Marie Kondo may be petite—4 feet, 7 inches—but she packs a real punch.

That became clear when the Japanese organization wizard’s 2011 book, The Life-Changing Magic of Tidying Up, became an international bestseller. Now she’s gone viral once more, thanks to Tidying Up with Marie Kondo, a TV series on Netflix.

Her “KonMari Method” of decluttering is mercilessly precise yet oddly poetic (you keep the items—and only those—that “spark joy,” then thank the others before tossing them out).

Kondo, 34, lives in Los Angeles with her husband and two daughters. Speaking through an interpreter, Kondo describes the five items in her home that, yes, spark joy.

A Treasure From Childhood

Fear not—the KonMari Method allows for nostalgia. Kondo demonstrates that old mementos can still serve a function, sometimes when used in new ways. “I received this sewing box for Christmas when I was a little girl,” she recalls. “It’s in my bedroom—near my vanity. I now use it to store makeup, so I get to experience the joy it brings me every day.”

Books with purpose

“I have several notebooks, each for a different purpose: one for ideas, one for dreams, one for problem solving, etc.,” Kondo says. “They’re located at the end of my bookshelf in the hallway, and I carry them with me in my purse as needed.”

A New Must-Have

“Rose water is my recent discovery. It has anti-inflammatory properties and the scent is sublime,” she says. “I keep a bottle in my bathroom and I use it primarily as a facial toner.”

Crystal Clear

“I admire crystals for their purification properties as well as their exquisite beauty,” Kondo says. Spiritual charms, talismans, and statues often wind up tucked away in a box or drawer, but Kondo recommends making a “personal altar” of such items in a corner or on a bookshelf.

Gratitude from the Ground Up

“I love to wear these specific socks around the house because they keep my toes warm,” she says. And, oh yes, in case you had any doubts: “My socks are folded and rest comfortably in their designated dresser drawer.”
