Geological summary
Naruko is a poorly defined, 5.5 x 7 km caldera NW of the city of Sendai. Formed during eruptions about 73,000 and 45,000 years ago, it contains a cluster of four dacitic lava domes of Holocene age surrounding the 400-m-wide lake-filled Katanuma crater.

From Wikipedia
Naruko is a stratovolcano located in Ōsaki, Miyagi Prefecture, Japan. The volcano consists of a 7 km wide caldera with several lava domes. The summit of the 470 m high Mt. Kurumigatake is one of the four lava domes located in the center of the caldera. The volcano is well known because of its relationship to the Naruko Hot Springs Villages. However, its lack of well-defined features makes it difficult to recognize for a casual observer. The Japan Metrological Agency considers Naruko to be an active volcano.
