The success formula for yuzu product development | The process from planning to sales

Do you know the success case of Umaji Village in Kochi Prefecture?

A tiny village of fewer than 1,000 people achieved annual sales of 3 billion yen with processed yuzu goods. Overcoming the crisis of a declining forestry industry, it accomplished a miraculous revival through product development that leveraged local resources. Behind this success was a strategy of meticulous product planning and channel development.

Yuzu is one of Japan's representative fragrant-tart citrus fruits, grown mainly in the Shikoku region. Kochi, Tokushima, and Ehime prefectures in particular are major growing areas; hardy against winter cold, yuzu reaches its harvest in November and December. It has the characteristic that juice, peel, and seeds can all be used, with wide-ranging applications from food to cosmetics.

This article explains in detail the formula for successful yuzu product development, from the planning stage through to sales, with real examples. It offers concrete hints for those aiming at regional revitalization and those involved in new product development.

Points to Nail Down in the Planning Stage of Yuzu Product Development

Assessing Yuzu's Potential as a Local Resource

The first step in product development is deeply understanding the ingredient's characteristics. Yuzu is rich in aroma components—limonene, citral, eugenol, and vanillin—and a relaxing effect can be expected. It's also high in functional food components such as β-cryptoxanthin and nomilin, making it well suited to health-conscious product development.

Umaji Village began growing yuzu in 1963, but at first faced oversupply within the prefecture. However, this challenge became the trigger for a new strategy of developing channels outside the prefecture. Rediscovering the value of a local resource and asserting its uniqueness became the key to success.

Food-Loss Reduction and Value Creation Through Using Unused Resources

In yuzu juice production, the residue such as peel and seeds left after pressing accounts for half the yield. This disposal cost is a major burden for producers. However, that very residue holds the potential to become a treasure trove of new value.

In fact, cosmetics development using oil extracted from yuzu seeds has met with success. Utena Co., Ltd.'s "yuzu oil" series upcycled yuzu seeds that would otherwise have been discarded, surpassing a cumulative 7.2 million units shipped. This series won the Consumer Judges' Award at the "Social Products Award 2025," achieving both reduced environmental impact and regional revitalization.

Clarifying the Product Concept and Differentiation Strategy

Umaji Village Agricultural Cooperative put forward the clear concept of "selling the countryside." In competition with major companies, it differentiated itself not only through product strength but by conveying the region's story and values. Product names like "the yuzu drink 'Gokkun Umajimura'" and "the ponzu soy sauce 'Yuzu no Mura'" also express love for the region.

By developing them as processed goods, cultivation in line with organic methods became possible, offering consumers reassurance over appearance. With a lineup of about 70 products, it has expanded beyond food into cosmetics and body oils.

A Practical Approach to the Product Development Process

Building Scientific Grounding Through Industry-Academia Collaboration

商品の信頼性を高めるには、科学的エビデンスが不可欠です。城西大学では8年間にわたるゆず研究を通じて、ゆず果実ホールペーストの成分特徴と機能性を解明しました。研究では、機能性に関する知見が得られ、これらの成果が商品開発に活かされています。

In joint research between Tokyo University of Technology and POLA Inc., the mechanism by which yuzu "sanou" (juice sacs) extract acts on the stratum corneum was verified using a three-dimensional skin model. Improved flexibility of the stratum corneum through a reduction in desmoglein 1 was scientifically demonstrated, providing grounding that raises the product's added value.

A Development Cycle of Repeated Prototyping and Refinement

In Josai University's research, turning the yuzu peel and seed coat into a paste took several years. At first the bitterness was strong and commercialization was difficult, but by reframing the bitterness as a characteristic, they succeeded in developing pound cake and jelly themed around being "a little bitter."

In the development of Calbee's "Kata-age Potato: yuzu-scented sea bream dashi flavor," members of the fan site "Kata-age Potato Support Club" and the production team co-created together. Reflecting the tasting-session opinion "I want to taste the sea bream dashi first and the yuzu in the aftertaste," they repeatedly refined it so the yuzu is felt in the second half. In this way, a development process that incorporates consumers' voices raises a product's completeness.

Building the Package Design and Product Story

A product's appearance greatly influences the desire to buy. For the "Kata-age Potato" co-creation product, they created three package-design proposals based on illustrations made by support-club members and decided the final design by a runoff vote. A consumer-participatory development process generates attachment to the product and also leads to word-of-mouth spread after launch.

Umaji Village's products are characterized by storytelling that puts "local pride" front and center. The story of a village facing the challenge of population decline that achieved a revival by leveraging local resources evokes consumer empathy and raises brand value.

Strategies for Channel Development and Market Expansion

From Steady Channel Development to Nationwide Rollout

Umaji Village Agricultural Cooperative began developing channels outside the prefecture around 1975. At the time, yuzu wasn't widely recognized nationwide, and being asked "What's yuzu?" was not unusual. Even so, after years of steadily introducing products at department store trade fairs and events, buyers began sending word that they "wanted more," and the mail-order business got its start.

Today, mail order accounts for 30–40% of sales and has become a stable revenue source. The accumulation of steady effort led to the result of 3 billion yen in annual sales.

Securing and Deploying Diverse Sales Channels

The "yuzu oil" series is sold at drugstores and supermarkets nationwide, and from November 18, 2024, it has been on advance sale at convenience stores as well. Securing diverse sales channels increases points of contact with consumers and leads to greater awareness.

Sustainable initiatives through cooperation with local governments and drugstores are also highly regarded. Through a comprehensive partnership agreement with Kitagawa Village in Kochi Prefecture, it supports yuzu farmers and provides learning support for children, strengthening ties with the local community.

Building Online Sales and a Customer Community

In the digital age, online sales are indispensable. Umaji Village Agricultural Cooperative's mail-order business started with letters from customers as the trigger. Valuing direct communication with customers, it has built a mechanism for increasing repeat buyers.

By forming a fan community, as with Calbee's "Kata-age Potato Support Club," you can heighten participation in product development and improve brand loyalty. Launching one co-creation product each year since 2018, they have rolled out 7 products so far.

Sustainable Product Development Learned from Success Cases

Regional Revitalization and Corporate Social Responsibility

Yuzu product development is not merely a business but a means of regional revitalization. In Umaji Village, the yuzu industry creates jobs and plays a role in stemming population outflow. Efforts to create economic value while leveraging local resources and reducing environmental impact contribute to building a sustainable society.

The "yuzu oil" series also puts effort into educating the next generation through a project to co-develop cosmetics with children. Activities like these not only fulfill corporate social responsibility but also have the power to prompt changes in consumer behavior.

New Value Creation Through Upcycling

Upcycling, which turns waste into resources, achieves solving environmental problems and creating economic value at the same time. By using unused resources such as yuzu seeds and peel, you can reduce food loss and open up new product categories.

Drying and powdering technology enables long-term storage while preserving yuzu's aroma.Dried yuzu peelcan be used easily in clear soups, udon, baked sweets, and more, andYuzu powderis used widely as an ingredient for confectionery, drinks, and cosmetics. In the field of OEM production too, development of products such as herbal teas, soups, and dressings is advancing.

Ongoing Innovation and Expanding the Product Line

The market environment is always changing, and ongoing innovation is required. Umaji Village Agricultural Cooperative rolls out about 70 products, with staff putting their heads together to come up with ideas. With the resolve that "we won't lose to major companies on product strength," they focus on developing new products.

Recognition has spread overseas as "Yuzu" as well, and demand is rising alongside the washoku boom. With potential to spread across markets at home and abroad, yuzu is a versatile ingredient well suited to product-making that leverages aroma, color, and nutritional value.

Summary: Creating the Future of Region and Enterprise Through Yuzu Product Development

Success in yuzu product development requires assessing the value of local resources, using unused resources, and product-making grounded in scientific evidence. As the cases of Umaji Village and the "yuzu oil" series show, steady channel development and communication with customers bring long-term success.

In the planning stage, it's important to deeply understand the ingredient's characteristics and build a clear concept and differentiation strategy. In the development process, repeating prototyping and refinement that incorporates scientific verification through industry-academia collaboration and consumers' voices raises a product's completeness. In channel development, securing diverse channels and building online sales and a fan community enables sustained growth.

Yuzu product development is a sustainable business model that achieves both regional revitalization and environmental protection. Through new value creation via upcycling and ongoing innovation, you can open up the future of region and enterprise. Why not take on product development that leverages local resources and create social value yourself?
