I present the latest results on the black hole X-ray binaries observed by Monitor of All-sky X-ray Image (MAXI) and their near optical/near-infrared counterparts.  MAXI J1535-571 is a black hole binary candidate discovered by MAXI and Swift at the outburst in September 2017.
We performed a series of near infrared observations with IRSF in J, H, and K bands, in which we found significant flux variations on short time scales.  We find that there are at least two emission components with different spectral and timing properties: one with steep spectrum and rapid variability, which is probably attributed to the synchrotron emission from the jet, and another with blue color and less time variable, probably associated with the accretion disk irradiated by X-rays.  A similar spectral decomposition was also found in another black hole binary GS 2023+338/V404 Cyg in its outburst in 2015.
