Lore & Background
Hiuchigatake initially formed around 350,000 years ago. Around 160,000–170,000 years ago, it erupted, creating a large pyroclastic flow deposit. At the summit lie two lava domes: Akanagure and Mi-ike. Akanagure, the southern dome, produced viscous lava flows down the southern and western parts of the volcano about 3,500 years ago.
Reader's Guide
Hiuchigatake is significant as the highest mountain in the Tōhoku region and as a prominent stratovolcano within Oze National Park. Its only recorded historic eruption occurred on July 28, 1544, a moderate phreatic eruption at the Mi-ike Lava Dome that produced lahars and an associated tephra layer. The volcano's morphology, including its two summit lava domes and past pyroclastic flows, provides insight into its eruptive history spanning hundreds of thousands of years. Its inclusion among the 100 Famous Japanese Mountains highlights its cultural and geographical importance in Japan.
