Organized around depictions found in kibyoshi and picture-books from the Tenmei to Kansei eras. In Yohkai Chakutōchō it is placed as a grandson of the Mikoshi-nyūdō, with lines stating it bullied a tofu seller to obtain tofu, and its image features an oversized head on a childlike body. A similarly big-headed boy appears in Bakemono Yofuke Omi-se under a different name, and scholars note its word-proximity to the sideshow and street performance “Choroken.” In modern times it is often confused with the Tofu-kozo, but folklorists advise against conflation and favor respecting each source’s naming and design differences. Shigeru Mizuki emphasized its beast-like bare feet and huge head and presented it as distinct from the Tofu-kozo.
