たからものはふつうの日
Children’s Book Illustration Project
A story about the quiet value of ordinary days.
ABOUT THE PROJECT
About
This picture book was created to gently remind us of something we often forget—
that ordinary days are, in fact, irreplaceable.
Inspired by a real story of a child living with illness,
the project carries a quiet message:
to live fully in the present moment,
and to recognize the beauty in what seems “normal.”
“今を生きることの尊さ”
“ふつうの日の価値”

Illustration Process
Each illustration was developed through a gentle, layered process:
from rough emotional composition,
to refined structure,
to final color that supports the atmosphere of the story.
