Honolulu fire investigators determined the cause of a kitchen fire at Makai Market Food Court at Ala Moana Center early today was accidental.

A stove at Aja Sushi & Bento was “inadvertently left on and ignited accumulated grease” just before 3 a.m., said Honolulu Fire Spokesman David Jenkins.

Personnel at Ala Moana Center called 911 after they observed smoke emerging from the food court. Firefighters arrived and observed a small fire in the kitchen at Aja Sushi.

The blaze was extinguished by 3:07 a.m. Damage to the kitchen was estimated at $45,000. Jenkins said the eatery’s fire extinguishing system located above the stove contained the fire and prevented about $1.2 million in damage to Aja Sushi.

No one was inside the eatery at the time of the fire and no injuries were reported.

Other eateries at the food court were unaffected by the fire.
