　More than half century has passed since first setting of swans free at the moats of National Gardens in 1953. At present, 16 swans are to be seen among the moats from the Sakurada-bori moat to the Ote-bori moat, and are fed with their bait once a day. In May, 2007, the birth of a new swan is confirmed at the Ote-bori moat, so 17 swans in all today.
