Fumio Sasaki is a Japanese author and co-editor-in-chief at Wani Books, based in Tokyo. Known for his embrace of minimalism, Sasaki has gained international recognition through his first book, Goodbye, Things. He lives in a 20-square-meter apartment furnished with only the essentials—a desk, a folding mattress, and a wooden box—embodying the minimalist lifestyle he advocates. Sasaki’s approach to minimalism is deeply personal, reflecting his journey from stress and constant comparison to others, to a newfound sense of peace and contentment.

Sasaki’s writing focuses not only on decluttering one’s physical space but also on how minimalism can transform mental and emotional well-being. His work has resonated with readers around the world, with Goodbye, Things selling over 200,000 copies in Japan alone and being translated into multiple languages. Through his books and online presence, Sasaki continues to inspire people to simplify their lives and find happiness in less.
