In Japan, the technologies handling a large amount of tritium have been developed at TPL (Tritium Process Laboratory) of JAEA (Japan Atomic Energy Agency) and Hydrogen Isotope Research Center of Toyama University for 30 years. These facilities have been operated with no tritium release and no accident. The tritium handling technologies have thus been demonstrated by using a large amount of tritium. Through these products, the tritium handling technologies have been established in Japan also. To construct these facilities, many tritium researchers made their efforts. Significant R&D results and the above efforts are reported from viewpoint of succeed to the tritium handling technologies and of maintenance of the facilities.
