Suiko-sama is a water deity worshipped in the Tsugaru region of Aomori as a guardian against drowning; the formal name is "Suiko Daimyōjin"[1]. Counted among the retinue of the Dragon Palace (Ryūgū), it is described both as a higher being that commands the local kappa — here called *medochi* — and, in other tellings, as a kappa itself. Its sacred images are enshrined in small wayside shrines and halls, sometimes in the form of a kappa and sometimes borrowing the form of Benzaiten. In early summer by the old lunar calendar, people offered the first cucumbers of the year and set them adrift on the river, praying that their children would not lose their lives to the water. It shares only its written name with the Chinese "suiko" of the materia medica; in truth it is a water-deity faith that grew up on its own in Tsugaru.
Folklore & Legends
In Tsugaru it has long been told that a single Suiko-sama commands as many as forty-eight kappa (*medochi*) and quells the misfortunes of the waterside[1]. For this reason people raised small shrines along the rivers and enshrined the sacred images. From the fifth to the sixth lunar month, when children begin to play in the rivers, they offered the first cucumbers of the year and floated them downstream, while each household received a protective talisman and was warned against carelessness near the water.
The sacred images take the form not only of a kappa but also of Benzaiten because both were revered as deities of water and so came to be overlaid on one another. There is also a tradition that in the early Meiji period a temple in western Tsugaru joined with local prayer rites, raising the nature of the kappa to that of a deity in order to calm a river plagued by constant drownings. Origins and shrine names differ from district to district and much remains unclear, yet the wish to "fear the water and protect the children" runs through every corner of Tsugaru.

This version digs into Suiko-sama as a faith that "raised a yokai all the way to a god." The kappa is by nature a fearsome creature that drags people into the water. The wisdom of the Tsugaru Suiko-sama cult lies in this: rather than slaying the kappa, it made the creature into a god who commands forty-eight of them as their head, entrusting it with the order of the waterside[1].
The faith was bound tightly to the lives of children. The custom of offering cucumbers and floating them downstream in the river-playing season was at once a prayer to the deity and a way of impressing on children the everyday warning, "never let your guard down at the water." Benzaiten's form is borrowed for the sacred image because two water deities naturally merged into one. It shares only its kanji name with the ferocious "suiko" of the Chinese books; in substance the two are nothing alike. Suiko-sama is a water god in the manner of the snow country — one in which people reshaped the local dread of the kappa into an object of prayer. The specific rites and incantations vary greatly from district to district, and many have not survived to the present.
