Contents of primarily Japanese porcelain (5)

I believe the answer is:

imari

'japanese porcelain' is the definition.
(type of Japanese porcelain)

'contents of primarily' is the wordplay.
'contents of' indicates a hidden word.
'IMARI' is hidden within 'primarily'.

(Other definitions for imari that I've seen before include "Type of rich Japanese porcelain" , "Pottery" , "Richly-decorated Japanese porcelain" , "Jap. Porcelain" , "Japanese earthenware" .)

I've seen this clue in The Independent.
