On the PLUTO2 Departure from Runway 34R out of RJTT; above 700 FT MSL I started a right turn direct to TORAM intersection. Shortly thereafter; we got a terrain aural alert. We were at TOGA power; autopilot was off; and climbing on the flight director. We were in VMC; at night; with light rain in the area. I was the pilot and it looked to me that we were just about over the water of Tokyo Bay to our right side; so I continued the climbing right turn direct to TORAM intersection. The terrain alert stopped after a few seconds. There were no warning lights associated with the aural alert; and no known terrain in the area.
A330 First Officer reported receiving a possible GPWS terrain warning while climbing out over the water after departing RJTT.
