The T2K experiment is a long-baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton sector mixing angle { \theta}_{ 13} by observing { \nu}_e appearance in a { \nu}_{ \mu} beam. It also aims to make a precision measurement of the known oscillation parameters, { \Delta}m^{ 2}_{ 23} and sin^{ 2} 2{ \theta}_{ 23}, via { \nu}_{ \mu} disappearance studies. Other goals of the experiment include various neutrino cross section measurements and sterile neutrino searches. The experiment uses an intense proton beam generated by the J-PARC accelerator in Tokai, Japan, and is composed of a neutrino beamline, a near detector complex (ND280), and a far detector (Super-Kamiokande) located 295 km away from J-PARC. This paper provides a comprehensive review of the instrumentation aspect of the T2K experiment and a summary of the vital information for each subsystem.
