(Papers prepared at medical conferences on obesity and diabetes in 2006)

Concerns about obesity and solving obesity all together are growing. Setting our goal not to produce a single diet failure, we will continue our endeavors in supporting our customers to successfully lose weight with our experience and knowledge.


Health, Beauty and Safety

More than Just selling our products,
we wish to make our customers happy and
satisfied by guaranteeing their effectiveness.
This is our unflagging corporatepolicy.

That dieting is a popular subject of conversation today is a reflection of the growing concerns both men and women have about obesity. We realized, though, that the mark was lacking in effective products and a weight management system backed by a sound theory. Our company, then, decided to launch a safe dieting product MICRODIET while providing our customers, through various method, correct information and theory on dieting. We have been focusing on making our business customer-oriented by lending an ear to our customer's request and suggestions. As a result, our endeavor have been appreciated by our customers throughout Japan.

We sell our products with confidence and strive to achieve our final goal of fully satisfying our customers. To be trusted by our customers is what we believe the highest appraisal a company can be given.

As we strengthen our collaboration with medical institutions, we will continue to pursue our dieting system from counseling to support as we endeavor to contribute to society with a goal perspective by fulfilling our corporate motto, “Health, beauty and safety”

Corporate activities

MICRODIET has been used for patient’s meals in hospitals and medical institutions for treating obesity. The clinical data accumulated through this has been often reported at medical conferences. We presented a report on our test results at international conference in 2006 on obesity and diabetes.

To be successful in dieting, one needs to have correct information. To support our customers who have purchased MICRODIET products we present them with a guidebook and DVD on dieting and food. The MICRODIET ONLINE also contains a variety information on these topics.
We have held MICRODIET Weight Loss Grand Prix every year to reward those customers who have shown out standing results in reforming their eating habits and lifestyles. We also provide counseling and service to our customers who seek advice during dieting.

As part of our counseling service, our customers can access to the Community Site and even receive encouragement and advice from those who have succeeded in dieting when experiencing trouble or stress while on diet.
Feedback from our customers have been an incentive for us to create new products which is reflected in our development of the risotto type, pasta type, cereal type and low calorie regular menus products as well as in our rice, noodle, desert and snack menus.
The wide variety of our lineup has been developed to provide our customers with a sense of satiety and satisfaction and to alleviate their feeling of hunger and deprivation- a stress factor often experienced during dieting.
