The Birth of Rinnai

Rinnai uses reliable technologies to create "heat and lifestyles" while embracing the spirit of its foundation

One November day in 1918, Hidejiro Naito stood mesmerized in front of a shop making imagawayaki, a traditional Japanese bun usually filled with adzuki bean paste.

He was intrigued by the blue flame that came from the imported oil-burning cooking stove used to cook the imagawayaki. Keen to try his hand at making a similar stove, Hidejiro convinced the shop owner to part with the stove. Using it as a model, Hidejiro subsequently developed a petroleum-fuelled stove, heralding the origin of the business we know today.

Two years later, in 1920, Hidejiro left his job at Nagoya Gas (currently Toho Gas Co., Ltd.). Together with Kanekichi Hayashi, a childhood friend who lived in the same dormitory, they established Rinnai & Co., the forerunner of today's Rinnai Corporation. The company name was coined from characters in the two men's last names ("Rin" is another way of reading Hayashi, and "Nai" comes from "Naito").

Thus began nearly a century of developing the latest heat-energy appliances. Over the years, Rinnai's products slowly transformed Japanese lifestyles as the nation continued on its path to modernization.

From its origins through to the present day, Rinnai has been guided by its Corporate Mission, which is "to use heat to provide society with comfortable lifestyles."

The ethos of contributing to society—evident in the early catalog for Rinnai's original, petroleum-fuelled stove—has endured unchanged through to the present day.

Brand Movie

 

Quality is our destiney

Rinnai Corporation has adopted "Quality is our destiny" as its basic quality philisophy and strives to infuse the idea of "Customer first", "Product safety" and "Legal compliance" throughout Rinnai group, and stabilize the culture of product safety.

Manufacturing

Since our founding, we have used heat to provide people with healthy and comfortable lives. However, even a small defect in heating equipment can cause a major accident.

As a comprehensive manufacturer of heat and energy equipment, we have rigorously practiced "quality-oriented manufacturing" at our R&D and production sites, placing top priority on the safety and security of our customers. Committed to engaging in the best manufacturing practices, we focus on the following three things.

 

Self-sufficiency

We emphasize in-house production technologies in order to improve quality.

 

Integrated production

We integrate all processes—from design to processing, assembly, inspection, and shipping—in order to ensure high quality.

 

Mechanisms to support safety and security

Reflecting our belief that the best manufacturing derives from employee skills and optimal environments, we strive to improve education and work spaces.

 

Pursuing "self-sufficiency" to improve quality

At Rinnai, we are committed to handling all stages independently, including the design of processing technologies necessary for production. We make our own dedicated equipment and tools to ensure reliable manufacture of safe and high-quality products. We believe this is key to raising our manufacturing standards.

Moreover, self-sufficiency enables us to accumulate and pass on technologies and skills, leading to creation of better products.

 

1. Prototypes

We draw on the skills of artisans to ensure greatest accuracy of prototype design. We also actively work on new prototyping methods to provide a smooth transition to mass production.

 

 

2. Molds

We are constantly pursuing better mold technologies, which are very challenging, and using the results of these activities to reduce costs.

 

 

3. Equipment

We are committed to a wide range of in-house automation technologies, from processing of parts to shipping of final products, and the competitiveness of our manufacturing sites is increasing as a result.

 

 

4. Software

We are developing original software that fully addresses the requirements of rapidly changing manufacturing sites, so we can quickly respond to requests from each site.

 

 

 

Integrated production system ensure high quality

We make high-quality products because we adopt an integrated production system at our own factories. This covers all processes, from processing to assembly, inspection, packaging, and shipping. 

We also respond flexibly to market needs because we can handle mixed production of multiple items, and we can flexibly and quickly make the required products only when needed. This includes our ability to handle express shipments and large-volume orders.

 

 

 

 

 

 

Important control-relared parts, such as gas control units, are developed in-house and manufactured by Rinnai Group companies.

Aiming for zero defects across entire Rinnai Group, we work as one to manufacture safe and secure products.
