Which religion could be so thin? (6)

I believe the answer is:

shinto

I'm a little stuck... Click here to teach me more about this clue!

'which religion' is the definition.
I can't tell whether this defines the answer.

'could be so thin?' is the wordplay.
'could be' indicates anagramming the letters.
'so'+'thin'='sothin'
'sothin' with letters rearranged gives 'SHINTO'.

Can you help me to learn more?

(Other definitions for shinto that I've seen before include "Religious system" , "Japanese religion revering ancestors" , "Japanese worship" , "Japenese religion revering ancestors" , "Japanese ancestor-worshipping religion" .)

I've seen this clue in the Sydney Morning Herald.
