In Japan, there is a widely known belief that keeping a piece of shed snakeskin in your wallet can bring good luck with money. Even people who have never done it themselves often know that snakeskin is supposed to bring good luck with money. It is not just an old saying known by older generations; younger people are familiar with it too.
One easy way to understand the idea is through the way snakes shed their skin. A snake leaves its old skin behind and appears renewed again and again. That can suggest rebirth, growth, and continued prosperity, which makes the connection with the hope that money will also “grow” fairly easy to understand.
White snakes are especially strongly associated with this kind of luck. They are often seen as particularly auspicious, and wallets featuring snake patterns or white-snake designs are sometimes sold with claims of bringing good fortune or better luck with money. The connection between snakes and wallets is not especially unusual in Japan.
That does not mean everyone knows the background in detail. Many people could not explain exactly why snakes became associated with money, even though they know the basic idea that snakes, and white snakes in particular, are considered lucky for finances. Often, the association itself survives more strongly than the explanation behind it.
If someone actually kept a real piece of shed snakeskin in their wallet, most people would not necessarily think they were extremely superstitious. It would be more likely to be seen as a small good-luck habit. A real piece of snakeskin might still get a reaction like, “You actually found one?” simply because finding real shed snakeskin is a little unusual.
Snakeskin is not kept in wallets because it has any proven power. The repeated shedding of a snake’s skin, the lucky image of white snakes, and the long-standing connection between snakes and money have all blended together. For many people, it survives as a small wish: maybe carrying it will bring a little extra luck.
