The Washiba-Kumonotaira volcano group consists of a cluster of small shield volcanoes with possible lava domes in a remote area in Chubu Sangaku National Park in the heart of the Northern Japan Alps. Iwagokekodani, an older Kumonotaira volcano was active from about 1-0.9 million years (Ma) . The younger Kumonotaira volcano was active about 0.3-0.1 Ma. Washiba-ike volcano is younger than 0.12 Ma (Nakano et al., 2001-). Hayakawa (2009 pers. comm.) indicated that the Washiba-ike explosion crater was formed in an area that post-dates the latest Pleistocene glaciation, and produced a tephra layer consisting of accretionary lapilli and fresh volcanic bombs.

The Global Volcanism Program is not aware of any Holocene eruptions from Washiba-Kumonotaira. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Washiba-Kumonotaira 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.

Washiba-ike Crater
Washiba-ike crater lies in the foreground with the dramatic granitic peaks of the Yari-Hodaka Range in the background to the south. The sharp-topped peak on the center horizon is Yariga-take (Spear Peak), a popular climbing destination in the Northern Japan Alps. The Washiba-Kumonotaira volcano group consists of a cluster of small shield volcanoes with possible lava domes in a remote area in the heart of the Northern Alps. A tephra layer from the Washiba-ike explosion crater overlies the 6300-year-old Akahoya Ash from Kikai volcano.

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.
