Potato Kaitsuka Co. Ltd.
“An integrated manufacturing company specialized in sweet potatoes”


We are interviewing enterprises/organizations that are actively working in foreign exports and are member of the Ibaraki Global Business Promotion Council about their products!
We have asked Mr. Takahashi Yuto, person in charge of exports at Potato Kaitsuka Co. Ltd. headquartered in Kasumigaura City of Ibaraki Prefecture, about his company’s export goods, “Frozen roasted sweet potatoes (Beni-Tenshi)” and “Frozen dried sweet potato (Beni-Tenshi)”.

Potato Kaitsuka Co. Ltd.

Mr. Takahashi Yuto
Potato Kaitsuka is an integrated manufacturing company that handles various types of sweet potatoes and sweet potato processed goods. The company is able to handle about 20,000 tons of sweet potatoes a year.

The company’s factory consists of 4 towers, the first is responsible for cleaning and sorting, the second is the freezer, the third is for making dried sweet potatoes and the fourth is for making baked sweet potatoes.

The sweet potatoes are grown with the help of contracted farmers at the company’s farming facility. We have sweet potato fields that are well drained with machines through soil analysis and planned fertilizations. Our biggest advantage is our “curing process” carried out in curing storages. Our “curing process” is designed to keep sweet potatoes in a storage for a long time under specific conditions of temperature and humidity. This process naturally cures the sweet potatoes of any damages incurred during their harvest or other occasions. Sweet potatoes that undergo this curing process become remarkably sweeter and are able to be stored for longer periods of time.

“Frozen roasted sweet potatoes” and “Frozen dried sweet potato” made from Beni-Tenshi

Takahashi states: “I recommend our “Frozen Baked Sweet Potato” and “Frozen Dried Sweet Potato” that use “Beni-Tenshi”, our company’s original brand of sweet potatoes that have a sugar content of 47°Bx.

Frozen roasted sweet potatoes (Beni-Tenshi)

1 bag of “Frozen roasted sweet potatoes (Beni-Tenshi)” is 500g. Export orders starting from 11 cases, each holding 20 bags, are available.

Takahashi states: “By baking this product at a fixed temperature the sweetness of the sweet potatoes is brought out to its maximum, and it is this rich sweetness and sticky texture that are the distinctive characteristics of our baked sweet potatoes.”

“This product can be eaten by taking it out of the packaging and warming it in the microwave for 1 to 2 minutes, or in a toaster oven for 3 to 4 minutes.”

“When eating this product, you can defrost your desired amount of slices for 5 minutes at room temperature and eat them as is. Baking them in the oven for 2 to 3 minutes will bring out the product’s fragrant aroma.”
