About the owner: Earth
Earth is a publicly listed company headquartered in Tokyo, Japan, founded in 1892. Brandtree records 9 brands under its control, and it is listed as TSE: 4985.
Earth Corporation is a Japanese household insecticide, pest-control, bath-additive and oral-care maker listed on the Tokyo Stock Exchange Prime Market (code 4985). Its company profile gives a founding date of 1 April 1892 in Osaka by Hidezo Kimura and an establishment date of 26 August 1925 (as Kimura Pharmaceuticals; renamed Earth Chemical in 1964). Its Integrated Report 2024 says the Otsuka Group took a capital participation in 1970, and the shareholder table there lists Otsuka Pharmaceutical (9.94%), Otsuka Pharmaceutical Factory (8.80%) and Otsuka Chemical (1.80%) among its top ten holders, but Earth remains a separately listed company. Earth's brand page also shows oral-care brands (Shumitect, Polident, Polygrip, Biotene, Aquafresh) that were not added here because the documents opened do not say whether Earth owns them or sells them under licence; the 2024 report says only that Earth Corporation had sales collaboration with Block Drug (1996) and GlaxoSmithKline (2002).
🇯🇵 Mondahmin and other Japanese brands
Brandtree records a controlling owner for 437 brands that began in Japan. 21 of them (5%) are now controlled by a company headquartered in another country; Mondahmin is not one of them.
