Zojirushi vacuum flask

Zojirushi Corporation is a prestigious Japanese manufacturer known globally for its high-quality vacuum insulated bottles and advanced kitchen appliances like rice cookers and breadmakers. Founded in 1918 as the Ishikawa Brothers Trading Company, it adopted the Zojirushi name—which incorporates the elephant ('Zo') as a symbol of strength and familial bond—in 1961.

While the brand maintains its design and engineering roots in Japan, its manufacturing footprint is global. The majority of its vacuum flasks and stainless steel bottles are produced in Thailand, while high-end electronics are often manufactured in Japan and other product lines are made in China. The company remains an independent Japanese entity, listed on the Tokyo Stock Exchange, and is widely regarded as a leader in thermal insulation technology.
