Kozushima: 1 Live Camera in Japan — the Izu Islands
One of the Izu Islands. A Japan Meteorological Agency camera shoots from Maehama beach every two minutes. A pale bare slope sits in the middle of the green ridge.
What you can see
Kozushima is one of the Izu Islands. The camera was put there by the Japan Meteorological Agency to watch the volcano, and it stands on Maehama, a beach on the island. It is not scenery equipment.
The island's records include an eruption in 838 that raised Mount Tenjo. That is why a pale bare slope shows in the middle of the frame, cleanly separated from the green around it. The rock here is white rhyolite.
Close to half the frame is sky. The cloud is easy to read, and the mountain is correspondingly small.
The top-left corner carries the name of the site and the top-right the time the picture was taken, so you can check how current the frame is from the figures.

Kozushima
Kozushima, Tokyo · Volcano · Sea
An island where the record shows Mount Tenjo was formed in an eruption in 838. The view from Maehama beach takes in the pale rock face and the harbour.
When to watch
It refreshes every two minutes, so what you open is essentially now. It is a still image, so nothing moves; wait a little and open it again for the next one.
The camera faces southeast. Morning sun comes from beyond the frame and backlights it, so the pale slope reads best in the afternoon.
It is a visible-light camera, so the frame goes almost black once the sun is down.
The island sits in warm water and rarely holds snow. Winter air is clear and sharpens the ridge; summer brings humid spells when the whole island goes pale.
If it isn't showing
To open the Izu Islands cameras together, The Izu Islands — the agency's cameras, put there for the same purpose, from Izu Oshima in the north to Aogashima in the south.
For the largest island on its own, Izu Oshima. The agency's volcano cameras are gathered in JMA Volcano Watch Cameras, and the prefecture page is Tokyo.
Volcano cameras in Japan and abroad are all in Volcano, and what they are pointed at is written up in What volcano cameras are looking at.
