The Rinnai Group develops gas burners, electric valves, and other functional components and products, deploying its strengths in combustion technology, heat transfer technology, fluid technology, IoT technology, and electronic control technology. Our water heaters provide high-efficiency hot water delivery, and our kitchen appliances feature automatic cooking functions. We strive to create value that improves the quality of life of our customers and contributes to the environment.
Our Research & Development Headquarters has designated areas that link fundamental technologies to the value we provide as the "Rinnai Innovation Circle," and our mission is to expand the boundaries of this circle through innovation.
In addition to conventional gas water heaters, we aim to provide bathing experiences that foster enhanced physical and mental health and suit individual preferences—experiences that give people with peace of mind and make them want to bathe every day.

In the kitchen space, we aim to help people save time in their lives through such products as automatic cookers with sensor-based heat controls and dishwasher/dryers with excellent cleaning performance.
