Committed to manufacturing excellence through Kaizen

Japanese manufacturing is renowned for high levels of aesthetic and operational function. Many leading global brands in electrical and combustion technology are from Japan, such as Toyota, Nissan, Honda, and Sony, all of which incorporate the Kaizen and Kanban methodology into daily operations.



The term Kaizen has come to mean ‘continuous improvement’, with a focus on

implementing gradual and incremental changes that will produce long-term improvements in efficiency and quality. Kanban was invented by Toyota engineer Taiichi Ohno in the 1940s. The philosophy encourages continuous improvement by measuring project progress through visual Kanban

boards. It is also referred to as the ‘Just in Time’ system.


The creator of the Kanban framework maintains strong links to Rinnai and has had a discernible influence on Rinnai’s production system. Ohno visited Rinnai’s Japanese production plant and provided advice that led to Rinnai adopting lean manufacturing principles to enhance efficiency.


Rinnai products incorporate the best manufacturing techniques, ensuring robust product performance, extended warranties and cost effectiveness.
