Do china and japan speak the same language?

Answer 1

No, the two languages are separate. They would have to learn each others language to understand each other or perhaps both learn English because knowing English would mean that they would be understood almost everywhere.

Answer 2

No. In fact the languages are not even remotely related. The reason people think they are similar is that Japanese uses about 2000 Chinese characters in its writing system.

Chinese is a syllabic language: units of meaning are typically 1 syllable long.

Japanese has mostly multi-syllabic words.

Chinese dialects also use tone to indicate meaning. Japanese doesn't have this feature.

Answer 3

They speak different languages...there are different forms of Chinese that they speak in China, and forms of Japanese in Japan.
