ITER Test Blanket Module (TBM) program is the first module scale breeding blanket performance test in the real DT fusion reaction environment which will be realized in ITER. Therefore, it is regarded as one of the most important development step of breeding blanket for DEMO. For the TBM program, Japan has the plan to test Water Cooled Ceramic Breeder (WCCB) TBM as the primary candidate breeding blanket. Keeping consistency with ITER construction activities, TBM design and development activities are being performed. This paper overviews the recent achievements of the development of the module fabrication technology and tritium production technology of the WCCB TBM in Japan.
