Kojima, the birthplace of domestically produced jeans.
Our company, Betty Smith, was founded here in 1962 as Japan's first manufacturer of women's jeans.
Since then, the company has built its position as a leading manufacturer of women's jeans, while also founding the Eco Betty brand of accessories made from recycled jeans fabric in 2002. The following year, it opened the Jeans Museum.
In the same year, we started offering fully custom-made jeans ("Custom-made Jeans"), and for the past half century we have continued to present new values to the jeans industry.
Our corporate attitude of always taking on new challenges will not change in the future. Betty Smith has defined the "creation of a jeans culture in Japan" as our corporate mission, and we hope to continue to actively create new values for the next half century.
