Hundreds chose to ring in the new year by shopping. Several locations on Oahu offered "Happy Grab Bags" for Fukubukuro, a time-honored Japanese retail tradition.

The annual event gave shoppers the chance to buy bags full of mystery items, worth at least twice the amount they're sold for. That's means a bag bought for $50 could contain at least $100 in merchandise at full retail value.

The surprise? Shoppers don’t know what's in the bag until after they buy it.

“My first stop was Coach," said Ala Moana shopper Kim Billon. "I got there at 9:30 this morning. It was kind of busy, but we were able to walk in and they had a lot of merchandise available at different price points, which was great. Hopefully, I get something really good!”

Over 50 stores at the Ala Moana Center participated in Fukubukuro, from ABC stores and Godiva Chocolate, to Tory Burch and Versace. Stores like Maui Divers Jewelry say Fukubukuro is one of the best day of the year for sales.

Select stores at International Market Place, Royal Hawaiian Center, and T Galleria by DFS in Waikiki also offered Fukubukuro to shoppers this new year.
