Translation guide
To describe someone or something that is famous all over the world. In Japanese, this is most naturally expressed with the phrase 世界的に有名な (sekaiteki ni yūmei na) or the compound 世界的 (sekaiteki) used attributively. Direct translations like 世界有名 are not standard.
He is a world-famous singer.
This is a world-famous brand.
A shorter, more compact adjective meaning 'global' or 'world-class'. Often used in compounds or directly before a noun. It implies worldwide scale or recognition.
a world-famous company / a global corporation
worldwide fame
Literally 'known to the world'. A more descriptive alternative, often used in explanations or formal contexts.
That author is known worldwide.
A more literary or formal way to say 'world-famous', often used in written descriptions or news.

Do not use 世界有名 (sekai yūmei) or 世界的有名 (sekaiteki yūmei) without the particle に. The correct adverbial form is 世界的に有名な. Also, 世界的 (sekaiteki) alone can be used as a na-adjective, but it is less common in casual speech.
