noun
the whole world; all under heaven
Literary or classical term for the entire world or all of creation; not common in everyday speech.
万天に響き渡るような大声で叫んだ。

Composed of 万 (ten thousand, myriad) and 天 (heaven, sky), literally 'myriad heavens'. The exact historical derivation is uncertain; the spelling is conventionally associated with the meaning 'the whole world'.
