Several shopping centers on Oahu will be offering "Happy Grab Bags" for Fukubukuro, a time-honored Japanese retail tradition.

On New Year's Day, Jan. 1, 2018, merchants sell these lucky bags for at least half of what they are actually worth. The catch? The contents of the bags are a complete surprise not to be revealed until they are purchased.

All sales are final.

Ala Moana Center

Ala Moana Center will be open on Monday, Jan. 1, from 9:30 a.m.-9 p.m. Shoppers should plan to arrive early, as most of the bags sell out shortly after stores open.
