Taimatsumaru is a fire-bearing bird yokai depicted in Toriyama Sekien’s Hyakki Tsurezure Bukuro. Shown as a raptor wreathed in flames from beak and talons, it casts uncanny light across the deep mountain night. Sekien links it in his notes to the glow of the “tengu pebbles,” interpreting it as a force that hinders ascetics in training. Its fire is not a practical torch but a delusive flame that leads night travelers astray. No specific historical locations of appearance are recorded.
