The best ingredients deserve the best effort and technology.

Fried Potato Inoue-shiki is an "exceptionally labor-intensive method" developed to fry the finest potatoes from Tokachi Inoue Farm in the best possible condition. The potatoes from Inoue Farm are loved by top chefs, but they are also delicate due to their exquisite taste. Our unique French fry artisan's method and philosophy were born from tackling this high hurdle. We named it "Inoue-shiki" (Inoue Method) in honor of this. We transform not only Inoue Farm's potatoes but also carefully selected potatoes that prioritize deliciousness into ultimate French fries using this "Inoue Method."

Three Features of Fried Potato Inoue-shiki

From a side dish to a main dish. Craftsmanship infused into French fries.

01. Ingredients

The best French fries start with the best ingredients. We carefully selected the finest May Queen potatoes, grown in the fertile land of Obihiro, including Japan's pride, "Tokachi Inoue Farm's" May Queen.

02. Method

Craftsmanship infused into French fries. After trial and error, we arrived at the "three-stage preparation method," which leaves no room for compromise from the steaming process to the double frying. We respect the ingredients, spare no time, and exert our skills.

03. Texture

The surface is surprisingly crispy and crunchy, and the inside is magically creamy and fluffy. This is a masterpiece that redefines the common perception of French fries and can truly be the "main dish." Please experience this unprecedented taste sensation with your own tongue.

Fried Potato Inoue-shiki Product Lineup

"Aged French Fries Futoyoshi"

Sweet as honey, sensual. The shock of "crunchy and creamy" unleashed by two winters of aging.

Can you imagine potatoes with sweetness that surpasses sweet potatoes? The ingredients are "Tokachi Inoue Farm's" snow-aged sweet May Queen potatoes, which have been dormant in a snow-aged cellar for two winters. This rare potato, whose starch has converted to sugar and whose cross-section is transparent like a jewel, is a treasure that even renowned chefs visit to inspect. Artisan Masashi Nagai has refined this luxurious ingredient to the extreme using the "three-stage preparation method." One bite, and immediately after the powerful crunchy texture, a rich sweetness overflows from the inside. A culmination of the finest ingredients and Japanese technology, this is an unprecedented "uncharted territory of deliciousness." It will surely stimulate all five of your senses.

"Aged French Fries Ichifuyugoshi"

Moderate sweetness and flavor from aging.

"Crunchy and juicy" with a golden balance from one winter's aging.

The ingredients are May Queen potatoes aged for one winter, offering a pleasant golden balance of aging sweetness and freshness. While retaining the light flavor and fluffy texture of "Tokachi Inoue Farm's" snow-aged sweet May Queen, the deep umami and richness unique to one winter's aging are added, shifting to a perfectly sticky and moist texture. It's not extremely rich like the super-long aging of Futoyoshi, but the moderate aging that makes you want to eat it daily is causing many to become hooked.

"Standard French Fries Three-Stage Preparation"

The new standard for French fries. The ultimate "crunchy and fluffy."

Our standard "Three-Stage Preparation" French fries aim for an overwhelming "crunchy and fluffy" sensation. We carefully selected the finest May Queen potatoes, primarily from Tokachi Inoue Farm and grown in the fertile land of Obihiro. To preserve their rich flavor and aroma, French fry artisan Masashi Nagai prepared them using his signature "three-stage preparation method." The satisfying crunch is followed by the robust, fluffy texture of the potatoes themselves. Here lies the "correct answer" for French fries, evolved by the artisan's skill. Once you taste them, you can never go back to ordinary fries.

About the Potato Producer for Fried Potato Inoue-shiki

Shinya Inoue of Tokachi Inoue Farm

A farmer in Tokachi, Hokkaido. He produces special May Queen potatoes that have overwintered in a snow-aged cellar, with many top chefs as fans. Mr. Inoue's specialty is "snow-aged ripening." May Queen potatoes, harvested after accumulating sufficient starch, are stored in a snow-aged cellar utilizing natural snow. When May Queen potatoes are cooled to near 0°C in the snow-aged cellar, the starch converts to sugar, and they are protected from freezing. This transformation makes them sweet and "sweet-ripened." Furthermore, as the snow gradually melts, a moderate humidity is maintained, protecting the May Queen potatoes from drying out. Through such research-based methods, high-quality, special snow-aged sweet May Queen potatoes are completed.

Mr. Inoue's "Snow-Aged Sweet May Queen"

"Snow-Aged Sweet May Queen Ichifuyugoshi" (aged for over 6 months after harvest) has a sugar content of about 9 degrees and is characterized by a good balance of potato flavor and sweetness, making it easy to use in everyday cooking. "Snow-Aged Sweet May Queen Futoyoshi" (aged for over 18 months after harvest) has a sugar content of about 12 degrees, and its sweetness and honey-like texture are reminiscent of sweet potatoes.

Craft French Fry Artisan Masashi Nagai

A craft French fry artisan based in Obihiro. He meticulously selects all kinds of potatoes and pursues the ultimate French fries that can be the main dish. Upon encountering the snow-aged sweet May Queen potatoes that overwintered in Tokachi Inoue Farm's snow-aged cellar, he was inspired to "create the world's best French fries using these finest potatoes." While constantly engaging with Mr. Inoue's potatoes, he developed the "three-stage preparation method," a manufacturing process that, although labor-intensive, makes French fries exceptionally delicious. His most cherished principle is achieving a deliciousness that can only be attained through manual labor, which is impossible in factory production. To achieve this, he possesses a craftsmanship that deliberately chooses inefficiency. These are likely the most expensive French fries in Japan. However, he researches French fries daily for restaurants that understand their high quality.
