  Gravitational waveforms generated by unequal mass black hole binaries are
expected to be common sources for future gravitational wave detectors. We
derived the waveforms emitted by such systems during the last part of the
inspiral, when the larger spin dominates over the orbital angular momentum and
the smaller spin is negligible. These Spin-Dominated Waveforms (SDW) arise as a
double expansion in the post-Newtonian parameter and another parameter
proportional to the ratio of the orbital angular momentum and the dominant
spin. The time spent by the gravitational wave as an SDW in the sensitivity
range of the KAGRA detector is presented for the first time.
