Reminder to look up when taking drink in Japan (8)
I believe the answer is:
keepsake
'reminder' is the definition.
(I've seen this before)
'look up when taking drink in japan' is the wordplay.
I cannot really see how this works, but
'drink' could be 'sake' (sake is a kind of drink) and 'sake' is located in the answer.
'look up' could be 'keep' (I've seen this in other clues) and 'keep' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for keepsake that I've seen before include "Thing retained in memory of giver" , "Gift, reminder" , "to remember one by" , "Souvenir, memento" , "It serves to keep a person in mind" .)
