Why learn Japanese ?

Japanese is not a compulsory language in Hong Kong, so why should my child learn Japanese?  

Exposing children to a foreign language at an early age is good for their development and increases their chances of becoming proficient in the language as well as allows them to experience different cultures.  Japanese is a unique language with a large range of distinctive characters allowing the children to experience different ways of understand a new language.  Since Japanese has three different characters (Hiragana, Katakana, Kanji) it is a hard language to start when you are older as there is much more to learn compared to other languages but learning such a language at a young age will not only help the childrens understanding of different languages but also will allow them to learn the best methods to learn a new language in the future as they will benefit from this experience.
