (for Japanese purchases, 1,100,000 yen total). Please be aware that pricing may change after this year as the product availability becomes increasingly scarce.

Sake (kijoshu)

Alcohol content

This kijoshu was brewed by Kamogawa Shuzo, a member organization of the Kijoshu Association located in Yamagata Prefecture’s Shirakatamachi, over a three-year period starting in 1972. Records of this kijoshu are listed in a production report submitted to the tax agency for the local municipality to manage records of sake production.
Normally, Japanese sake is made with rice, malted rice, and water as its ingredients, but kijoshu uses sake in place of the water. This gives it a distinctive rich sweetness and mild acidity. The National Brewing Laboratory (now known as the National Research Institute of Brewing) proposed this method based on a historical document (dated 927) which attempted to create “a luxury Japanese sake suited for pairing with meals.

Wooden Box

13 x 13 x 33 cm
Raw materials
Cedar from Shiratakamachi, Yamagata

Made by the wood artisan Shuji Nakagawa using natural cedar grown in Shiratakamachi.
Each wooden box is cut individually, so the wood grain, color, and appearance vary for each product.

Raw materials
100% mulberry fibers from Shiratakamachi, Yamagata

This paper is a traditional craft of Shiratakamachi called “Miyama washi.” It is used to wrap the sake.

Just as the "kijoshu" included in the KUROKOHAKU product package is a rare product, the wooden boxes used are each crafted individually to match the expressive qualities of the wood, and both the bottles and the boxes are engraved with individual serial numbers.
