One day I was asked by my child,“What do you mean by mottainai?”How can I explain this word?There are some Japanese words that cannot be translated into English and mottainai is one of them.It is difficult to explain even in Japanese.This is why I started to think about making this picture book.――Mariko Shinju ``What kind of meaning is mottainai?'' my son asked me one day.

I wanted to convey this message somehow, so I started writing this picture book. -- Pearl Mariko Comparez les prix de: Kadokawa in Merchandising
