Has suit tailored, getting the Japanese treatment (7)
I believe the answer is:
shiatsu
'the japanese treatment' is the definition.
(I've seen this before)
'has suit tailored' is the wordplay.
'tailored' indicates an anagram (the letters are customised ).
'has'+'suit'='hassuit'
'hassuit' anagrammed gives 'SHIATSU'.
'getting' acts as a link.
(Other definitions for shiatsu that I've seen before include "Form of treatment that entails pressure with the fingers on specific points on the body" , "Japanese healing therapy using massage with the fingers" , "Massage therapy using pressure points" , "Japanese healing massage technique" , "form of massage" .)
