  We define the log motivic nearby cycles functor. We show that this sends the
motive of a proper smooth scheme over the fraction field of a DVR to the motive
of the boundary of a log smooth model assuming absolute purity, which is
unconditional in the equal characteristic case. In characteristic $0$, we show
that the $\infty$-categories of motives over the standard log point and rigid
analytic motives are equivalent, and we relate log motivic nearby cycles
functor with Ayoub's motivic nearby cycles functor.
