日本城市内和城市之间的建筑投资仍是必不可缺的，预测将在随后的20年中仍会持续高投资率。在这种情况下，隧道挖掘技术将扮演重要角色，其中TBM技术在追求高效掘进和节支的高机械化建筑技术中将唱主角戏。日本在盾构TBM技术领域有着极大的贡献，其新发展的技术不断涌现。在日本，岩石隧道的TBM在石质隧道挖掘中正日益显示其重要的地位。
Investment in construction in and between cities in Japan is still essential, and it is predicted that there will still be high rates of investment for the next 20 years. Under such circumstances, tunnel excavation technology will play an important role, of which TBM technology will play a leading role in the highly mechanized construction technology for efficient excavation and saving. Japan has made tremendous contributions to the TBM technology in the shield, and its emerging technology continues to emerge. In Japan, the TBM of rock tunnels is increasingly demonstrating its importance in stope tunnel excavation.
