Reports of scammers across Japan taking advantage of the celebratory mood ahead of this week's Imperial succession have caused a stir on social media.

The nation is now in the middle of an unprecedented 10-day Golden Week holiday period, made longer this year after the government designated Wednesday a national holiday to put Japan in a festive mood for the Imperial changeover. After Emperor Akihito abdicates Tuesday, his son, Crown Prince Naruhito, will ascend the Chrysanthemum Throne the following day.

But the occasion has apparently become a golden opportunity for con artists trying to make a profit by selling tiny Japanese flags on the streets of major cities, according to reports from social media users who either fell victim to the scam or managed to escape it.
