Ogat was a Klingon planet. It as home to a residential training academy for young Klingons studying the way of the warrior. The academy course was difficult, but the teachers were excellent.

In 2370, K'mtar suggested that Alexander Rozhenko should leave his father and attend the academy on Ogat in order to better train for a warrior's life. Worf ultimately refused, and Alexander remained on the USS Enterprise-D a while longer. (TNG: "Firstborn")
