John 3:16 in Chinese / Japanese...

神は實にそのひとり子をお與えになったほどに世を愛されたそれは御子を信じる者がひとりとして滅びることなく永遠のいのちを持つためである is the full translation of John 3:16 into Japanese.

This translation comes from the Shinkaiyaku Bible (a preferred translation by many Japanese Christians).

Just for reference, from the KJV, this reads, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish but have everlasting life".

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

神愛世人甚至將他的獨生子賜給他們叫一切信他的不至滅亡反得永生 is the full translation of John 3:16 into Chinese.

This is from the Chinese Union Bible which comes from a revised version of the King James. This Chinese Bible was originally translated and printed in 1919 (several revisions since then).

Because of the origin being the KJV, I'll say that in English, this would be, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish but have everlasting life".

As with any translation, there are interesting cultural and linguistic issues. For instance, the word used for "world" in Chinese can also mean "common people". So you could say that it means "For God so loved the common people..".
This does not take away from the text, as it will be understood with the same meaning and connotation.

There is no direct Greek to Chinese translation in print (that I know of), so this is the best available. Of course, you can ask any Greek person of faith, and they will claim that a bit is lost from the original Greek of the New Testament to any of the English versions of the Bible in print.

神愛世人甚至將他的獨生子賜給他們 is the first half of John 3:16 in Chinese.

It reads roughly, "For God so loved the world, that he gave his only begotten Son".

This came directly from the Chinese Union Bible first printed in 1919.
