Ōyu Geyser

The Ōyu Geyser is a natural hot spring in Atami that has been fitted with a controlled system to release hot water and steam in regular cycles. The eruptions shoot upward every few minutes, creating a dramatic display of geothermal power in the town center.

The site gained prominence during the Edo period when powerful leaders visited to benefit from its healing properties. Its reputation as a therapeutic destination has persisted for centuries, making it an enduring attraction.

The geyser belongs to a group of seven hot springs that shaped the town's identity as a spa destination. Today, visitors come here to experience the raw power of geothermal activity in one of Atami's most recognized spots.

The site is accessible and welcoming to visitors throughout the day with clear viewing areas around the spring. Arriving early morning gives you a quieter experience to watch the eruptions without crowds.

The grounds hold a monument connected to early telecommunications history, marking where pioneering telephone experiments took place. This technological heritage makes it an unexpected reminder of Japan's role in modern communication breakthroughs.
