  We discuss synergies in the combination of the first-generation JHF to
Super-Kamiokande and NuMI off-axis superbeam experiments. With synergies we
mean effects which go beyond simply adding the statistics of the two
experiments. As a first important result, we do not observe interesting synergy
effects in the combination of the two experiments as they are planned right
now. However, we find that with minor modifications, such as a different NuMI
baseline or a partial antineutrino running, one could do much richer physics
with both experiments combined. Specifically, we demonstrate that one could,
depending on the value of the solar mass squared difference, either measure the
sign of the atmospheric mass squared difference or CP violation already with
the initial stage experiments. Our main results are presented in a way that can
be easily interpreted in terms of the forthcoming KamLAND result.
