Marie Kondo is a Japanese organizing consultant, author, and television presenter who rose to international prominence with her distinctive philosophy of decluttering and tidying. Born on October 9, 1984, in Osaka, Japan, she developed an interest in organizing from a young age, reportedly spending her childhood reorganizing her family's home. Her method, often referred to as the KonMari Method, centers on the principle of keeping only items that "spark joy," a concept that has resonated with millions of people worldwide.

Kondo authored four books on the subject of organizing, which have collectively sold millions of copies across the globe. Her breakthrough publication, The Life-Changing Magic of Tidying Up, released in 2011, became a bestseller in Japan and later in Europe. The book was published in the United States in 2014 and has since been translated into more than 30 languages, making her a household name far beyond her native Japan. Her follow-up works continued to expand her reach, cementing her status as a leading voice in the home organization space.

In recognition of her cultural impact, Kondo was named to the TIME 100 list of the world's most influential people in 2015. Her influence expanded further with the release of the Netflix series Tidying Up with Marie Kondo in 2019, which brought her methods to a global streaming audience and earned her a nomination for the Primetime Emmy Award for Outstanding Host for a Reality or Competition Program. That same year, she launched an online store called KonMari, offering curated home goods and organizing products aligned with her philosophy.

Kondo is married to Kawahara Takumi, and the couple have children together. Her personal life has occasionally been featured in her public work, including reflections on how parenthood has influenced her approach to tidying. In August 2021, Netflix released a follow-up series, Sparking Joy with Marie Kondo, which explored the emotional and community dimensions of her work. Through her books, television appearances, and business ventures, Kondo has built a lasting legacy as one of the most recognized figures in the world of home organization and mindful living.
