The wiki claims he was the captain of squad 10 and links to the chapter in the manga that this occurred: http://bleach.wikia.com/wiki/Isshin_Kurosaki

@MadaraUchiha it doesn't really seem like a plot hole, I mean there are too many hints about ichigo's father that one might assume there should be a big story (maybe even as big as an arc) behind him.

So what is Ichigo's father and why does he know what he knows? Also, why he doesn't seem to have any Shinigami powers, while he knows so much about them?

Isshin Kurosaki used to be a Shinigami of an unknown division and rank. According to bleach.wikia.com:

> About twenty years ago, he ceased being a Shinigami, losing most of his powers.

He still has a shikai, which he uses during the Fake Karakura arc.

Spoiler:
