I recommend you throw out anything that does not fall into one of three categories: currently in use, needed for a limited period of time, and must be kept indefinitely.

Start with clothes, then books, documents, komono and finally keepsakes or sentimental items.

storage should reduce the effort needed to put things away, not the effort needed to get them out.

Papers are organised into only three categories: needs attention, should be saved (contractual documents), and should be saved (others).

When your room is clean and uncluttered, you have no choice but to examine your inner state.

Clutter has only two possible causes: too much effort is required to put things away or it is unclear where things belong.

Gathering every item in one place is essential to this process because it gives you an accurate grasp of how much you have.

The ability to avoid excess stock depends on the ability to simplify storage. The secret to maintaining an uncluttered room is to pursue ultimate simplicity in storage so that you can tell at a glance how much you have.

Tops (shirts, sweaters, etc.) Bottoms (trousers, skirts, etc.) Clothes that should be hung (jackets, coats, suits, etc.) Socks Underwear Handbags, etc. Extra items (scarves, belts, hats, etc.) Clothes for specific events (swimsuits, uniform, etc.) Shoes
