Description
Tofu-Kozō is a yōkai depicted as a child-like figure with short black hair, constantly sticking out his tongue, and typically dressed in a traditional kimono paired with a wide-brimmed straw hat, reflecting the attire of Edo-period tofu vendors. He is invariably shown carrying a tray of tofu, often including a specific variant known as *momiji-dōfu*, featuring a pressed maple leaf design.

Originating during Japan's Edo period, specifically the Anei era (1772–1781), Tofu-Kozō lacks roots in ancient folklore or pre-Edo kaidan tales. He emerged as a distinctly urban yōkai character, gaining popularity through kibyōshi picture books, toys, and advertisements. Early depictions emphasized an oversized head or occasionally a single eye, though these traits evolved toward a more conventional childlike appearance by the late Edo period. His creation is theorized to stem from commercial influences—possibly as a promotional figure for tofu shops—or as a product of Edo-era storytelling games like Hyakumonogatari Kaidankai. Despite similarities to the older yōkai Hitotsume-Kozō, researchers generally regard them as separate entities, though their legends occasionally intertwine in modern interpretations.

Across *GeGeGe no Kitarō* adaptations, Tofu-Kozō maintains a consistent personality: amicable, timid, and averse to confrontation. He frequently occupies background or supportive roles but receives focused narratives in several episodes. In the 1985 anime (episode 106, "Tofu-Kozō and Yamagami"), he appears alongside the yōkai Yama-no-Kami. The 2007 anime features him in episodic cameos and ending animations, with episode 34 ("Yōkai Yokochō's Cruise to Hell") showcasing his enhanced reflexes for dodging human attacks and stopping bullets with his tongue—though the tongue is noted as a vulnerability in earlier lore.

The 2018 anime expands his involvement. He appears fleetingly in episode 1, visible to protagonist Mana before vanishing. In episode 23 ("The Yōkai Apartment Secret Story"), he seeks housing assistance from Sunakake-Babaa. Episode 35 depicts him participating in yōkai assemblies concerning threats to their forest. His most prominent role occurs in episode 61 ("Tofu-Kozō's Mold Pandemic"), where he aids Kana, a pop idol struggling with depression, by offering emotional support—highlighting his compassionate side despite his typically passive nature.

His abilities include enhanced reflexes for evasion and bullet-catching, as well as brief vanishing acts. His signature tray of tofu serves both as a defining accessory and a narrative device. In folklore-inspired narratives, consuming his tofu risks lethal mold growth—a trait retroactively added in Shōwa-era children's stories rather than original Edo tales. This mold can spread via pollen, infecting others. Manga lore also establishes the tofu itself as his weak point; striking it can destroy him.

Legends describe Tofu-Kozō as a servant-class yōkai, often bullied by stronger entities and relegated to menial tasks. He typically appears during rainstorms near bamboo groves, offering tofu to passersby—a gesture combining benign folklore with modern horror elements. In contemporary Japan, therapists use his submissive portrayal in anti-bullying education. His enduring cultural presence is evidenced by a bronze statue on Mizuki Shigeru Road in Sakaiminato.
