In this campaign, the "Mentsuyu Cushion", which was well-received when posted on our official X account on April Fool's Day, Wednesday, April 1, 2026, will be turned into actual merchandise. 50 winners selected by lottery will receive a set of presents including the "Mentsuyu Cushion", a "Mentsuyu Acrylic Key Chain", and Yamaki products to enjoy for the upcoming summer.
■ Sparked by an April Fool's post, the "Mentsuyu Cushion" becomes real merchandise!
Yamaki, as a "Katsuobushi and Dashi Company", offers products that are easy to incorporate into dining tables, and its core product, "Mentsuyu", is an indispensable seasoning for daily cooking. This project was carried out transcending the boundaries of such product development, with the aim of having consumers feel familiarity and enjoyment towards the Yamaki brand.
When we made a humorous post announcing the "Release of Mentsuyu Cushion" on our official X account as an April Fool's project on April 1, 2026, we received a great response on social media, with comments such as "I want it!" and "I want to give it a tight squeeze."
In response to these reactions, Yamaki has officially decided to turn the "Mentsuyu Cushion" into actual merchandise. This is an initiative realized through communication with consumers via social media, and we aim to continue creating new touchpoints that allow SNS users, including our followers, to feel closer to the brand.

■ Special features of the prizes
The highlight of this time, the "Mentsuyu Cushion", reproduces the real package not only on the front but also down to the details on the back. In particular, the text on the back is filled with playfulness, making it enjoyable to read. You can use it as a cushion during your relaxing time at home or while working remotely.
Also, the "Mentsuyu Acrylic Key Chain", which was produced to commemorate "Katsuobushi Day (November 24)" and received favorable reviews for being "Cute!", has been prepared again in conjunction with this campaign. Furthermore, as a set of Yamaki products to get a head start on summer, the lineup includes "Straight Somen Tsuyu" and "Straight Soba Tsuyu" in addition to the classic "Mentsuyu".
