Wanchan (ワンチャン) is a popular piece of Japanese youth slang derived from the English phrase ‘one chance.’ While it literally translates to ‘one chance,’ it has evolved to mean ‘a possibility,’ ‘a decent chance,’ or even a way to suggest doing something on a whim. It is primarily used in casual social settings.
In modern Japanese, saying ‘wanchan’ implies that there is a non-zero, often optimistic, possibility of something happening. Whether you are discussing the likelihood of finishing a project on time or suggesting a sudden trip to a restaurant, ‘wanchan’ carries a lighthearted, slightly hopeful nuance.
Friend A: Tonight, do you want to go to the karaoke bar?
Friend B: I have a lot of work, but… wanchan maybe? Let’s see how fast I finish!
It is important to remember that this is highly colloquial. You should avoid using it in formal business settings or when speaking to superiors, as it can sound overly casual or dismissive of professional commitments.
Pro-Tip: Just like the term Ari, which signifies approval or ‘possible,’ wanchan is often used to signal that an idea or plan is within the realm of reality. If you want to express that something is very likely, you might say ‘wanchan aru’ (there’s a chance). If you are feeling uncertain but optimistic, a simple ‘wanchan!’ works as an exclamation of hope.
