The article discusses the problems associated with tunnel construction in Japan. The natural rock formation of the country affected by ancient tectonic action coupled with volcanic activity has resulted in mixed geological conditions of very hard rock and decomposed weak ground. As most of the country's cities are located on river deltas, tunnelling construction encounters low strength fluvial deposits and high water levels. Ground treatment such as grouting, dewatering and freezing are required to aid excavation and to protect the work face. Details are given of tunnelling construction in progress in Japan including railway, highway, underground railway and water supply tunnels. /TRRL/
