The Circumstance is probably due to Kazuya being worried about his first mission to the human world as a Captain, and in order to ensure he's up to the task he asked Fumio to indulge him in a private sparring match. Swordsmanship and Hakuda are likely off-limits to both of them, although Zanpakuto would obviously be left open to use for their powers.

The place? I always reckoned that the Kidou Corps had a private arena of sorts where members might engage in either stimulated encounters through illusions, or sparring matches against other members. Who knows, the Joyato (one of the four primary divisions to be detailed in my update to the Kido Corps page later) might even hold Tournaments there to find especially combat-ready candidates. Their match might even attract an audience, which such matches often do.
