Historical Foundation

In the Kamakura period, a priest named Kakushin at Kokoku Temple in Yura, Kishu (now Hidaka County, Wakayama Prefecture) accidentally created a precursor to soy sauce while teaching villagers to make Keizanji Miso, a method from China. This mistake led to the creation of something similar to today's Tamari Soy Sauce. YAMASA, located in Chiba Prefecture, benefits from the collision of cold and warm ocean currents, creating a warm, humid environment ideal for brewing soy sauce year-round. This enabled the production of highly fragrant, brightly colored, high-quality soy sauce. Choshi's location at the mouth of the Tone River, with Japan's largest watershed and favorable climate, was key to YAMASA's early success.

Yamasa was incorporated in 1928, and it’s notable milestones include establishing Japan's first soy sauce laboratory in 1899, and creating YAMASA CORPORATION U.S.A. in 1992. The company continues to innovate and expand globally with recent ventures like YAMASA EUROPE B.V. and YAMASA ASIA OCEANIA CO., LTD.

Modernization and Technology

Mr. Goryou Hamaguchi, the seventh-generation leader, secured government recognition for Yamasa's superior soy sauce quality. Under the leadership of the 10th-generation Gihei, Yamasa embraced modernization, integrating innovative agricultural and industrial technologies.

Diversification and Global Expansion

In 1983, the current president Mr. Michio Hamaguchi (12th-generation head), spearheaded Yamasa's diversification into general seasoning and expanded its global footprint. The company's commitment to continuous innovation led to the development of new products and entry into overseas markets, including the United States and Thailand.

Corporate Philosophy and Innovation

Yamasa's corporate philosophy emphasizes originality, differentiation, and societal contribution. Its Code of Conduct focuses on product safety, compliance, fairness, and environmental responsibility, reflecting the legacy of Goryou Hamaguchi's dedication to social welfare.

Adapting to Market Changes

Yamasa's management strategy centers on "Continuous Innovation." To address evolving consumer preferences, Yamasa established the New Product Planning Section and the Product Development Section. These units have developed products like "Shinmi Shoyu" and "Sashimi Shoyu," (types of soy sauce) catering to contemporary tastes while maintaining traditional quality. In 1992, Yamasa introduced the first organic soy sauce in the industry, showcasing its commitment to sustainability.

Customized Solutions for Food Industry

Yamasa's "Original Recipe Manufacturing" system caters to the expanding market for food processing and food service. This system allows for customized product development, supported by a state-of-the-art factory capable of handling diverse production needs. Sales engineers with food science expertise collaborate with clients to create innovative menu items and flavors.

Global Strategy and Challenges

Yamasa's global expansion began in the Edo period (1603-1868), with soy sauce exported to Europe through the Netherlands. By the 1970s, soy sauce gained popularity in the U.S. Yamasa's overseas production strategy, bolstered by facilities in the U.S., aligns with the principle of "Produce locally for local markets." The company now faces the challenge of developing sales engineers proficient in foreign languages and capable of meeting diverse international demands.

Pharmaceutical Innovations

Between 1955-1957, Akira Kuninaka (Researcher) of Yamasa Research Institute discovered the umami (taste) component 5′-inosinic acid and identified a microbial enzyme that produces it by breaking down yeast RNA. Leveraging this, company began producing 5′-inosinic acid and 5′-guanylic acid industrially. These compounds, when combined with monosodium glutamate, greatly enhance the umami taste. Kuninaka's work earned him the Imperial Invention Award in 1964. This innovation paved the way for Yamasa to develop nucleic acid-related compounds essential for life and vital activities, used in pharmaceuticals, food enhancers, and diagnostics. Renowned for their quality and innovation, Yamasa's pharmaceutical products are considered world-class.

Sustaining Long-Term Prosperity

Mr. Michio Hamaguchi's leadership emphasizes long-term prosperity over short-term gains. He highlights the importance of adapting to environmental changes while maintaining the core business. This approach, coupled with a commitment to innovation, has ensured Yamasa's resilience over centuries.

Leadership Transition and Future Outlook

As Yamasa prepares for leadership transition, the company's commitment to long-term prosperity remains steadfast. The appointment of Mr. Naoyuki Ishibashi current president (Michio’s Nephew), a visionary leader with a track record of success, reflects Yamasa's readiness to adapt and thrive in an ever-changing business landscape.

Yamasa Corporation's journey exemplifies resilience, innovation, and adaptability. Through centuries of challenges and transformations, the company has remained true to its core values while embracing change. As it looks to the future, Yamasa is poised to continue its legacy of excellence in the global market, driven by a commitment to quality, innovation, and societal impact.
