Nissan Construction Co., affiliated with collapsed retailer Mycal Corp., has filed for protection from creditors.
The firm said Sunday it filed for protection the previous night with the Tokyo District Court under the Corporate Rehabilitation Law.
The Tokyo-based midsize general contractor has had considerable difficulty in collecting some 12 billion yen from the Mycal group for work it has completed. The retailer, which owned nearly half of Nissan Construction, went under in September.
