A river mouth is the part of a river where the river debouches into another river, a lake, a reservoir, a sea, or an ocean. The water from a river can enter the receiving body in a variety of different ways; the motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface; the river water will either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow. Alongside these advective transports, inflowing water will diffuse. At the mouth of a river, the change in flow condition can cause the river to drop any sediment it is carrying; this sediment deposition can generate a variety of landforms, such as deltas, sand bars and tie channels.
Many places in the United Kingdom take their names from their positions at the mouths of rivers, such as Plymouth and Great Yarmouth. Confluence River delta Estuary Liman
The Toyohira River is a river in Hokkaidō prefecture, Japan. It is 72.5 km in length and has drainage area of 894.7 km². It is a tributary of the Ishikari River, it supplies water to Sapporo city, the capital of Hokkaidō built on the alluvial fan formed by the river. Jōzankei is a popular attraction with onsen along the upper Toyohira. From the mountain Oizaridake, the Toyohira River flows northwards into Lake Jōzan; the Hōheikyō Dam created the lake. The river runs through the gorge. After exiting the gorge it is joined by several more rivers before turning East. Two smaller dams block the course of the Toyohira; the river flows east through the middle of the Toyohira Ward of Sapporo. As it leaves the urban area it forms the border between Sapporo and Ebetsu before emptying into the Ishikari River; the Ainu knew this river as Sapporo Pet. Toyopira was the name of a crossing point of the Sapporo River; until the 19th century, the lower course of the Sapporo River had been the same as the Fushiko River of today, emptying into the Ishikari River directly to the north.
After a flood, the river made a new course to the east. The Ainu called the remains of this old lower course of the Sapporo River Fushiko Sapporo or Old Sapporo; when the Japanese colonized the area, they used Ainu place names. They named the new capital city after the river Sapporo and named the Sapporo River after the crossing point Toyohira; the old lower course of the Fushiko Sapporo was named Fushiko River. The Toyohira Bridge was built at the crossing point named Toyopira by the Ainu. Anano River Makomanai River

Seto Inland Sea
The Seto Inland Sea known as Setouchi or shortened to Inland Sea, is the body of water separating Honshū, Kyūshū, three of the four main islands of Japan. The region that includes the Seto Inland Sea and the coastal areas of Honshū, Kyūshū is known as the Setouchi Region, it serves as a waterway. It connects to Osaka Bay and provides a sea transport link to industrial centers in the Kansai region, including Osaka and Kobe. Before the construction of the San'yō Main Line, it was the main transportation link between Kansai and Kyūshū. Yamaguchi, Okayama, Hyōgo, Wakayama, Ehime, Fukuoka, Ōita prefectures all have coastlines on the Seto Inland Sea; the Setouchi region is known for its moderate climate, with a stable year-round temperature and low rainfall levels. The sea is famous for its periodic red tides caused by dense groupings of certain phytoplankton that result in the death of large numbers of fish. Since the 1980s, the sea's northern and southern shores have been connected by the three routes of the Honshū–Shikoku Bridge Project, including the Great Seto Bridge, which serves both railroad and automobile traffic.
The International Hydrographic Organization's definition of the limits of the Seto Inland Sea is as follows: On the West. The Southeastern limit of the Japan Sea. On the East. A line running from Takura Saki in Honsyû to Oishi Hana in the island of Awazi, through this island to Sio Saki and on to Oiso Saki in Sikoku. On the South. A line joining Sada Misaki in Sikoku and Seki Saki in Kyûsyû; the Seto Inland Sea is 450 km long from east to west. The width from south to north varies from 15 to 55 km. In most places, the water is shallow; the average depth is 38 m. Hydrologically, Setouchi is not a true inland sea, being neither an epeiric body of water like Hudson Bay nor an isolated endorheic basin like the Caspian Sea. Rather, it is a marginal sea; the Naruto Strait connects the eastern part of the Seto Inland Sea to the Kii Channel, which in turn connects to the Pacific Ocean. The western part of the Seto Inland Sea connects to the Sea of Japan through the Kanmon Straits and to the Pacific through the Bungo Channel.
Each part of the Seto Inland Sea has a separate name in Japanese. For example, Iyo-nada refers to the strait between Ehime, Ōita prefectures in the western portion of the sea. There are many straits located between the major islands, as well as a number of smaller ones that pass between islands or connect the Seto Inland Sea to other seas or the Pacific. 3,000 islands are located in the Seto Inland Sea, including the larger islands Awaji-shima and Shōdo-shima. Many of the smaller islands are uninhabited. Eastern part: Awaji Island, Shōdo Island, Ieshima Islands, Naoshima Islands, Shiwaku Islands Central part: Ōmishima, Itsukushima, Hinase Islands, Kasaoka Islands Western part: Suō-Ōshima, Uwakai Islands, Hashira-jima Islands. Over 500 marine species are known to live in the Seto Inland Sea. Examples are the ayu, an amphidromous fish, the horseshoe crab, the finless porpoise, the great white shark, which has attacked people in the Seto Inland Sea. In the past whales entered the sea to feed or breed, however due to whaling and pollution, they have disappeared from the Seto Inland Sea, except for occasional lost individuals.
It is believed. After the ice age, sea water poured into a basin between the Chūgoku mountains and Shikoku mountains and formed the Seto Inland Sea as we know it today. From ancient times, the Seto Inland Sea served as a main transport line between its coastal areas, including what is today the Kansai region and Kyūshū, it was a main transport line between Japan and other countries, including Korea and China. After the creation of major highways such as the Nankaidō and San'yōdō, the Seto Inland Sea remained a major transport route. There are records that some foreign emissaries from Korea sailed on the Seto Inland Sea. Due to the importance of water traffic, regional powers had their own private navies. In many documents, these navies were called suigun, or pirates. Sometimes they were considered to be public enemies, but in most cases they were granted the right to self-governance as a result of their strength. In the 12th century, Taira no Kiyomori planned to move the capital from Kyoto to the coastal village of Fukuhara to promote trade between Japan and the Song dynasty of China.
This transfer was unsuccessful, soon after Kyoto became the capital again. The Battle of Yashima took place off the coast of present-day Takamatsu. During the feudal period, suigun seized power in most coastal areas; the Kono in Iyo Province and Kobayakawa in Aki Province clans

Overlooking Gōtsu City is Hoshitaka Mountain, or "Star Mountain", so named for the star pattern carved into the face of the mountain. According to Gōtsu legend, the star was formed by a meteor. A piece of this meteor was saved, a special shrine was built at the foot of the mountain to honor the meteor. In the winter, snowfall on the mountain creates a beautiful star-shaped pattern, visible from anywhere in the city. In the spring, white azaleas bloom to form a white star, while the area bordering the star remains green.
In the summer, in celebration of the Japanese Obon Festival, the star is lit up at night.
