It is pretty likely that the native grid is not rectilinear — if you check the output from ncdump you’ll see that the lat and lon coordinates vary in 2 dimensions: i and j. You will need a PDEF file to interpolate to a regular grid. My scripts for doing this are in ftp://cola.gmu.edu/pub/jma/cmip5/. Start with the README file.
