Since the introduction of its first glass-lined vacuum bottle, Zojirushi has continued to pursue the preservation of deliciousness of food.

Japan’s staple food rice is no exception. The pursuit of keeping rice warm while maintaining its deliciousness has led to the development of groundbreaking electric cooking appliances.In 1970, Zojirushi incorporated a thermistor (semiconductor element) with the heating technology that keeps rice warm to launch the world’s first electric rice warmer with optimum temperature control enabled.This invention marked the start of Zojirushi’s electric cooking appliance business.

In 1974, Zojirushi launched an electric rice cooker that automatically kept rice warm.Since then, Zojirushi’s pursuit of the science of “deliciousness” has greatly advanced rice cookers.

Moreover, Zojirushi engaged in product development initiatives that respond to customer needs.For example, Zojirushi’s sophisticated technologies have revolutionized the design of electric air pots and led to the market launch of highly energy-efficient electric air pots whose interior designs are similar to thermal carafes with vacuum insulation.

Zojirushi’s product line has expanded to products such as hot plates, toaster ovens, coffee makers, and oven ranges.Technology that brings out the deliciousness of the ingredients themselves, usability that meets the users’ needs such as being time-saving, labor-saving and energy-saving, and a smart and sophisticated design required for an everyday use tool.Zojirushi’s high-quality, high-performance products pursue these ideals required for cooking appliances, and have earned a reputation as products that bring joy to the dining experience.

Zojirushi has studied the properties of heat since its founding, maintaining the temperature of foods and beverages, ensuring that hot foods and beverages remain hot and cold foods and beverages remain cold.One could say that Zojirushi is the leading global authority in temperature retention technologies. By pursuing greater efficiency and usability, Zojirushi has developed various innovative features including the air pot that dispenses beverages with the push of a button.We have changed the norm of thermal pots one after another. Vacuum bottles were made of glass, but to solve breakage issues, Zojirushi launched a vacuum bottle made of stainless steel.Zojirushi accomplished this feat by leveraging the processing and insulation technologies for conventional glass vacuum bottles that it had accumulated over the years.Then, in 1998, Zojirushi succeeded in developing stainless bottles that featured a vacuum insulation layer a mere millimeter thick with the same durability of traditional models using cutting-edge stainless steel processing technologies.

Zojirushi has earned accolades for its high-performance, lightweight, compact stainless steel vacuum bottles, and its technologies are embodied in stainless steel food jars, tumblers, and other products.In addition, Zojirushi is making strides in marketing insulated containers for use outside of the home, including drink dispensers commonly used in hotels and restaurants.

With heat and cold retention technology at its base, Zojirushi looks at preservation and cooking methods from various angles, and has been proposing products centered around food.To pursue a more comfortable and fulfilling life, we have been expanding our horizons and working on the development of high-quality, high-performance products that are closely related to our daily lives.

Zojirushi is working to meet consumers’ needs by developing a wide range of products.We have created humidifiers that utilize technologies used in electric air pots, bedding dryers without hoses, and other unique products that leverage our wealth of experience in developing household-use products through a process that focuses on development from the consumers’ point of view.
