National Diet Library
In the Edo Period e-sugoroku, the "Jikkai Sugoroku" (at the National Diet Library) and the emakimono "Hyakki Yagyō Emaki" (Oda Gōchō, 1832), they are depicted by the name "akashita", but in depictions closer to the later mentioned "Akaguchi", it is depicted differently from Sekien's picture, and there is no depiction of a sluice.
