100 story house

I consider myself lucky to have been able to publish this fresh number picture book that I have never seen before. It's not that there haven't been books to read as you progress upward, but there has never been a book designed to maximize the feeling of going up to the 100th floor like this book. Moreover, the house scenery that unfolds as you go up each floor may be so detailed, and the facial expressions and actions of the anthropomorphic animals may be so humorous, that children create stories by reading and looking at them over and over again.
A good picture book is one that has a hidden source of stories that creates new stories no matter how many times you look at it. The whole story has one big plot, and each 10 floors have different mice, squirrels, frogs, ladybugs, snakes, bees, and woodpeckers. Because it contains stories of bats, snails, and spiders.
I was very curious about who wrote this book and what process they went through to create such a novel imaginary picture book. Perhaps the same goes for readers of this book.
Coincidentally, the author's story about this book was posted in detail on the website of the Japanese publisher that published this book.
Since the author's voice is expressed so vividly, I decided to introduce it in summary as I thought it would be helpful in understanding and enjoying this book. About two years ago, my daughter started learning math when she was in the first grade of elementary school, and since she had trouble learning the sense of numbers, I thought it would be a good idea to borrow the structure of the book and make it into an easy-to-understand picture book. Something is drawn on each of the 2 floors, so there are 1 of them, making a total of 10. And when I thought about whether it would be better to stack things up one by one to form a large number rather than simply lining them up, I got crazy about using a 10-story building. So, first, I drew a picture of a simple house about 100 stories high. Then my daughter said, “Dad, tell me a story with this!” And I am very happy about it.
While talking and playing with my daughter, I came to the idea that it would be a good idea to read the book upwards to represent the setting and height of the main character ascending to the 100th floor. I thought that if it went well, it would be a new type of book that I had never seen before.
It was good up to that point, but when it came to the actual work, creating a detailed story and creating a variety of rooms on the 100th floor was not an easy task, so it took a lot of time. Halfway through, I thought that I could just think of the place I wanted to go and the room I wanted to live in. From then on, the process was easy and I was able to draw with pleasure.
This book is 1, 2, 3, 4… We hope that it will go beyond a simple picture book that only teaches numbers and become a new type of number picture book in which children will naturally learn the concept of numbers while enjoying colorful pictures and stories. Now, let's become Dochi, the main character, and climb to the top of the 100th floor, pounding her heart, to see which room and which animal she will encounter next? -I hope Toshio Iwai and the whole family will enjoy this book for a long time until it becomes popular.
