Office Seike BOOKS Co., Ltd. will release makeup artist Rie Shiihira's book "When You Understand the Why, Your Makeup Changes. Your Life Changes, Too: How to Find Your Own Makeup, Based on Bone Structure" on Amazon Kindle on August 26, 2026.
The book has drawn attention by becoming an Amazon bestseller during the pre-order period, before its release.
Amazon Bestseller on the First Day of Pre-Orders
On the first day that pre-orders opened on Amazon, the book became an Amazon bestseller.
Becoming a bestseller at the pre-order stage, before readers have the book in hand, shows how high expectations for it are.
A New Perspective on Makeup: Knowing "Why It Suits You"
The book's title is "When You Understand the Why, Your Makeup Changes. Your Life Changes, Too."
Rather than makeup techniques themselves, it focuses on knowing "why this suits me."
According to Office Seike BOOKS Co., Ltd., with a wide variety of makeup methods introduced on social media and in videos, it is not uncommon to wonder, "Why does it look good on her but not feel right on me?"
The book addresses exactly this "why." Rather than applying trends or someone else's right answer to yourself as they are, it proposes getting to know your own face and understanding why something suits you.
The idea that "there is a reason why something suits you," which Ms. Shiihira arrived at after 29 years of makeup experience and working with the faces of about 40,000 people, lies at the heart of the book.
The Message That Makeup Can Change Your Life, Too
The phrase "Your life changes, too" in the book's title suggests that makeup affects not only the face but also what is inside.
What Ms. Shiihira aims for is not only to resemble someone else's face or to hide complexes. It is to get to know your own face and your own unique features, and to change how you see yourself, including the parts you used to think of as flaws.
When the way you look at yourself in the mirror changes, your confidence changes. When your confidence changes, your expression changes, and even the people you meet and the actions you take change, according to the book.
Becoming an Amazon bestseller on the first day of pre-orders marks a new start for delivering the message of this book to many more people.
Comment from the Author, Rie Shiihira
The author, Rie Shiihira, commented that she is "truly happy" about the response from the first day of pre-orders.
She also said that she wants to tell people who, like her past self, lack confidence and struggle in a small world that they can gain confidence by coming to like themselves, and that their lives will change, through makeup, "a process of tuning the heart from the outside."
