THE Hillingdon winner of an unclaimed prize to win a once-in-a-lifetime trip to Japan is being sought by the Asian-inspired brand itsu.

With 25 days left to claim, itsu is increasingly anxious to find the winner and let him or her know the good news before it’s too late.

The winner has received two emails but is yet to reply.

Louise Crighton, brand manager, said: “This is the first time in our history of running competitions that someone hasn’t claimed. We’re completely stunned.”

The trip to Japan includes a helicopter ride over Tokyo and a visit to Mount Fuji.

itsu is urging anyone who bought one of its rice’n’oodles cups at the Co-Op in Long Lane to check their inbox.
