[citation needed] The "H" in "H Mart" stands for the store's original name, Han Ah Reum (한아름), which means "an armful" in Korean.

After cultural conflicts between Hispanic and Korean American employees in one store, the H Mart headquarters provided an intercultural training program, with translations into Spanish.

[15][16][17] As of 2021, there were 84 H Mart stores in the United States, located in New York, New Jersey, Arizona, California, Colorado, Georgia, Hawaii, Illinois, Maryland, Massachusetts, Michigan, North Carolina, Oregon, Pennsylvania, Texas, Virginia, and Washington.

In 2013, the company opened its first urban convenience format on Yonge Street and Churchill Avenue in the Toronto-suburb of Willowdale called "M2M–morning to midnight".

As of June 21, 2024 Hmart made their entry into the French Canadian province of Quebec by acquiring 3 Jang Teu grocery stores in Montreal.

In late 2007, tribunal member Lindsay Lyster dismissed their complaint on the grounds that it had no reasonable prospect of success and did not merit a hearing.

Protest organizer Jim MacDonald said the store, and other H Marts nearby, disproportionately hired Asian people, specifically Korean-Americans.

[30][31] H Mart responded in a statement that the company "does not screen employees by race, but by their capabilities"; for example, the Flushing store hires many Korean speakers to better serve its many customers who do not speak English.
