Watahan Launches Buzzworthy 'Kama-daki Kanpyo-maki' - Traditional Pot-Cooked Sushi Rolls with Weekend Red Vinegar Edition

Watahan Home Aid Co., Ltd. (Nagano City, Nagano; President: Yukiharu Nagaoka) will launch the 'Kama-daki Kanpyo-maki' (Pot-cooked Dried Gourd Rolls) on Wednesday, April 1, 2026. This product gained significant attention when it was featured on television earlier this year.

— Kanpyo Crafted with Traditional Dedication —

While many modern processes use pressure cookers for speed, this product intentionally adopts the traditional 'Kama-daki' (pot-cooking) method. By selecting only high-quality kanpyo and simmering it slowly in large pots, the flavor penetrates deeply. This process also ensures a crisp texture that remains tender even after heating.

— Weekend Exclusive: Special Red Vinegar Edition —

Furthermore, on Saturdays and Sundays only, a special edition will be sold using 'red vinegar' in Watahan's original sushi rice blend. The unique depth and mildness of the red vinegar enhance the ingredients' flavors and prevent the rice from becoming dry when refrigerated.

— Renewed Natto-maki with Domestic Ingredients and Selected Bacteria —

In conjunction with this launch, the 'Domestic Natto-maki' has also been renewed. Using low-fat domestic soybeans ground just before processing at the factory to maintain freshness, and employing carefully selected natto bacteria, the natural umami is maximized. The result is a roll with a mild aroma and perfect softness that keeps you coming back for more.

Please enjoy our 'Kama-daki Kanpyo-maki' and 'Domestic Natto-maki' for your daily meals or as a weekend treat.
