Sea: 27 Live Cameras
Coastlines, straits, beaches — and underwater. Tide and swell rebuild the frame several times a day. Check the tide table, not the forecast.
What you can see
Sea cameras were installed for wildly different reasons: some watch a strait for navigation safety, some hold a fixed frame on a beach to measure coastal erosion, and some have simply been sunk underwater for visitors and schools.
What makes them interesting is that the same place changes repeatedly within a single day. A land camera shows the same view until the weather turns; the sea runs on a roughly twelve-hour tidal cycle. Some rocks appear only at low water, and some beaches double in width.
New Zealand's coastal cameras run on the opposite season to Japan's. When it is deep winter here, those are summer beaches.

Sample August 2026
Kushimoto Marine Park
Kushimoto, Wakayama · Sea · Wildlife
An underwater camera on coral and fish living in water warmed by the Kuroshio Current. Visibility changes a great deal from day to day.
-
Sample August 2026
Yumigahama Beach, Minami-Izu
Minami-Izu, Shizuoka · Sea
A bow-shaped stretch of sand in a sheltered cove. Busy with swimmers in summer; the rest of the year only the waves and the pines move.
-
Sample August 2026
Ago Bay from Mount Yokoyama
Shima, Mie · Sea
A ria coast of countless islets and inlets seen from above. Thin lines of pearl oyster rafts run across the water.
-
Sample August 2026
Kurushima Strait
Imabari, Ehime · Sea
One of Japan's three great tidal races. The pattern on the surface flips each time the tide turns, and large ships pass through in single file.
-
Sample August 2026
Whakatane coast
North Island · Volcano · Sea
A monitoring camera looking from the Bay of Plenty shore out towards Whakaari (White Island).
-
Sample August 2026
Seto Inland Sea from Mount Washu
Kurashiki, Okayama · Sea · Nature
A lookout known for its scatter of islands. The Great Seto Bridge overlaps the island silhouettes, and evening backlight sets the water shining.
-
Sample August 2026
Seto Inland Sea from Goshikidai
Sakaide, Kagawa · Sea · Nature
The same sea from the Shikoku side. Facing the opposite way from the Washu camera, so the islands line up differently.
-
Sample August 2026
Swans at Kominato beach
Hiranai, Aomori · Wildlife · Sea
A shallow shore on Mutsu Bay, long known as a swan arrival site. The numbers build as winter comes on.
-
Sample August 2026
Te Kaha coast
North Island · Volcano · Sea
A camera on the eastern Bay of Plenty coast watching out towards Whakaari (White Island), from further east than the Whakatane view.
-
Sample August 2026
Mount Esan
Hakodate, Hokkaido · Volcano · Sea
At the eastern tip of the Oshima Peninsula, jutting into the Tsugaru Strait. The vent field on its flank is still active, and azaleas redden the slope in early summer.
-
Sample August 2026
Izu East volcano group
Ito, Shizuoka · Volcano · Sea
A cluster of monogenetic volcanoes with small craters scattered on land and under the sea. A 1989 submarine eruption off Ito built the Teishi Knoll.
-
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
Satsuma Iwojima
Kagoshima · Volcano · Sea
An island where Mount Io gives off a white plume without stopping. Known for the iron leaching out and staining the sea around it red-brown.
-
Sample August 2026
Kuchinoerabujima
Kagoshima · Volcano · Sea
The whole island was evacuated after the 2015 eruption. Steam rises from the Shindake crater, visible even from Yakushima.
-
Sample August 2026
Nakanoshima
Kagoshima · Volcano · Sea
The largest island in the Tokara chain. The cone of Mount Otake takes up its northern half, with steam coming from near the summit.
-
Sample August 2026
Suwanosejima
Kagoshima · Volcano · Sea
An island that erupts repeatedly, throwing ash from the crater on many days. The settlement is well away from it.
-
Live video, rotating
Higashi-Harima coast
Akashi–Kakogawa, Hyogo · Sea
A sandy shore on the Seto Inland Sea. This camera shows coast rather than river, so wave height and tide are what to watch.
-
Live video, at sea only
Deep-sea research vessel Okeanos Explorer
several hundred to several thousand metres deep · Sea · Wildlife
The raw feed from a remotely operated vehicle lighting its way along the seafloor. It runs only while the ship is on an expedition and goes dark for months between. At that depth no daylight reaches, so the sky artwork on the card does not apply here.
-
Live video
Jiri and Cheongseon shore, Dadohaehaesang
South Jeolla · Sea
A beach among the many islands of the Dadohae. The tide changes how much sand there is, and how clearly the distant islands show tells you how clear the air is.
-
Live video
Gaksan, Hallyeohaesang
Sacheon, South Gyeongsang · Sea · Nature
A hilltop camera over the Hallyeo waterway. The broken coastline, the islands and the boats moving between them all fit in one frame.
-
Live video
Jukmak trail, Byeonsanbando
Buan, North Jeolla · Sea · Nature
A coastal path on a peninsula reaching into the Yellow Sea. Unlike Japan's Pacific coast, the sun sets over the water here, so clear evenings show it well.
-
Live video
Hagampo, Taeanhaean
Taean, South Chungcheong · Sea
Sand and rock on the Yellow Sea. The tidal range is large, and at low tide the beach runs a long way out.
When to watch
Read them against a tide table. In the hour either side of low water, things that normally sit submerged come up. At high water the swell reaches the structures, and on a rough day you get to watch it break.
By season, the Sea of Japan coast in winter is in a class of its own. A sustained northwesterly builds the swell until whitecaps fill the frame even on a clear day. The Pacific side is the reverse — calmer in winter, with air clear enough to show distant islands.
For time of day, around sunrise and sunset. The sea reflects the sky, so the colour shifts harder than it does on land. Point a camera near the horizon and you get the sun coming out of the water, or going into it.
