In this article, recent topics in the high-pressure synthesis and physical properties under high pressure circumstance on Topological Kondo Insulators SmB6 and YbB12 were reviewed. As for high pressure synthesis of substitution by Ca for YbB12, high-pressure equipment using the Walker module is introduced. This equipment is used for material development of novel RB12. Furthermore some physical properties of SmB6 and YbB12 under high pressure condition are also introduced.
