In this chapter we present an overview of the geology of the Japanese archipelago and the surrounding ocean basins. To set the scene we begin by examining the main geological features of the present-day Japanese arc system. We then move back in time to the oldest rocks known in Japan and show how these origins have developed into the modern island arc. The early geological history of Japan is represented by Palaeozoic rocks, which were derived from both continental and oceanic domains. It is unclear if this early continental margin was passive or the site of plate convergence. After the Jurassic the geological record preserves abundant evidence for oceanic plate subduction beneath Japan. This convergence has continued until the present with numerous plates interacting with and leaving their mark on the geology of Japan. At c. 25 Ma the Japan Sea began to open causing the separation of Japan from the East Asia margin to form the present island arc.

The Geology of Japan
It has been 25 years since publication of the most recent English language summary of the geology of Japan. This book offers an up-to-date comprehensive guide for those interested both in the geology of the Japanese islands and geological processes of island arcs in general. It contains contributions from over 70 different eminent researchers in their fields and is divided into 12 main chapters:
Geological Evolution of Japan: an Overview;
Regional Tectonostratigraphy (consisting of seven separate sections giving full coverage both to the different geographic regions and different geological ages);
Ophiolites and Ultramafic Units;
Neogene-Quaternary Sedimentary Successions;
Deep Seismic Structure;
Coastal Geology and Oceanography;
Mineral and Hydrocarbon Resources;
Field Geotraverse, Geoparks and Geomuseums (with information on travelling by public transport to see some of the great geological sites of Japan).
Each chapter includes the unique contribution of an extensive aid to the written forms of geology-related names in Japanese.
