Daisuke Yosumi was born near Osaka in 1970. He was a producer at Sony Music in Japan. At 34, he was headhunted to lead the producer division at Warner Music Japan. He oversaw both production and promotion, and produced ten million-sellers before moving to New Zealand in 2010 to fulfil a long-held dream. The original Japanese edition of Let Go sparked a nationwide minimalist boom.

He mastered the art of 'letting go' through three radical life stages: his difficult school years, the
corporate battlefield, and now a self-sufficient life free from the pressures of time and money in New Zealand, where he lives with his family. A pioneer of Japan's digital nomad and trekking movements, he is the first Japanese ambassador for both Greenpeace Japan and Fairtrade Japan. He also leads LifestyleDesign.Camp, an online community school for post-capitalist living.
