Keiko- young mother
"Guri and Gura" series books.
by writer Rieko Nakagawa and illustrator Yuriko Yamawaki
Two adorable field mice who fall into wonderful adventures and meet fascinating new friends.
Why?
My mother used to read the books when I was young, and it was exciting.
Bonus:
In Japan, a comedian named Nishino published a picture book, and put the book on the web for free.
Here's the link to the English version.
