Innovative Seaweed Snacks with a Crunchy Twist

In a groundbreaking move for the seaweed industry, Koyosen Honten Co., founded in 1894, is set to launch a novel product called "Zaku Nori Chips Umami Soy Sauce Flavor" on September 1, 2025. This innovative snack, designed in a unique wavy shape, aims to offer a crispy texture that appeals to snack lovers seeking a new culinary experience.

A Response to Global Demands

The journey toward developing Zaku Nori Chips began with feedback from Koyosen's international business division requesting the creation of a seaweed snack that could be enjoyed in a snack-like fashion. In Japan, seaweed is traditionally used to wrap rice or as part of rice balls. However, in Southeast Asia, there is a growing demand for seaweed that can be consumed as a standalone snack. Recognizing this market potential, Koyosen started to explore a new direction for their products, aiming to develop seaweed that satisfies this craving.

Inspiration from the Craft of Japanese Culturals

The product development team initially pondered whether the difference between traditional seaweed and snack foods might lie in texture. While typical seaweed is known for its "crisp" and "crunchy" qualities, the team felt these attributes were insufficient compared to conventional snacks. After testing various methods, including changing the soaking liquids and piercing the seaweed, they encountered a limitation with flat seaweed. Thus, they shifted their focus to creating seaweed that has a more three-dimensional structure.

During a stroll through Kappabashi Dougu Street—a well-known area for kitchenware—one developer noticed an "Oni Sudare," a traditional Japanese tool that exhibits a wavy structure. This discovery sparked the idea to craft seaweed into a wavy shape, which could potentially result in a unique texture akin to potato chips.

A Breakthrough in Flavor and Functionality

Moreover, the task of creating a seasoning blend for the new chips posed its own challenges. Conventional flavored seaweed often leads to sticky hands over time, which could deter consumers from enjoying it as a convenient snack. Partnering with a trusted seasoning manufacturer, Koyosen created an innovative coating that minimizes stickiness, ensuring that consumers can enjoy their Zaku Nori Chips without worry, whether in the office or on the go.

Elevating the Eating Experience

The final Zaku Nori Chips Umami Soy Sauce Flavor deliver an entirely new texture that bridges the gap between seaweed and potato chips. The unique shape generates a delightful crunch, allowing for a longer-lasting taste experience as the flavors unfold gradually with each bite. The angles and depths of the wavy design have been meticulously calculated to provide optimal texture and flavor release.

Healthy and Guilt-Free Snacking

With health consciousness on the rise, Koyosen has ensured that their chips are low in calories at just 27 kcal per 8-gram bag—remarkably lower compared to the typical 540 kcal in a standard bag of potato chips. This makes Zaku Nori Chips an ideal choice for those watching their weight or seeking a nutritious snack option
