Marie Kondo’s “The Life-Changing Magic of Tidying Up” introduced millions of people to a Japanese approach to decluttering that is both systematic and deeply personal. The KonMari method is not about throwing things away until your home looks empty. It is about keeping only what sparks joy and treating your possessions with respect.
The method works because it is structured. You do not declutter by room, which leads to shuffling items around the house. You declutter by category, gathering every item of a type in one place and making decisions about all of them at once. Here is how to work through the five categories in the correct order.
Category One: Clothing
Clothes come first for a reason. They are the least emotionally charged category, which makes them the best place to build your decluttering muscle. Start by gathering every article of clothing you own. Every shirt, every pair of pants, every sock, every coat. Pile them on your bed. The visual impact of seeing everything you own in one place is often the motivation needed to begin.
The spark joy test is the core decision mechanism. Pick up each item one at a time and hold it in both hands. Does it spark joy? This is not a rational analysis of how often you wear it or what it cost. It is a felt response. Kondo describes joy as a little thrill, a sense of “yes” in your body when you touch something you love.
Items that spark joy stay. Items that do not get thanked and released. The thanking ritual feels awkward at first. Say “thank you for teaching me that I do not like this color” or “thank you for keeping me warm when I needed you.” The ritual acknowledges that the item served a purpose even if that purpose is complete.
Folding is the second pillar of the clothing category. Kondo’s folding method stores clothes vertically in drawers so you can see everything at a glance. Fold each item into a neat rectangle that stands on its edge. Shirts, pants, underwear, socks, all get the same treatment. Drawers become displays rather than piles.
Category Two: Books
Gather every book from every shelf, nightstand, and box in the house. Stack them on the floor. The pile will probably be larger than you expect.
The spark joy test applies here too, but with a specific instruction from Kondo: do not open the books. Opening a book triggers reading, which triggers the thought that you might want to read it someday. Keep the book closed, hold it, and sense whether it brings you joy.
Reference books, textbooks from school, unread bestsellers purchased years ago, books you read and did not enjoy, all face the test. Many people discover that they keep books not because the books themselves spark joy but because the idea of being a person who reads those books sparks joy. Separate the identity from the object. Keep the books you love and will revisit. Release the rest to libraries, friends, and used bookstores.
Category Three: Papers
Papers are the category most people dread, and Kondo addresses this by setting a strong default: discard everything. Her rule is that papers do not spark joy in the same way clothing and books do. The deciding factor for papers is whether they are required.
There are only three types of papers worth keeping. Papers you are actively using, such as bills to pay or forms to submit. Papers you need for a limited period, such as tax documents and warranties. Papers you must keep indefinitely, such as birth certificates, passports, and property deeds.
Everything else goes. Old bank statements, expired insurance policies, manuals for appliances you know how to use, greeting cards without profound meaning, lecture notes from courses you completed years ago. Shred sensitive documents. Recycle the rest.
Create a single place for incoming papers. A simple accordion file or a single drawer with hanging folders handles the papers that remain. The goal is to prevent papers from accumulating on every surface in the house.
Category Four: Komono
Komono is the Japanese word for miscellaneous items. Kondo breaks it into subcategories: kitchen items, bathroom items, cleaning supplies, electronics, office supplies, linens, tools, hobby supplies, and so on.
Tackle one komono subcategory at a time. Gather every kitchen utensil onto the counter. Gather every electronic cable into a pile. The subcategory approach prevents overwhelm.
The spark joy test applies to komono, but some items are functional rather than joyful. A can opener does not spark joy, but you need one. For purely functional items, keep them without guilt. The avocado slicer that has never sliced an avocado fails both the joy test and the function test.
Category Five: Sentimental Items
Sentimental items come last because they are the hardest. By the time you reach this category, you have practiced the KonMari method on hundreds of items. Your ability to sense joy is sharpened. You trust your own judgment more.
Sentimental items include photos, letters, gifts, childhood keepsakes, inherited items. Photos are often the largest subcategory and the most emotionally demanding.
The spark joy test applies without modification to sentimental items. If a photo brings back a happy memory, keep it. If it triggers guilt or a memory you would rather not revisit, release it. Kondo is clear: you are not obligated to keep photos that make you unhappy.
Timeline and Common Mistakes
A realistic timeline is three to six months. People who finish in a weekend are either living in a studio apartment or skipping steps. The process requires sustained attention over weeks and months.
The most common mistake is tackling the categories out of order. Starting with sentimental items guarantees emotional exhaustion and an abandoned project. Starting with clothing as prescribed builds momentum for the harder categories ahead.
Another mistake is involving family members in your decluttering decisions. Kondo is firm: declutter your own things, not your spouse’s or children’s things without their consent. Imposing your joy standards on someone else’s possessions creates resentment.
The third mistake is treating KonMari as a one-time purge rather than a lifestyle shift. The spark joy test becomes a permanent filter. You stop buying things that do not delight you because you know how it feels to be surrounded only by things that do.
The KonMari method is not about minimalism for its own sake. It is about creating a home filled with things you love. The number of things is less important than your relationship with each one.
