“Haru and Koharu and the Rainbow Bridge" is a children's educational book.

Haru and Koharu, who are twins, go on an adventure to look for the end of a rainbow.

Haru and Koharu, the twins, found a map that their father drew when he was little, and they started going treasure hunting with the map. What kind of treasures would they find?

Haru and Koharu experienced many adventures in the mountain where their father hide his treasure. One day they saw raccoon’s family and one day they had quiz battle with the wind boy Kitakaze-Kozo and one day they were chased by a huge tadpole.

The stories split into many scenes and children can choose which adventures they want to go on. The illustrations are drawn with color pencils to give the effect of warm handwriting and using a minimum of digital effect children can get into the story deeper. Please enjoy this new style of digital story that is different from traditional paper books.


When you finish reading a story, please enjoy the“Fun”section.
・Their mother introduces a cooking recipe referring to the story.
・Enjoy your children’s favorite maze. 3D maze is also available and enjoy the feeling of being inside the maze.

The "Fun section" was made for your family to enjoy some conversations togather.
I hope I can help exciting children's curiosity.

Are you ready to go treasure hunting with Haru and Koharu now?

Let’s go!
