Tokyo Live Cameras in Japan — 13 official webcams
Two very different sets: six cameras on the volcanoes of the Izu Islands, and seven on the lower Arakawa. Ocean 100 km south of the city, and levees in the east of the ward area.

Sample August 2026
Izu Oshima
Oshima, Tokyo · Volcano · Sea
The 1986 eruption evacuated every resident off the island. The camera looks at the Mount Mihara caldera from the northwest rim.
-
Sample August 2026
Niijima
Niijima, Tokyo · Volcano · Sea
An island of white rhyolite, long quarried for building stone. The camera faces neighbouring Shikinejima.
-
Sample August 2026
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.
-
Sample August 2026
Miyakejima
Miyake, Tokyo · Volcano · Sea
Volcanic gas kept coming after the 2000 eruption, and islanders lived off the island for more than four years. The camera is on the southeast side.
-
Sample August 2026
Hachijojima
Hachijo, Tokyo · Volcano · Sea
An island made where two volcanoes, Hachijo-Fuji and Mount Mihara, joined. From the high ground the camera sits on, slope and sea run on together.
-
Sample August 2026
Aogashima
Aogashima, Tokyo · Volcano · Sea
A double caldera with another hill rising inside the first. It has the smallest population of any inhabited island in Japan.
-
Sample August 2026
Goshikizakura Bridge
Adachi, Tokyo · River
17.1 km from the mouth. A double-deck bridge carrying the Kawaguchi expressway over the river; at night the pier lighting stretches across the water.
-
Sample August 2026
Above Nishiarai Bridge
Adachi, Tokyo · River
13.8 km from the mouth, looking upstream of Nishiarai Bridge from the left bank. Tower blocks line the far side and the water picks up their lights.
-
Sample August 2026
Horikiri emergency wharf
Katsushika, Tokyo · River
9.8 km from the mouth. A landing built to move people and supplies by boat when roads are unusable. In normal times it is an empty, quiet waterfront.
-
Sample August 2026
Above Hirai Bridge
Edogawa, Tokyo · River
6.4 km from the mouth, looking upstream of Hirai Bridge from the right-bank levee. The low viewpoint puts the full width of the river on screen.
-
Sample August 2026
Below Metropolitan Expressway Route 7
Edogawa, Tokyo · River
4.3 km from the mouth, downstream of where Route 7 crosses. The near bank is high floodplain thick with reeds.
-
Sample August 2026
Komatsugawa emergency wharf
Edogawa, Tokyo · River
2.4 km from the mouth. Central Tokyo's towers stand beyond the far bank, and on a clear day their outlines are sharp.
-
Sample August 2026
Shinsuna emergency wharf
Koto, Tokyo · River
The marker here reads -0.5 km, the closest the Arakawa gets to the sea. This stretch is tidal, and the level rises and falls within the day.
When to watch
The island cameras are the volcanoes that belong to Tokyo, listed north to south: Oshima, Niijima, Kozushima, Miyakejima, Hachijojima and Aogashima. Every one is surrounded by sea, so there is a horizon somewhere in each frame. Aogashima has the unusual shape of a caldera inside a caldera, and is also the least populated municipality in Japan.
Island cameras live at the mercy of the weather. Fog and cloud build fast over the sea, and from the rainy season through summer the screen can stay white for days. The dry air of a winter pressure pattern gives the longest views.
The Arakawa cameras come from the ministry's Arakawa-Karyu River Office: Goshikizakura Bridge and Nishiarai Bridge (Adachi), Horikiri (Katsushika), Hirai Bridge, the Metropolitan Expressway Route 7 crossing and Komatsugawa (Edogawa), and Shinsuna (Koto) — arranged from upstream down to the mouth. Everything below the Iwabuchi Floodgate is a man-made channel, dug between the end of the Meiji era and the early Showa era to carry floods out to sea, which is why it runs so straight and wide between high levees.
Each image is stamped with the river name and the distance marker, in kilometres from the mouth. Horikiri, Komatsugawa and Shinsuna are emergency wharves, built to move people and supplies by boat during a disaster.
River cameras earn their keep in heavy rain and typhoons. Normally the water is low and the floodplain shows a wide expanse of playing fields and grass; as the river rises that goes under in sequence, so watching from Sasameba upstream to Shinsuna at the mouth shows the water arriving. On a clear day the minute-by-minute stills change little beyond a few walkers on the bank and traffic crossing the bridges.
