A significant growth in demand for plant-based proteins is being noted, with greater health and environmental consciousness among consumers in Japan, and rice protein is perfectly poised for this trend on account of its sustainability and hypoallergenic features. The focus on functional foods is also gaining momentum, as consumers look for products that offer added health benefits. Rice protein's nutritional value and potential health benefits make it an attractive ingredient for incorporation into functional foods and beverages.

For instance, as per the USDA, in 2022, the total value of all retail food and beverage sales in Japan had reached $327 billion. Supermarkets continue to provide the majority of sales in the retail food market, accounting for 35 percent, while convenience stores, drugstores, and internet sales of food and beverages account for the rest of the market. Moreover, the retail industry in Japan has remained stable even with the continued strength of the U.S. dollar vs. the Japanese yen. To drive demand, retailers have strategically targeted the younger generation who seek easy-to-prepare, frozen, and ready-to-eat foods.

Japan Rice Protein Market Growth Drivers:

• The rising geriatric population is accelerating the adoption of rice protein in Japan

Japan's rapidly aging population significantly impacts the demand for rice protein. As people age, maintaining muscle mass becomes crucial to prevent sarcopenia, age-related muscle loss. Rice protein, being a complete protein source, provides the essential amino acids needed for muscle synthesis and repair. The population of Japan is aging, with almost 30 percent of the population over age sixty-five in 2021. The government of Japan projects this number to grow to over 35 percent by 2040. Healthcare costs are projected to spiral upward, given the higher costs associated with elderly populations.

Further, the Cabinet Office projects that, in 2045, 50.1 percent of the residents of Akita Prefecture will be older than sixty-five years of age, and 46.8 percent of Aomori Prefecture's residents, whereas Tokyo and Osaka will each reach 30 percent and 36 percent, respectively.

Japan Rice Protein Market Key Segments:

• By source, organic rice protein is expected to witness significant growth in the Japan Rice Protein market

Organic rice protein is gaining wider acceptance due to rising health benefits, environmental sustainability, and also due to the lack of synthetic chemicals and genetically modified organisms (GMOs). The growth is supported by the growing consumerism for health and wellness, where people actively look to consume whole-plant food sources and adequate protein supplements for muscle recovery and overall health. This clean label trend, in turn, has driven growth in the organic rice protein market owing to the demand for organic products by consumers.

Moreover, in Japan, organic rice protein is included in an ever-expanding catalog of products produced by Japanese manufacturers. The versatility of this protein source allows incorporation into a wide range of formulations in Japan, inclusive of snacks, beverages, and dietary supplements. Its flexibility responds to the changing preferences in Japan for alternative protein sources, whilst moving away from traditional sources. Manufacturers have quickly exploited this trend and introduced products that incorporate flavors popular with the Japanese while adhering to organic and sustainable manufacturing practices.

Further, organic brown rice protein is increasingly being utilized by Japanese manufacturers in several products. The versatility of organic rice protein makes it an ideal ingredient for a wide range of products, including snacks, beverages, and dietary supplements. This adaptability helps meet the evolving tastes and preferences of Japanese consumers, who are increasingly open to alternative protein sources beyond traditional options.

Additionally, Japan’s organic rice protein market continues to grow in response to its consumers’ health and wellness needs. For instance, Roquette offers NUTRALYS® rice protein, a safe and familiar source of plant protein, suitable in combination with the NUTRALYS® pea protein for taking up active, holistic health through a complete vegan protein supplement. Rice protein is healthy compared to dairy and meat-based proteins and perfectly complements plant-based foods and beverages, promoting an active lifestyle.

• By end-user industry, food & beverages is expected to witness significant growth in the Japanese rice protein market

The food and beverage industry is witnessing a high demand in the Japanese rice protein market. Rice protein is acknowledged as one of the highest sources of plant protein ingredients across a wide array of food and beverage applications. This includes its extensive use as an ingredient in vegetarian meat substitutes, dairy-free products, baked products, and nutritional supplements.

Moreover, the food & beverages sector is also rising due to the ongoing change in consumer selection shifting from highly processed foods to healthier ones. Furthermore, the demand for functional foods has been driving the opportunity for myriad plant protein ingredients, rice proteins in particular, across a handful of applications, mainly in the food and beverage space. With the rising concerns for environmental sustainability, general health awareness, ethical positions, and animal rights concerns, consumer demand for plant-based diets continues to grow. For instance, in 2022, the total packaged food sales in Japan with high-protein ingredients were US$589.1 million, whereas plant-based products amounted to US$948.2 million.

Further, in January 2023, Roquette, a global leader in plant-based ingredients and a pioneer in plant proteins, invested in DAIZ Inc., a Japanese food technology startup that has developed breakthrough technology that uses plant seed germination combined with an extrusion process to improve texture, flavor, and nutritional profile in plant-based foods. This collaboration will enable Roquette and DAIZ to continue achieving their ambitious growth goals while also meeting rising global demand for innovative and sustainable plant-based ingredients that combine great taste and high nutritional value. Additionally, the support by the Japanese government in the rice farming and rural development projects will boost market growth. The vast expanse of arable land and its conducive climate are favorable for rice farmers practicing organic rice farming on a larger scale, making the country a major player in influencing industry growth.

• Protein isolates are witnessing rapid market growth

Protein Isolates, characterized by their high protein content (typically over 80%) and low levels of carbohydrates and fats, lead the Japanese rice protein market.

Japan’s increasing adoption of vegan and vegetarian diets, driven by health, environmental, and ethical concerns, boosts demand for rice protein isolates. With approximately 5% of Japan’s population identifying as vegetarian or vegan in 2024, isolates are favored for their plant-based origin and hypoallergenic nature, appealing to consumers with lactose intolerance or soy allergies.

The sports nutrition sector in Japan, valued at USD 1.2 billion in 2024, is increasingly incorporating rice protein isolates into protein powders, bars, and ready-to-drink beverages. Their high protein purity and clean-label appeal drive their use in premium products. For instance, Otsuka Corporation’s 2024 launch of vegan protein drinks featuring rice protein isolates targets fitness enthusiasts and health-conscious consumers.

Japanese consumers also prioritize clean-label and non-GMO products, and rice protein isolates meet these preferences due to their minimal processing and natural sourcing. Axiom Foods’ Oryzatein, expanded in Japan in 2023, emphasizes organic and non-GMO certifications, driving its adoption in functional foods and supplements. For instance, Axiom Foods scaled up its Oryzatein rice protein isolate production for Japan, focusing on organic and non-GMO offerings for sports nutrition and functional foods. Otsuka launched a line of vegan protein drinks using rice protein isolates, targeting Japan’s growing health and wellness market.
