Sea of Japan The Sea of Japan is a sea part of the Pacific Ocean, separated from it by the Japanese islands and the island of Sakhalin. It washes the shores of Russia, Korea and Japan.

Sea of the Pacific Ocean Japanese Islands Sakhalin Russia Korea Japan Sea Pacific Ocean Japanese Islands Sakhalin Russia Korea Japan Japan The northern part of the sea freezes in winter. The northern part of the sea freezes in winter.
QUESTION ABOUT THE NAMING OF THE SEA In South Korea, the Sea of Japan is called the “East Sea” (Korean), and in North Korea the East Sea (Korean). The Korean side claims that the name “Sea of Japan” was imposed on the world community by the Empire of Japan. The Japanese side, in turn, shows that the name “Sea of Japan” appears on most maps and is generally accepted.
Flora and fauna Off the coast of the Far East there is a mixture of warm-water and temperate fauna. Here you can find octopuses and squids, typical representatives of warm seas. At the same time, vertical walls overgrown with sea anemones, gardens of brown algae and kelp, all this is reminiscent of the landscapes of the White and Barents Seas. In the Sea of Japan there is a huge abundance of starfish and sea urchins, of various colors and sizes, brittle stars, shrimps, and small crabs are found (Kamchatka crabs are found here only in May, and then they move further into the sea). Bright red ascidians live on rocks and stones. The most common shellfish is scallops. Among the fish, blennies and sea ruffes are often found.

ICE CONDITIONS In the Sea of Japan, the ice cover reaches its maximum development in mid-February. On average, ice covers 52% of the area of the Tatar Strait and 56% of the Peter the Great Bay. Ice melting begins in the first half of March. In mid-March, the open waters of Peter the Great Bay and the entire coastal coast up to Cape Zolotoy are cleared of ice. The ice boundary in the Tatar Strait retreats to the northwest, and in the eastern part of the strait, ice is being cleared at this time.

Scroll through the presentation for a geography lesson for grade 5 on the topic: “Sea of Japan”
The Sea of Japan is part of the Pacific Ocean, separated from it by the Japanese Islands and Sakhalin Island.
Location: Northeast Asia.
Area: 1062 thousand km².
Volume: 1630 thousand km³.
Maximum depth: 3742 m. Average depth: 1753 m.
The Sea of Japan is connected to other seas and the Pacific Ocean through 4 straits: Korean, Sangarsky, La Perouse, Nevelsky.
Korea Strait
Sangar Strait
Strait of La Perouse
Nevelskoy Strait
The Sea of Japan washes the shores of Russia, Japan, the Republic of Korea and the DPRK.
The climate of the Sea of Japan is temperate, monsoonal. The northern and western parts of the sea are much colder than the southern and eastern. In the coldest months (January-February), the average air temperature in the northern part of the sea is about −20 °C, and in the south about +5 °C. The summer monsoon brings warm and humid air. The average air temperature of the warmest month (August) in the northern part is approximately +15 °C, in the southern regions about +25 °C. In autumn, the number of typhoons caused by hurricane winds increases. The largest waves have a height of 8-10 m, and during typhoons, the maximum waves reach a height of 12 m.
The salinity of the water in the Sea of Japan is 33.7-34.3%, which is slightly lower than the salinity of the waters of the World Ocean.
Tides in the Sea of Japan are clearly expressed, to a greater or lesser extent in different areas. The greatest level fluctuations are observed in the extreme northern and extreme southern regions. Seasonal fluctuations in sea level occur simultaneously over the entire surface of the sea; the maximum rise in level is observed in summer.
According to ice conditions, the Sea of Japan can be divided into three areas: the Strait of Tartary, the area along the coast of Primorye from Cape Povorotny to Cape Belkin, and Peter the Great Bay. In winter, ice is constantly observed only in the Tatar Strait and Peter the Great Bay; in the rest of the water area, with the exception of closed bays and bays in the northwestern part of the sea, it does not always form. The coldest area is the Strait of Tartary, where more than 90% of all ice observed in the sea is formed and localized during the winter season. According to long-term data, the duration of the period with ice in the Peter the Great Gulf is 120 days, and in the Tatar Strait - from 40-80 days in the southern part of the strait, to 140-170 days in its northern part.
The underwater world of the northern and southern regions of the Sea of Japan is very different. In the cold northern and northwestern regions, the flora and fauna of temperate latitudes has formed, and in the southern part of the sea, south of Vladivostok, a warm-water faunal complex predominates. Off the coast of the Far East, a mixture of warm-water and temperate fauna occurs.
In the Sea of Japan you can find octopuses and squids - typical representatives of warm seas. Also vertical walls overgrown with sea anemones, gardens of brown algae - kelp.
In the Sea of Japan there is a huge abundance of starfish and sea urchins, of various colors and sizes, shrimp, jellyfish, and small crabs. Bright red ascidians live on rocks and stones. The most common shellfish is scallops. Among the fish, blennies and sea ruffes are often found.
