Imperial Palace guards continued efforts Friday to shoo away a "tanuki" raccoon dog that has been hiding in a gap in a stone wall at the palace moat.

The 30-cm-long raccoon dog was spotted near the moat by a passerby Thursday morning. When a police officer went to the site, the animal escaped to the stone wall.

The Environment Ministry, which oversees the environment around the palace, tried and failed Thursday to catch the wayward critter. Tanuki in folklore are fond of making mischief.
