In the summer of 1993 while resting in Karuizawa, there was a surprising episode where a large-sized dog suddenly jumped just before the eyes of Princess Mako held in the arms of her mother (Princess Kiko), but she used her wit to get through the situation by saying to the surprised dog's owner 'Oh, the dog wants to be my friend.'
