Our History



For over 100 years, the successful brands that are part of LIXIL have combined the best of the past with a vision for the future.

LIXIL was born in 2011 through a merger of five of Japan's most successful building materials and housing companies, TOSTEM, INAX, Shin Nikkei, Sunwave, and TOEX. From the early 20th century, the founding fathers of our legacy companies ushered in an era of innovation and laid down the principles that would make LIXIL one of the most respected names in the Japanese building and housing industry. The global brands that are now a part of LIXIL also share a heritage of innovation that dates back to the 19th century.
