A Korean grocery store in Honolulu is shutting down just months after it opened, another sign of how hard it is to run a business in Hawaii right now.

• YouMe Mart opened near the Ala Moana Walmart in February and is already closing, with empty shelves and final sale signs greeting customers.
• A store manager confirmed the closing but didn't give an exact date or say whether it might reopen later.
• Local business watchers point to sky-high commercial rents, expensive utilities, and a tight labor market as the main pressures squeezing Hawaii businesses.
• Hawaii was just ranked the worst state in the country for business, with high costs and a low business survival rate.
• Tourism is picking up, but it's not enough to offset local residents cutting back on spending, leaving businesses with less customer money to go around.

Outlook: Expect more small Hawaii businesses to struggle or close unless rents and operating costs come down.
