The grand opening of the new giant San-Ei supermarket at Tsukazan in Haebaru Town caused an excessive traffic jam in all southern parts of Naha City, especially in Naha’s Kokuba district. Buses were running as much as an hour later than their schedule and some routes had to be canceled altogether. Officials say that the main reason for the jam is the narrow roads in the area, and they fear that the situation will be worse on weekends.
