Nagasu Town is located in Tamana District in northwestern Kumamoto Prefecture. Its southwestern side faces the Ariake Sea, and the town is well known for breeding goldfish and ornamental carp. The combination of coastal scenery, traditional festivals, fish farming, and local industry gives Nagasu a distinctive character.
Nagasu is also an important transportation point on the Ariake Sea. Ferries operate from Nagasu Port to the Shimabara Peninsula in Nagasaki Prefecture, providing a convenient connection between Kumamoto and the opposite shore.
Goldfish and Carp Village Square is one of the town’s best-known attractions. Visitors can see colorful goldfish and ornamental carp swimming in landscaped ponds and learn about the area’s fish-breeding industry through displays. The park is popular with families and children, and its lawns, playground equipment, and seasonal events make it a pleasant place to spend time outdoors.
The park’s Goldfish House opened in 1995 and exhibits a variety of goldfish bred in Nagasu. Visitors can also experience goldfish scooping, a traditional activity often enjoyed at Japanese festivals.
The site known locally as Botamochi-san is associated with the tomb of Tachibana Ginchiyo. Ginchiyo was the wife of Tachibana Muneshige, a military commander active from the Sengoku period into the early Edo period. Remembered for her courage and dignity, she remains a notable figure in regional history.
The tomb is a quiet place where visitors can pay their respects and reflect on the history of the Sengoku era. It is one of Nagasu’s historical attractions, complementing the town’s better-known goldfish culture.
Matobakai, also known as the Hama-yumi Festival, is held in January. This traditional event is associated with prayers for good health, safety at home, and a prosperous year. The ceremony involves shooting arrows toward a target as a symbolic act of warding off misfortune and welcoming good fortune.
The festival brings the community together and offers visitors a chance to experience a local tradition rooted in seasonal celebrations and wishes for protection.
The Nagasu Spring Festa is held in March to celebrate the arrival of spring. A market featuring local specialties and handmade goods creates a lively atmosphere, allowing visitors to discover products made in the area and enjoy the warmer weather.
The Hino Kuni Nagasu Goldfish Festival takes place in May and celebrates the town’s long-standing goldfish-breeding industry. Activities include goldfish scooping, displays of goldfish, and other events related to ornamental fish.
The festival attracts local residents and visitors alike. It is one of the best opportunities to experience the goldfish culture that has become a symbol of Nagasu.
The Noshikora Festival is held in August and is one of the town’s summer highlights. Traditional dancing, music, and fireworks brighten the evening and create a lively atmosphere.
The word “noshikora” is explained as a local expression meaning “energetically” or “with vigor.” The festival reflects the town’s vitality and offers visitors a chance to enjoy a summer celebration with the local community.
In October, the Goldfish and Carp Village Festival celebrates the beauty of goldfish and ornamental carp. Visitors can enjoy displays and related activities in the pleasant autumn weather, making it an enjoyable event for families and groups of friends.
Nagasu is widely known for its goldfish and ornamental carp breeding. The industry has developed through techniques and knowledge passed down over generations, producing fish valued for their health, color, and appearance. Nagasu’s ornamental fish are appreciated not only in Japan but also in overseas markets, making the industry a source of local pride.
Seaweed farming is another important local industry. Like other communities along the Ariake Sea, Nagasu benefits from the nutrient-rich coastal waters, which support the cultivation of flavorful, high-quality nori seaweed.
Locally produced nori is a familiar ingredient in Japanese households and an important part of the regional economy. Its cultivation reflects the close relationship between Nagasu’s coastal environment and its traditional industries.
Nagasu is located approximately 40 kilometers northwest of Kumamoto City. Much of the town is low-lying, while gentle hills extend through the inland area to the east. The southwestern coast faces the Ariake Sea, and some of the land was created through reclamation projects that began during the Edo period.
The combination of coastal plains and low hills has supported agriculture, aquaculture, and industrial development. The town’s position beside the Ariake Sea has also shaped its transport links and way of life.
Nagasu’s modern municipal history began with the establishment of the town and surrounding villages under Japan’s municipal system in 1889. These included Nagasu Town, Rokuei Village, Harakawa Village, and Kiyosato Village. Further mergers with neighboring communities took place in 1956, forming the present Nagasu Town.
Agriculture and fishing developed through the Edo period, supported in part by land reclamation along the coast. These industries helped establish the foundations of the local economy and community life.
In addition to aquaculture and seaweed farming, Nagasu has an industrial area on reclaimed land along the Ariake Sea. Major companies with facilities in the area include Japan Marine United, Hitachi Zosen, and LIXIL.
Shipbuilding and metalworking are particularly important industries, providing jobs and supporting the town’s economic development. The presence of these industries shows that Nagasu is not only a center of traditional fish breeding but also a place with a modern manufacturing base.
Nagasu Port is served by the Ariake Ferry, which connects Kumamoto Prefecture with the Shimabara Peninsula in Nagasaki Prefecture. The ferry is an important transportation option for residents and visitors, providing a practical alternative to traveling around the bay by road.
The port also gives Nagasu a role as a gateway between the two sides of the Ariake Sea, supporting both tourism and business travel.
Nagasu Station on the JR Kyushu Kagoshima Main Line is the town’s principal railway station. The local bus route operated by Sanko Bus has been discontinued, and the town’s registered “Kingyo Taxi” service is now described as its only public transportation service within the town. Visitors should check the service’s registration requirements and operating arrangements before relying on it.
National Routes 389 and 501 provide road connections within the town and to neighboring areas. The nearest interchange on the Kyushu Expressway is KikusuI Interchange. For access via the Ariake coastal road network, Miike Port Interchange is identified as the nearest interchange.
Nagasu Town brings together the beauty of goldfish and ornamental carp, traditional festivals, coastal industries, and historical sites. Visitors can enjoy the fish displays at Goldfish and Carp Village Square, explore local festivals throughout the year, discover the history of Tachibana Ginchiyo, and learn about the town’s fish-farming and seaweed industries.
With its railway station, port, ferry links, and industrial waterfront, Nagasu also provides a useful perspective on the connections between local traditions, modern industry, and transportation around the Ariake Sea.
