Okamoto Industries Inc

A Japanese maker of rubber and plastic goods, Okamoto Industries is best known worldwide for its condoms, sold under thin latex and polyurethane lines like the 001 and 002 series, alongside automotive materials and industrial products. It traces its start to 1934 in Tokyo, when founder Minosuke Okamoto set up the Okamoto Rubber Plant to research and make natural-latex condoms, later merging with other rubber firms to form today's company. Fun fact: the brand got its name from that founder, so a household name in sexual wellness began as one man's latex workshop.
