TREASURE (Korean: 트레저; Japanese: トレジャー) is a 10-member boy group under YG Entertainment. The group was formed through the reality show YG TREASURE BOX which aired from November 2018 - January 2019. They made their long-awaited debut on August 7, 2020, with the single album "The First Step: Chapter One".
At the conclusion of YG Treasure Box, Treasure was first announced as a 7-member group consisting of Bang Yedam, Haruto, So Junghwan, Kim Junkyu, Park Jeong Woo, Yoon Jae Hyuk, and Choi Hyunsuk. Afterward, Yang Hyunsuk announced that they will also be debuting a second boy group which will be called Magnum which included Ha Yoon Bin, Mashiho, Kim Doyoung, Yoshinori, Park Jihoon, and Asahi.
The group was supposed to debut as TREASURE 13 and then promote separately as units Treasure and Magnum. However, after the agency's scandals that ultimately lead to the resignation of Yang Hyunsuk, the group's debut plans were delayed and changed. The re-organization of the group's debut plans also included the cancellation of Ha Yoon Bin's contract due to personal reasons—leaving the group with 12 members.
Eventually, it was announced that the group will become a permanent 12-member group and will be called TREASURE.
Treasure debuted on August 7, 2020, with the single album, The First Step: Chapter One, the first installment of The First Step series.
On November 8, 2022, YG Entertainment announced that Mashiho and Yedam had terminated their contract and left the group.
On June 11, 2023, YG Entertainment announced Treasure's sub-unit T5 including the following members: Jihoon, Junkyu, Jaehyuk, Doyoung, and Junghwan.
