Shiiya Riverしいやがわ

Among the many kappa legends nationwide, the hyousunbo stands out as a water apparition of Hyuga renowned as "the kappa that keeps promises." Although a dangerous being that drags children playing in the river to their deaths, it made a pact with the villagers—"I will not take their lives until a certain rock rots away"—and faithfully touched the rock countless times to check on it, thereby polishing it smooth. The detail of this "Hyosubo Rock" transcends a simple ghost story, conveying the memory of a negotiation between humans and a water god. The belief in its seasonal migration—living in the river during spring and autumn and the mountains in winter—reflects the southern Kyushu folk view of kappa as avatars of water and mountain gods. The dedicatory sumo matches held annually at the Suijin-buchi of the Tsuboya River are remnants of local rituals to pacify a raging water god through wrestling. Connected to the garappa and kawantaro of southern Kyushu's kappa culture, the hyousunbo remains a unique entity with a name and legend native to Hyuga, telling the story of the boundary between water and humans.
