Spark Joy: An Illustrated Master Class on the Art of Organizing and Tidying Up

Spark Joy is the second book by Japanese tidying consultant Marie Kondo and serves as an illustrated companion to her first book, The Life-Changing Magic of Tidying Up. While the earlier work introduced the philosophy behind her approach, this volume provides detailed, practical instructions for readers who have already committed to what Kondo calls the KonMari Method, a system for organizing one's home by keeping only those possessions that "spark joy."

Kondo opens by establishing the book's central premise: Life begins only after one has put one's house in order. She stresses that tidying is not about indiscriminate discarding but about learning to identify and keep the things one truly loves. Only two skills are required: the ability to keep what sparks joy and discard the rest, and the ability to assign each kept item a permanent home and always return it there.

The book's foundation rests on six rules. First, commit to tidying. Second, envision an ideal lifestyle to anchor the process in personal aspiration. Third, finish discarding before organizing, because overstuffed storage cannot stay tidy. Fourth, tidy by category rather than by room, gathering every item from a single category throughout the house into one spot. Fifth, follow a prescribed order: clothes, books, papers, komono (a Japanese term Kondo uses throughout to mean miscellaneous household items), and sentimental items. This sequence progressively sharpens one's ability to detect joy, beginning with the easiest category and ending with the most emotionally difficult. Sixth, hold each item in both hands and ask whether it sparks joy, paying attention to the body's response.

Kondo then addresses how to hone one's sensitivity to joy. She distinguishes tidying from cleaning: Tidying deals with objects and demands decision-making, while cleaning deals with dirt and requires regular maintenance. For readers who struggle to identify what sparks joy, she recommends the "top three" exercise, in which one selects the three most joy-inducing items from a pile, using comparison to clarify feelings. She advises starting with tops when sorting clothing, since most people own enough of them to make meaningful comparisons, and suggests hugging uncertain items against one's chest. She declares the phrase "it might come in handy" taboo during a tidying marathon, arguing that substitutes always exist. At the same time, she acknowledges that joy is not limited to excitement; simple functionality or a sense of ease also qualifies. She clarifies that temporary clutter, which occurs when items are not returned to their assigned spots, differs fundamentally from true rebound, which occurs when items have no designated place at all. She shares the example of a client whose house featured books stacked on every stair and a bedroom buried in clothes, arguing that no matter how much clutter exists, the quantity is always finite.

Shifting from discarding to creating, Kondo warns against becoming a "discarding machine." The goal is not an empty house but one filled with beloved things. She rejects the popular advice of placing uncertain items in a box for a trial period, describing how her own attempt with this approach over two and a half years produced only guilt. Instead, she advocates keeping gray-zone items openly and treating them with full care, or discarding them outright. She identifies three elements of attraction in objects: innate beauty, love accumulated through care, and personal history. She recommends adding color to bare post-tidying homes through flowers or favorite objects and encourages readers to create a personal "power spot," a dedicated space filled only with things one loves.

Her storage philosophy centers on several principles. She advises treating all storage as temporary until discarding is complete and recommends grouping items by material, with cloth, paper, and electric as three main categories. She compares ideal drawer storage to a Japanese bento box, a traditional compartmentalized lunch, emphasizing close fit and visual appeal. She identifies four universal storage principles: folding anything soft, standing items upright, storing each category in one spot, and dividing storage space into square compartments. Her folding method mirrors origami: fold edges toward the center to form a rectangle, fold in half lengthwise, then fold again until the item can stand independently. For deciding where to store things, she establishes two rules: Use built-in storage first and store large items first, with the long-term goal of eliminating freestanding storage furniture.

The book's longest section constitutes a category-by-category encyclopedia. For clothes, the first and most foundational category, Kondo provides folding and storage instructions for every garment type, from tops and pants to socks, underwear, and bras. Closets should be organized with lighter items in upper drawers, heavier items below, and colors arranged in a light-to-dark gradation. She covers bags, accessories, and shoes, and advises letting children aged three and older choose their own joy-sparking items.

For books, she argues that once read, a book has been "experienced" and its content internalized; unread books should be discarded if they have gone unread long enough. For papers, her default position is to discard everything, keeping only those with a clear current purpose. She introduces the pending box, a container for papers requiring action, and addresses subcategories including course materials, warranties, manuals, and greeting cards.

The komono section covers dozens of subcategories, from stationery and electronics to skincare products, medicines, valuables, bedding, and stuffed toys. Kondo devotes extensive attention to kitchen komono, arguing that the ideal kitchen prioritizes ease of cleaning over ease of access. She recommends storing everything, including dish soap and sponges, inside cupboards and off counters. She warns against tidying the kitchen first, since it requires the most refined joy-detection skills. She also addresses bathroom and toilet-related storage, emphasizing the elimination of visual "noise" such as product labels and logos on everyday items.

For sentimental items, the final category, Kondo frames the process as putting one's past in order. She advises against sending sentimental items to parents' homes, where they create burdens, and covers subcategories including school memorabilia, mementos of past relationships, children's artwork, and letters. Photos constitute the absolute final step: One should remove them from albums, select only those that spark joy, and arrange the keepers in a new album by year.

Kondo also provides room-by-room guidance for shaping a joy-filled home. She recommends keeping the entranceway clear, making the living room a center of family life, prioritizing cleanliness in the kitchen, designing the bedroom as a recharging space with soft lighting, and keeping the bathroom uncluttered and naturally aromatic.

The concluding chapters explore the broader life changes that follow tidying. Kondo illustrates transformation through former clients: Mayumi, who went from describing herself as incapable of finishing anything to becoming Kondo's apprentice, and a client who, while sorting unsettled paperwork, recognized the ambiguity in her three-year relationship and gained the clarity to accept her boyfriend's marriage proposal. She advises readers to lead by example rather than criticize family members and acknowledges that some people are genuinely happier in clutter. Accepting differing values, she argues, is itself part of finishing the tidying process. She reflects that joy-sparking objects absorb precious memories, recounting a cherry blossom picnic during which her mother served pink amazake, a sweet fermented rice beverage, in blossom-patterned glasses. The experience revealed to Kondo that objects steeped in memories of time with loved ones carry deeper value than objects cherished in solitude.

In the epilogue, Kondo recounts giving tidying lessons to her own father, who had avoided discarding for a decade. Over two days, they worked through the prescribed category order, filling 20 bags and transforming his room into a bright, open space. In her afterword, she connects the KonMari Method to the Japanese concept of yaoyorozu no kami, the belief that gods reside in all things, and concludes with the idea of mono no aware, a term for the deep emotion evoked by awareness of transience. She argues that tidying sharpens one's capacity to feel this essence, leading to a deeper appreciation of possessions, relationships, and daily life.
