Toy from Tokyo -- youngster's (2-2)

I believe the answer is:

yo-yo

'toy' is the definition.
(I know that yo-yo is a type of toy)

'from tokyo youngster's' is the wordplay.
'from' says the answer is hidden in the clue.
'YO-YO' can be found hidden inside 'tokyo youngsters'.

(Other definitions for yo-yo that I've seen before include "Toy (with ups-and-downs!)" , "Move up and down" , "Fluctuate rapidly" , "-- - -- Ma, American cellist of Chinese/French origins" , "Fluctuate repeatedly" .)

I've seen this clue in The Telegraph.
