Transforming Kitchenware with Auto Parts Forging Technology

Yamako Co., Ltd., a company based in Higashi-Osaka known for its precise forging technology used in automotive parts, has unveiled a new kitchen brand named 'TANZO'. This brand is centered around the concept of creating 'durable iron cookware that can be used without hesitation'. It will make its debut at the 100th Tokyo International Gift Show, which is set to take place from September 3 to 5, 2025. The core of TANZO's offerings includes products that earned the Grand Prize at the 97th Gift Show LIFE×DESIGN Award in 2023, marking a significant milestone in their brand evolution.

The inception of TANZO was inspired by the founder, Etsuko Yamamoto, who found herself overwhelmed by the challenges of managing work and raising two children. She recognized that while the demand for authentic flavors surged during the pandemic, the cumbersome nature of traditional iron kitchen tools made them less accessible. This dilemma ignited a desire to leverage the company’s advanced technology to develop practical cookware that enhances everyday cooking without the burden of complexity.

The Birth of a Kitchen Revolution

From the heart of a forging factory utilized for manufacturing complex automotive parts, a revolutionary product has emerged, designed to transform your kitchen experience. The unique 'Air Stamp Hammer' exerts approximately 2000 tons of pressure on a block of iron heated to 1250℃, efficiently removing impurities and enhancing the purity of the iron to unprecedented levels. This innovative process, combining the raw power of the hammer and the expertise of skilled artisans known as the 'Hammer Men', has enabled the unprecedented forging of intricate culinary utensils that were previously deemed impossible.

Key Features of TANZO: A Culinary Science

1. Uncompromising Material Quality
TANZO utilizes the highest quality carbon steel available in Japan. By heating the iron to 1250℃ and repeatedly forging it under immense pressure, impurities are eliminated and the internal crystalline structure of the metal is refined, resulting in exceptional strength and durability. With no artificial coatings applied, users can confidently incorporate these tools into their daily cooking routines.



2. The Golden Ratio Thickness
After six years of relentless pursuit of the ideal balance between lightness and effective cooking, TANZO’s products achieve a golden proportion of thickness—3mm on the sides and 4mm on the base. This design ensures that enough heat is retained to cook food evenly, preventing sticking and preserving flavor without excessive effort.



3. Superior Thermal Conductivity and Heat Retention
Thanks to its high thermal conductivity, TANZO cookware allows for shorter cooking times with reduced heat, ensuring that the essence of the ingredients is captured. Even after the heat source is turned off, gentle residual warmth continues to cook the food, allowing for deliciousness to be maintained until the last bite.

A Commitment to Sustainability and Longevity

'TANZO' is not just about creating cooking tools; it champions a lifestyle that values durable, cherished possessions. Its cookware can be directly transferred to the dining table, serving as both a cooking instrument and a beautiful piece for any meal setting. By nurturing a single, reliable tool over the years, users can cultivate an attachment that aligns with a sustainable lifestyle—something that reflects a deeper, more essential form of living.
