Mount Juif Errant (4)

I believe the answer is:

fuji

'mount' is the definition.
(I have seen 'Mount of Japan' mean 'fuji' so perhaps 'mount' could also mean 'fuji')

'juif errant' is the wordplay.
'errant' indicates an anagram (errant can mean travelling or straying).
'juif' with letters rearranged gives 'FUJI'.

(Other definitions for fuji that I've seen before include "Highest Jap. mountain" , "Sacred Japanese mountain" , "Japanese mount" , "Sacred Japanese peak" , "Mount of Japan" .)

I've seen this clue in The Times.
