/ »Booklog / Yuko Abe’s Love for Picture Books (Mainichi Shimbun, June 29, 2018)
Every day, all sorts of clouds drift across the sky. What are those clouds, anyway? Who knows! Perhaps that thin, hazy veil covering the sky is a curtain drawn by a sleepy giant, trying to block out the dazzling morning light. Could that oval-shaped cloud floating all on its own be a cushion for a *tengu* (a mythical mountain spirit) to rest on? And those towering, billowing clouds—could they be the home of a family of dragons? This picture book invites children to let their imaginations soar, inspired by the shapes of the clouds above.
Though we can never reach out and touch them to see what they’re truly made of, clouds are always there whenever we look up. If children can grow closer to the clouds, their daily lives are sure to become even more delightful. To help children spot the very same clouds in the real sky that they see in these pages, the book features recognizable, classic cloud formations—such as towering cumulus clouds or lens-shaped lenticular clouds—rather than just random, fleeting shapes that happened to appear for a single moment. What kind of clouds are out in the sky today? Looking up at the sky becomes something to truly look forward to.

Pages: 192
Recommended for ages 9 and up (4th grade and above): Eight mysterious and uncanny tales.
From an old, disused music room, the faint, tinkling notes of a melody drift out. You open the door—and who—or what—could possibly be inside!?
You head to the park for early-morning soccer practice, only to find the entire area blanketed in a thick, impenetrable fog. When your soccer ball vanishes into the mist, a sudden sense of dread takes hold—and as you turn to head home, something happens...
While driving toward a hot spring through a raging blizzard, the road grows narrower and narrower, until you find yourself completely trapped, unable to move...
