Aoga-shima is a stratovolcano forming a beautiful small 2.5 x 3.5 km island with steep cliffs in the Izu island chain, 300 km south of Tokyo.
Aogashima’s main attraction is its geologic anomaly, the double volcano. The island itself is one volcano, and another smaller volcano sits inside the caldera of it. Over 200 people live there. And yeah, it is an active volcano.
The main volcano also has steam vents around one side of it. The steam is scalding hot, and is used to power the public sauna, which is the perfect way to relax after a long day of hiking the island.
The wharf at the island’s only port, Sanbō, can handle small ships of up to 500 tons, and is unusable during time of high waves and inclement weather.
