Beat Summer Somen Monotony! Proposing New Enjoyment with Kappo Shiradashi (Savory White Dashi) - "Let's Enjoy Somen with Yamaki Kappo Shiradashi! Campaign" to be Held on Official Instagram

Yamaki Co., Ltd. (Headquarters: Iyoshi, Ehime Prefecture; President and CEO: Yoshihiro Kido; hereinafter "Yamaki") will hold the "Let's Enjoy Somen with Yamaki Kappo Shiradashi! Campaign" on its official Instagram starting at 12:00 PM on July 1, 2026, as a proposal to overcome the monotony of somen, a staple summer menu item.

This campaign will introduce somen arrangement recipes using "Yamaki Kappo Shiradashi®" and propose new ways to enjoy it easily at home. Furthermore, to allow participants to experience new ways of enjoying somen, 30 winners will be selected by lottery to receive a Yamaki product set.

Background

Somen is widely popular in its classic style enjoyed with mentsuyu (noodle dipping sauce) and is an indispensable menu item on summer dining tables.

On the other hand, a survey by the cooking media "Nadia" revealed that over 70% of people feel "bored with the taste or way of eating" summer noodle dishes (*), indicating a need for arrangements in addition to the standard way of eating.

Based on these needs, Yamaki proposes somen arrangements that leverage the umami of dashi unique to "Yamaki Kappo Shiradashi®." Two dishes, "Somen with Prosciutto and Yuzu Kosho Flavor" and "Cold Soy Milk Somen with Tuna and Tomato," are introduced as menu items that allow for more creative enjoyment of somen. Both recipes are finished with a refreshing yet satisfying taste by combining the umami of dashi with the ingredients. The characteristic is that you can enjoy your usual somen with a different taste using familiar ingredients that are easy to incorporate.

Through this campaign, we aim to expand the usage scenes of "Yamaki Kappo Shiradashi®" in summer noodle menus and provide an opportunity to enjoy regular somen more deliciously.

* Survey on "Noodle Dishes" conducted by the cooking media "Nadia" (conducted from April 27 to May 1, 2026, with responses from 1,166 Nadia users who cook)
