On Wednesday, November 5th, Calbee will launch “Noriyan,” a new seaweed-alternative snack made from upcycled potato starch, exclusively at the Calbee+ Tokyo Station store.
Available in two flavors — Dashi Soy Sauce and Wasabi Salt — the product will be sold in limited quantities until stocks last.

Calbee Expands Sustainable Innovation with “Noriyan”

In line with its mid-term transformation plan “Change2025,” Calbee continues accelerating new-business development. “Noriyan” represents the company’s first-ever attempt to upcycle unused potato starch — a by-product of snack production — into a seaweed-like alternative.

Calbee processes approximately 371,000 tons of potatoes annually (about 19% of Japan’s total domestic production). In its factories, large quantities of potato starch are generated during the manufacturing of potato chips and “Jagarico.”
Recognizing the potential of this underutilized resource, the R&D team began developing a new material that could mimic the texture and experience of nori (seaweed).

The result is “Noriyan” — a crisp, thin sheet snack that recreates the feel of seaweed without using any marine ingredients.

Background: How a Young Employee’s Idea Became Reality

The concept originated from **Rinpei Kudo**, a third-year employee who submitted the idea to Calbee’s internal innovation program, **“Innovation & Beyond Festa.”** His inspiration came from news reports about *poor seaweed harvests and soaring nori prices*, prompting him to consider how Calbee could respond to this social issue through innovation.

Kudo proposed transforming unused potato starch into a seaweed substitute. Among 81 proposals submitted to the first Innovation & Beyond Festa, “Noriyan” won the grand prize.

Development was far from easy. Unlike seaweed, potato starch does not naturally form thin, flexible sheets.
Over two years and more than 2,000 prototypes, the team worked to:

Create a sheet that bends like seaweed

Achieve the signature “snap” when breaking

Reproduce the savory satisfaction typical of nori snacks

Their persistence led to the final product — a unique “potato-based seaweed” experience.

What Is “Noriyan”? Product Features and Flavor Profiles

“Noriyan” is made by coloring Calbee’s potato starch with plant-derived ingredients and baking it into an ultra-thin, crisp sheet using a proprietary process. The look, taste, and texture deliver a “this has to be seaweed!” moment.

Two Flavors

1. Dashi Soy Sauce (Pink packaging)
A comforting Japanese flavor made with bonito, scallop, and kelp — one of Calbee’s most beloved seasoning profiles.

2. Wasabi Salt (Green packaging)
Inspired by the sharp, satisfying taste of “Hard-Cut Potato Chips,” perfect as a snack or with drinks.

Packaging

Small, resealable pouch

Designed to show clearly that it is made from potatoes

Portable and convenient for snacking anytime

Innovation & Beyond Festa: Driving Calbee’s Future Vision

Calbee’s “Innovation & Beyond Festa” encourages employees across Japan and overseas to challenge assumptions and propose bold ideas. In 2024, the program received **84 proposals** spanning product concepts, services, and operational innovations.

Winning ideas receive structured support toward commercialization — embodying Calbee’s 2030 vision, “Next Calbee & Beyond.”

“Noriyan” symbolizes Calbee’s commitment to:

Upcycling unused resources

Reducing environmental impact

Creating enjoyable snacks that align with future sustainability needs
