A writer loved by children around the world,
Shinsuke Yoshitake's exciting fantasy picture book!

Shinsuke Yoshitake, who became a bestseller as soon as his first picture book was published in 2013 and gained explosive popularity in Japan, Korea, China, and other countries, won the Japan Moe Picture Book Award three times in 2013, 2015, and 2017. In 2017, he won the Bologna Ragazzi Award for "I Shouldn't Have Taken Off My Clothes," solidifying his position as a world-class picture book author beyond Asia.
It is no exaggeration to say that Shinsuke Yoshitake, who is currently the most beloved author among readers around the world, has released a new and lively fantasy picture book, “The Secret of My Sleeping Habits.”
When I wake up in the morning, my hair is messy and there are drool marks on the sides of my mouth.
My pajamas are already pulled up above my belly button and the blanket is crumpled as if someone had deliberately crumpled it.
This is what most children look like when they wake up in the morning.
It's so different from when I went to bed.
In "The Secret of My Sleeping Habits," Shinsuke Yoshitake analyzes the structure of children's sleeping habits and, with added imagination, leads them into a new world of fantasy.


I planned and designed my sleeping habits
Could it be that there is a sleep habit manipulation group?

Could something have happened while we were sleeping? Could it be that "those people" were deliberately instituting various sleeping habits, like exposing my stomach or making me drool? Could it be that those people, perhaps, are part of a sleep-habit manipulation group?
Even when the children went to bed, they were clearly washed clean, put on their pajamas properly, and went to bed tidily.
But when you wake up in the morning, your hair is disheveled, your clothes and blankets are a mess, and there are even marks on your face from drool or pillow pressure.
There's no way I could have done this while sleeping! This must have been the work of someone else! This is the direction of author Yoshitake Shinsuke's imagination.
《The Secret of My Sleeping Habits》 begins with the curiosity about how our sleeping habits came to be and the exploration of their structure.
The author added some fun imagination to it.
Readers of this book may also want to add their own unique ideas.


While I was sleeping,
Into that space of imagination!

Their mission begins only after the child falls asleep.
Who are they? What are their goals? The sheer number of personnel, the scale of the equipment, the advanced technology—their dedication to the task is truly remarkable.
All actions are aimed at preventing the child from waking up.
As we follow their behavior, we begin to wonder if there really is such a structure to how sleeping habits develop.
This picture book is interesting not only for its flow and ideas, but above all, the detailed movements and facial expressions of the characters are exquisite.
Although the body structure is simple and the face is only a circle, the confusion of dropping a child and the worry when the child tries to wake up are clearly conveyed.
Rather, the looseness of the illustrations, which seem to have omitted many things, is the charm of this picture book.
Unlike Shinsuke Yoshitake's other books, this picture book has no text, so much so that it can be called a wordless picture book.
However, the various onomatopoeia, mimetic words, and pictures alone provide enough fun.
Additionally, it allows readers to fill in the blank spaces in the text with their imagination, allowing them to truly experience the joy of reading picture books.
