Oh...um...
I cant remember anyone called Yutaka in the Bleach series, unless they were a minor filler character..
The closet i can think of to Yutaka, would be Ukitake (i used to mix up his name all the time) however if I'm mistaken then you have my apologies =]
But yes, if it was Ukitake Jushiro you were looking for then heres a little bit of information I've found on him:
Ukitake Jushiro:
The captain of the 13th Division (Rukia's division) He has a sickly looking appearance with long white hair. Despite his illness, Captain Jushiro is known to be a powerful fighter. He is one of the pioneers of Yamamoto's academy and was personally trained by Yamamoto himself. Captain Jushiro is a highly respected character for his loyalty, honesty and personal sense of justice.
In brief, he's the pale sickly captain with long white hair..
