Kameosa - 瓶長 - [Yokai | Tsukumogami]
• About this Yokai: Another example of a Tsukumogami - This antique water flask has become a bottomless bottle of plenty, and will magically produce an ample bounty of whatever liquid is poured inside of it: it produces an endless amount of the liquid continuously; it likes humans and LOVES to share! Just be careful, it tends to get VERY EXCITED and overflow!!! (it's very partial to sake & alcohol!!)
•Early Appearances & History:
Kameosa's Earliest named appearance was in 1781 as part of Toriyamas [百器徒然袋] Gazu Hyakki Tsurezure Bukuro it was the last one included in the book and named after one of his students who called himself a Shōjō, because he loved to drink! - The bottomless flask itself seems to be a nod in reference to a famous story/noh play:
"Shōjō Midare" - 猩々乱 - is a story about a wine seller from china who dreams of selling alcohol and becoming rich enough to support his parents: he does so, and he succeeds in selling lots! - But one day, he meets an interesting customer who's never satisfied and drinks like a fish! He will not get drunk, no matter how much he drinks!! Curious, the seller asks the strange customer his name: the customer happily responds that his name is shōjō and that he lives in the ocean! The mystery man then leaves (without paying.) – Feeling suspicious (& ripped off), the seller goes to a nearby beach with liquor in hand and he ready's a trap for this so called shojo: a big ol' crock pot full of sake. But, when he gets there. the Shojo is already red in the face flat-out-drunk, noticing the crock pot, it drinks some more, does an amusing, clumsy dance. When hes done. It notices that the seller has come to visit. Absolutely jubilant over the fact that the seller came out to see him (and grateful for more wine/sake) He rewards the seller with a crock pot which will never ever run out of drink! - The two then share a toast, rejoice and dance one more dance before they both pass out. - However, the man awakes the next morning, it seems that was all a dream.. he laments about his friend: but he is pleasantly surprised to realize that the magical pot is right next to him when he gets up!!
