    "abstract": "The Tokai-to-Kamioka (T2K) experiment is a second generation long baseline\nneutrino oscillation experiment which aims at a sensitive search for the nu_e\nappearance. The main design features of the T2K near detectors located at 280 m\nfrom the target are presented. Scintillator counters developed for the T2K near\ndetectors are described. Readout of the counters is provided via WLS fibers\nembedded into S-shape grooves in a scintillator and viewed from both ends by\nmulti-pixel avalanche photodiodes operating in a limited Geiger mode. A\ndesription, operational principles and the results of tests of photosensors\nwith a sensitive area of 1.1 mm^2 are presented. A time resolution of 1.5 ns, a\nspatial resolution of 9.9-12.4 cm, and a MIP detection efficiency of more than\n99% were obtained for scintillator detectors in a beam test.",
