The ultimate luxury is a comfortable time spent at home.
It's okay if you don't have sense, money, or space!
Simple rules from a popular interior designer
Transform your precious home into a stylish space.

Success is guaranteed if you just follow along with what you have now!

How do you like the house you live in now? I want it to be as neat and stylish as the homes you see on TV, in magazines, and on Instagram.
But what if you have no money, no sense, and limited space? And what if it's not even your own home, but a rental or a monthly rental? Even if you're not satisfied, you can't do anything about it right away, so "stylish home decorating" tends to be put off until the distant future.
‘Interior design’ seems like it requires a lot of money and feels difficult and daunting.

But isn't "a comfortable time at home" the ultimate luxury we deserve right now? "20 Interior Design Rules," a book by a veteran interior designer that has become wildly popular in Japan, will help you solve your problems.
It contains interior design secrets that you can follow even if you don't have money or sense.
You can transform your home with just what you have, without buying more!

Interior design tips, step by step, for each location

Chapter 3 explains the interior design rules one by one for each location, including the living room, kitchen, children's room, entrance, bathroom, and washroom.
It's almost like an interior designer giving you a "one-point lesson." When we think of stylish interiors, we often think of expensive sofas and dining tables, fancy appliances, imported wallpaper, and tiles.
But there is an item that is much more important than that.
Curtains and lighting! They determine the mood of a space.
Since curtains cover a large area, if they are not the right size and are not neat, the space will look tacky no matter what you do.
Curtains that fit the window size, points to keep in mind.

Lighting is also important. No matter how well you decorate, if the lighting is not good, the interior effect will be reduced.
In addition to the main lighting, adding partial lighting creates a three-dimensional effect throughout the space, making it look wider and more cozy.
It makes you realize the importance of curtains and lighting that you may not have thought much about, such as what color bulb to choose for each space and how different the appearance of multiple lights in one space can be.

The secret to buying interior items that won't fail

"20 Interior Design Rules" also teaches you the "secrets to making purchases without fail" if you ever need to buy something.
First and foremost, when shopping online, it's important to check the size! Check the item's size, cut some masking tape, and stick it on the intended location.
We also included selection points for each item, including sofas, dining tables, dining chairs, TV stands, sofa tables, beds, bookcases, curtains, rugs, lighting, and wall clocks.
You can see that rather than just choosing based on price and design, the 'size' and 'height' that are comfortable to use are much more important.
Although it doesn't have a single photo, this interior design book offers tips applicable to any home! Recommended for anyone looking to update their home for spring.
