Kyou ha yasumi jan! 今日は休みじゃん！ Today is holiday!
I heard that "-jan" is yokohaman dialect. Other one says it's Koushu dialect. Anyway "jan" is a dialect. I use this often in Twitter. Because I'm live in Kanagawa pref.
In South Kanto region, "jan" is usual. But people from Kansai region dislike "jan". A man from Kyoto whom I met in Tohoku region says that it doesn't seem trusty. I was shocked he was angry. But he loves Kyoto dialect. I think it's no fair. I think people from Kansai have advantages in talking casually. He said that Yokohaman dialect speakers seem foolish too.
Now I think it's not big thing, but when I'm a university student, I use Japanese like NHK, and don't use Kanagawan dialect. I used to feel bad about that.
I've remembered suddenly.
