Geothermal unity among multiple onsen areas on the Izu Peninsula, Shizuoka Prefecture. Shared volcanic geothermal source from the Izu eastern volcanic zone creates individualistic spring communities with varied mineral compositions and temperatures. Operating as a network rather than isolated sites, these springs integrate earth science tourism education with thermal therapy, developing as an advanced caldera landscape tourism model.

Collective geothermal region of multiple hot springs distributed across the caldera topography of Izu Peninsula, Shizuoka: Izuyama, Izunagaoka, Shuzenji, and others. Unified geological geothermal resources form independent onsen towns. From Edo period, recognized as a unified 'hot spring zone' through geographic knowledge systems. Connection with modern geology creates intersection of onsen and volcanology knowledge. Tourism consciousness emphasizes underground physical connections over surface network integration.

A geothermal network formed by multiple hot spring towns distributed across Izu Peninsula, Shizuoka (Shuzenji, Ito, Izu Highlands).
