HAHAHA you made me laugh, if only it was even possible to say ching chong in Japanese, considering they don't have a "g". You may need to be directed to a Chinese post.
What are you talking about? The Japanese language has a "g". One of the most commonly known words, for example: ありがとう (arigatou), which means "thank you". There's a "g" in it. There is no "g" by itself, no, but they certainly do use a "g" in their language.
