Narugo (also known as Naruko) volcano is a caldera NW of Sendai city, northern Honshu, Japan. There is only one known historical eruption from Narugo volcano, which was in 837 AD.
Katanuma crater lake is one of the most acid crater lakes of Japan, with a pH of 1.6. Shurado crater on Toyagamori lava dome west of the lake has fumaroles that emit water vapor and SO2. Solfataras are also found on the western shore of Katanuma, and sulfur is mined from sediments on the lake floor.

Background:

The poorly defined 5.5 x 7 km wide caldera formed during eruptions about 73,000 and 45,000 years ago. It contains a cluster of 4 dacitic lava domes of Holocene age surrounding the 400-m-wide lake-filled Katanuma crater. The highest of the low, but steep-sided lava domes, Oga-dake, lies SE of the lake and reaches only 470 m above sea level. Oga-dake and Kurumiga-dake domes are capped by conglomerates and mudstones uplifted during dome growth.
