We aim to be a food manufacturer that can provide our customers with impression, satisfaction, and peace of mind.

We would like to express our sincere gratitude for your continued support and patronage.
Our company began its operation as Moriyama Dairy Products Ishioka Factory in the December of 1941, and became independent as Tsukuba Dairy Products Co., Ltd. in June 1951.

In March of 1973, we joined the Shoei Foods Corporation group and began processing nuts in addition to producing dairy products in June of 2000.

We strive to further advance nut-processing technology as well as the dairy-product production technology and the quality-control system that we have acquired since our establishment. We unremittingly pursue consumer peace of mind and safety to deliver inspiration, satisfaction and safety.
We make every effort to contribute to the development of the domestic dairy industry.
For the next 100 years, we will continue to take on the challenge of manufacturing and aim to be a company that spreads its wings around the world.
We would appreciate your continuous understanding and support.

Corporate Logo

What we put into our logo

The previous logo mark is familiar to our employees as well as to our customers and business partners. We have created a new logo that is an adaptation of the previous one, while maintaining the “our history of 80 years in business” and the brand value of “TSUKUBA DAIRY PRODUCTS” that we have built up over the years.


T.K.B.”, which was drawn under the two lines of the previous logo, has been moved out of the circle and changed to “TSUKUBA” so that all people can understand the logo.

Two lines at the foot of the mountain

It represents Lake Kasumigaura, which provides us with the blessings of nature. It also represents our two pledges of “consistent quality control from raw materials to finished products” and “safe and secure manufacturing”.

Two mountains

They represent Mt. Tsukuba, which is a symbol of Ibaraki and has been loved by the people of the region since ancient times. They also represent the company’s intention to be loved as a company rooted in the community like Mt. Tsukuba. The mountains are connected by a single line, and the image of infinity is expressed with a desire for further development.


The color “red,” is the same as one of our core products “Sweetened Condensed Milk”, and represent our devotion with “passion” from manufacturing to delivery to our customers.
