The Shiga volcanic complex immediately north of Kusatsu-Shirane volcano consists of a group of small andesitic shield volcanoes and pyroclastic cones. A large lava plateau was erupted between about 300,000 to 200,000 years ago. The latest activity occurred between about 250,000 and 10,000 years ago (Nakano et al., 2001-). The Shiga-Kogen (Shiga Plateau) area is a popular winter sports destination.

The Global Volcanism Program is not aware of any Holocene eruptions from Shiga. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Shiga page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Yokote-yama shield volcano of the Shiga volcanic complex is seen from Kasaga-take to its west. Ski trails are prominent in this summer view of the Shiga-Kogen (Shiga Plateau), a popular winter sports destination on the border between Nagano and Gumma Prefectures. The Shiga volcanic complex is located immediately north of Kusatsu-Shirane volcano and consists of a group of small shield volcanoes and pyroclastic cones.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
