A healthy food rich in rutin! Stone-ground Hitachi Aki Soba: Fragrant and Additive-free

This is an introduction for Stone-ground Hitachi Aki Soba from Isemata Beikoku Seifun Co., LTD.


Stone-ground Hitachi Aki Soba comes in individual 200g bags of dried soba noodles. This soba is made completely free of additives.


Hitachi Aki Soba, known as ‘the very best gen soba’, is a fragrant soba with a distinctive sweetness and rich aroma which makes it different from other Ibaraki brands.It has received overwhelming acclaim from soba craftsmen and connoisseurs from across Japan.

Gen soba refers to soba made from buckwheat that has been harvested and remains in the hull.


Located in the birthplace of Hitachi Aki Soba (Hitachiota City, Ibaraki Prefecture), Isemata Beikoku Seifun Co., LTD. is a milling company specializing in Hitachi Aki Soba that was established from the founder's desire to spread this soba’s popularity.

As the company's priority is "the pursuit of the highest quality soba," the finest buckwheat is carefully selected then slowly ground on a millstone to bring out its full aroma and sweetness.

In the drying room, the final step of the process, the mills are turned on and off repeatedly according to the temperature and humidity of the day to produce high quality buckwheat noodles.


Soba is rich in ‘rutin’ which is said to help prevent lifestyle-related diseases as it supports vascular health and is rich in antioxidants.


According to President Tagano of Isemata Beikoku Seifun Co., soba pairs well with olive oil and tomatoes in Western style cooking, and with radish and natto in Japanese dishes.

We asked President Tagano to share his favorite recipe.
