Senio is a relatively new player amongst the established Okayama based brands. But they are not new to the Denim industry by any means. Owner, Kohji Niwa, had been producing OEM denim for a hand full of renowned Japanese brands for 13 years before he started Senio in 2007. Up until earlier this year, he was selling his jeans by word of mouth to friends and family. Now most of his sales are done through the store front he has established in Kojima and online exclusively at OkayamaDenim.com.
