It sits on the island of Kyūshū. Four different areas surround this water. These areas are Fukuoka, Saga, Nagasaki, and Kumamoto. This bay is the largest one on the island. It is a very special part of the coast. Many people live near its shores.

This sea is not very deep. Its deepest point is only about 20 meters down. The tides here are very strong. These tides can move a huge amount of water. The sea has many large tidal flats. These are flat areas of mud. The Chikugo River helps make them. It carries volcanic ash from Mount Aso and Mount Kujū. This ash settles on the flats.

Many living things call this sea home. You might see mudskippers or fiddler crabs. There are also pen shells in the water. In the autumn, a plant grows by the shore. This plant is called shichimenso. It is a type of salt-loving plant. These animals and plants make the sea very lively.

People use the sea in many ways. Many harbors sit along the coast. These include Misumi, Shimabara, and Taira. Other harbors are Nagasu, Kumamoto, and Miike. There are also Kuchinotsu and Oniike. Five ferry routes cross the water. People also use the sea for aquaculture. They grow nori, which is a type of seaweed. In May, people visit Kashima for the Gatalympics. This is a fun sports event in the mud.

Nature and people are closely linked here. Mount Unzen stands tall near the sea. The Arie River flows from that volcano. The river goes straight into the bay. Some parts of the sea face changes. There is more pollution and red tides lately. People also use land reclamation to make more land. This happens even when the government asks them to stop.
