This book is the latest work by popular character artist Chiharu Sakazaki, known for JR East’s Suica Penguin, Chiba Prefecture’s Chiba‑kun, and many more.

It introduces 111 actions of a “penguin who is good at self‑care.” You can read it from the beginning or open to any page you like. The actions range from simple everyday joys—taking a long bath, browsing a drugstore, eating a parfait, buying a new bag, going out without your phone—to supportive ideas for low‑energy days, such as stepping away from the group, practicing saying “no,” or choosing to walk away.

The book includes 130 penguin illustrations, featuring penguins eating sour food, laughing, warming their eyes, taking walks, doing yoga, relaxing in a sauna, and more. It can be enjoyed as an art book as well.

Many readers say that reading it before bed helps them sleep better. The gentle drawings and short accompanying messages offer comfort, hints for handling worries, and small sparks of hope. Simply reading becomes an act of self‑care.

The editor notes that the concept began with the illustrations themselves—penguins full of humor, cuteness, honesty, calmness, and quiet kindness. The theme of “self‑care” naturally emerged from their expressions. Whether the penguins are doing radio exercises, eating cake, drinking tea, or traveling, you can try imitating their actions—or simply enjoy the soothing experience of looking at them.
