Long-selling 'Shijimi Shukan' of over 20 years now available as a food product for the first time. A new proposal as an 'everyday cup' easily incorporated into daily meals.

Sizenshokken Co., Ltd. (Location: Bungotakada City, Oita Prefecture, Representative: Kohei Sasaki) will launch 'Shijimi Shukan Miso Soup,' a new product that is the first food item to utilize the clam extract powder used in its health food long-seller 'Shijimi Shukan,' which has been sold for over 20 years. It will be available from May 11, 2026, with a limited release of 3,000 bags.

In recent years, as opportunities to review health consciousness and daily eating habits have increased, Sizenshokken has aimed to create products that allow people to easily enjoy clams in their daily meals. 'Shijimi Shukan Miso Soup' is a product developed as a powdered miso soup that can be easily incorporated into daily meals, leveraging the knowledge gained from 'Shijimi Shukan,' which has continued for over 20 years.

This product uses the same clam extract powder as 'Shijimi Shukan.' The concentrated extract made by boiling clams is powdered as is, allowing you to easily enjoy the original umami of clams.

■ Development Background

A new proposal to meet the needs of 'taking in nutrition through meals' amidst rising health consciousness and a review of eating habits.

While selling 'Shijimi Shukan' for over 20 years, Sizenshokken has conducted customer surveys for product development. Amidst increasing health consciousness and a review of eating habits, there is a growing need to effortlessly incorporate nutrition into daily meals, not just through health foods. Among the desired products, 'soup or miso soup made from clams' has always ranked high, revealing a need to enjoy clams more easily as part of a meal.

A major point in development was to adjust the strong flavor of clam extract into a taste that can be consumed daily. Therefore, Sizenshokken blended ginger. By utilizing the umami of clams and adding the flavor and aftertaste of ginger, it was finished with a taste that can be enjoyed as a daily cup with meals.

As a powdered type, it can be easily consumed by just adding hot water, making it suitable for various scenes such as busy mornings, as a side dish, a finishing cup for meals, or during business trips and travel. Furthermore, it can be widely enjoyed not only as miso soup but also as a seasoning, such as a condiment for cold tofu, flavoring for fried chicken, or a topping for rice balls.
