A moving picture decoding device 100 including: a direct mode availability judging unit 109 that, when a decoding target block should be decoded in a temporal direct mode, judges whether or not a reference picture for a decoded picture, which is in a vicinity of the decoding target block in terms of display time, is usable as a forward reference picture for the decoding target block; and a substitute process performing unit 110 that decodes the decoding target block in the temporal direct mode using a picture other than the reference picture, or decodes the decoding target block in other encoding mode.
