A walk-in closet is a spacious storage area that a person can walk into, and its outstanding appeal is the amount of storage it offers compared with a standard closet. With 4 tatami of space, it can hold about 400 garments, leaving enough room to use it comfortably even when shared by the family. This article explains the different layout types and the key points for using one comfortably.

How much space does a walk-in closet generally need?

A common guideline is 2 to 4 tatami.

  • 2 tatami: Stores about 150 to 200 garments, suitable for one- or two-person households
  • 3 tatami: Stores about 250 to 300 garments, ideal for shared family use
  • 4 tatami: Stores about 400 garments, with generous space and flexibility for multiple uses

What types of layouts are available?

There are four layout types for walk-in closets.

  • 1型: A single-line storage layout. Space-efficient and lower in cost, with one wall side available for customization
  • 2型: Storage space on both sides. With 4 tatami, there is enough aisle space to change clothes, and it is easy for couples to divide usage
  • L型: An L-shaped layout that secures storage capacity even in less than 2 tatami. A full-length mirror can be installed on the open wall
  • コの字型: The highest storage capacity. With 4 tatami or more, it can store clothing, bedding, and even suitcases

How should you choose the right storage type?

  • Hanging type: Recommended for people with many garments that need to be hung, such as suits and coats. Making use of the lower space is the key
  • Shelving type: Suited to people with many small items such as shoes and bags. It requires a certain amount of space
  • Modular shelving type: Commercial cabinets can be combined freely. It can also adapt flexibly to changes in family structure

What are the three points for creating a comfortable walk-in closet?

  1. Consider traffic flow: Choose a layout that does not require repeated back-and-forth movement inside the closet
  2. Match it to your lifestyle: Select the type according to the amount and kinds of clothing you own
  3. Match it to the intended use: The optimal layout differs depending on whether it is for a single person or shared by the family
