Otoroshi and Yamabiko from the Bakemono no e Scroll

The top of the frame is dominated by the Otoroshi, a massive creature consisting primarily of a blue, demonic face with a wide, red, lipless mouth, protruding white fangs, and bulging eyes, all framed by an immense, cascading mane of black hair. Below and to the left, a smaller, dark-furred creature with a pink-toned torso and a broad, grinning expression—identified as a Yamabiko—stands in a dynamic, slightly hunched pose. The figures are painted in ink and light color against a plain, off-white paper background, characteristic of Japanese handscroll art.

These creatures belong to the Japanese tradition of yōkai, or supernatural monsters, which were popularized in Edo-period scroll paintings such as the 'Bakemono no e' (Scroll of Monsters). The Otoroshi is traditionally associated with guarding shrine gates, while the Yamabiko is known as an echo-producing spirit of the mountains.
