Development of position-sensitive scintillator detectors at the J-PARC/MLF is briefly reviewed. The detector development for the neutron scattering instruments in the J-PARC/MLF initiated back in 2001. After the basic experiments and design study we have produced first beam line detectors in 2008 both with the one and two-dimensional position-sensitivity. With an extension of the fiber detector technology the detector that has an active area of 256 256 mm with a 4-mm spatial resolution was designed and made for the single crystal diffractometer, SENJU, in 2011. In the presentation recent development work including the alternative detectors to He gas is also introduced as well as the new detector development for the nextiBIX instrument.
