  About Swans

“Founded on the corporate principle of “creating a culture promoting a high quality of life for people as our contribution to society”, YAMAMOTO KOGAKU has been developing protective eyewear products since starting business in 1911.”

“Through our ceaseless research of new technologies based on our proprietary light-controlling techniques, YAMAMOTO KOGAKU has turned out two brands, YAMAMOTO and SWANS, which protect working people’s safety and offer the best sports gear for athletes, respectively. The diverse range of glasses and lenses that we have offered to the world has supported people’s lives for more than a century.”
