J-PARC is a research complex of proton accelerators and experimental facilities in Japan, and also an international multipurpose user facility with the unique feature of the use of various secondary quantum beams, like neutron, muon, kaon, neutrino, etc. that are produced from the world leading 1 MW class proton beam. The materials and life science facility (MLF) is a facility in J-PARC, that produces pulsed neutrons and use them for various kinds of materials and life sciences. A high intensity and high resolution neutron diffractometer TAKUMI dedicated for engineering sciences including the strength of materials has been built and operated at the MLF of J-PARC. The present status of TAKUMI will be introduced; (1) instrument specifications, (2) covering applications, (3) unique sample environmental devices and available experiments, (4) research examples, and (5) new challenges and upgrading plans.
