I'm Yusei, a product designer based in Ehime, Japan. I've worked across both B2B and B2C companies, contributing to product design in a range of contexts. Most recently, I was at Back Market — a French-founded online marketplace for refurbished electronics — where I contributed to several growth initiatives. I led the localization for the Japan market, helping make refurbished smartphones and other electronic devices a natural and compelling choice for people in Japan. What drives me is the belief that good design can bring small but meaningful change to people's everyday lives. Outside of work, my love for vintage clothing and gadgets keeps my design sensibility sharp and constantly evolving.
