The Sea Environment into the Future - Marine Park

Mr. Hitoshi Miyaguchi, Director of Marine Park

　There are a wide variety of parks, large and small in the city, but Marine Park (outside site) has a vast sandy beach and is the only park where you can experience the sea, such as clamming, swimming, and beach sports. Since its opening in 1988 (Showa 6363), it has been used by many citizens, and especially during Golden Week, it is crowded with tens of thousands of clamming customers a day. Why was such a Marine Park born in Kanazawa? Why do many people gather for clamming? Also, what kind of approach is the park promoting to protect the precious sea environment? It seems that here is a hint to pass on the rich sea of Yokohama to the next generation.

Until the Marine Park is established

　Most of the beaches in Yokohama were lost due to land reclamation projects conducted during the period of high economic growth, and in the late 1940s, it was only south of Tomioka, Kanazawa Ward. Before Marine Park was located, the coastline of this area had a white sand blue pine landscape, as seen in one of the eight views of Kanazawa drawn by Hiroshige Utagawa, `` Return of Oto Stern '', one of the eight views of Kanazawa drawn by Hiroshige Utagawa. Because it was quiet, it was crowded with people who enjoyed swimming and clamming.
　Under these circumstances, Marine Park was positioned as a park in the Kanazawa Landfill Project, which was decided as one of the city's six major projects in 1968 (Showa 43). Taking advantage of the history and characteristics of Kanazawa, aiming to create a park that could become a symbol of Yokohama, only an artificial sandy beach was opened in 1980 (Showa 63) after it was officially opened in 1988. Marine Park was born to restore the beach of Yokohama, which was popular with citizens, and to preserve it in the future.

Follow the rules and enjoy clamming.

　Marine Park has been popular with many people since its opening because it can be clamming for free clamming. Especially during the Golden Week holiday season, the most people visit it throughout the year. Immediately after the park opened in 1988 (Showa 63), there were scenes where people were filled with no room to stand up the beach.
　The main target of everyone who enjoys clamming is clams. Marine Park clams are naturally bred, so the amount of occurrence varies from year to year. In order to maintain an environment where clams can be enjoyed forever and clamming, Marine Park is working to comply with certain rules set by the prefecture so that each person who enjoys it does not "too much". This is why specialized security guards calling for thorough rules on site patrolling.
Rule of clamming
(1)Shellfish harvesting equipment that exceeds 15 cm in width cannot be used. (Joren and ninja rakes cannot be used even if the width of 15 cm or less. Specifically, please confirm on prefecture homepage (outside site). )
(2)It is not possible to collect juvenile shells of 2 cm or less.
(3)The amount of shellfish that can be harvested at a time is less than 2 kg.

Beach sports and marine sports

Windsurfing

　Marine Park is also characterized by a variety of sports experiences using sandy beaches and sea areas. There are six beach volleyball fields on the beach and a beach sports plaza where you can play beach soccer, and you can use it freely except during the tournament. In the summer, we hold a beach sports festival called “Beach Sports Festa” every year, and strive to further promote the spread of this event.
　In the sea area, you can enjoy marine sports such as windsurfing, SUP (stand-up paddleboard), and sea kayaking (you cannot enter the swimming area during the beach opening period). On the beach side, there is a paid board storage facility "Windsurfing Boathouse" that enhances the convenience of users. The sea is shallow, gentle to beginners, and the sea is waiting for your visit.

Thinking about the sea environment

　Unfortunately, the impact of changes in the marine environment due to global warming issues such as rising seawater temperatures and climate change, as well as an increase in plastic waste have been confirmed at Marine Park. Changes in the seaside environment have occurred, such as the South Sea fish that did not inhabit in the past, the amount of clams is decreasing, and a large amount of seaweed (seaweed) drifting ashore. On the other hand, citizen activities such as efforts to purify water quality and absorb carbon dioxide, promote the breeding of living organisms and increase the number of eelgrass grounds, which are also called the "sea cradle of the sea", and beach clean to maintain beautiful sandy beaches. It is becoming.
　Marine Park is also promoting a variety of initiatives related to the sea environment, such as holding “Parent and Child Lectures on the Sea Environment” and conducting surveys on actual conditions using underwater drones. Marine Park, where citizens can experience the sea directly, is a valuable place not only to enjoy, but also to think about and practice these marine environmental issues.

　Marine Park, a city park, carries out thorough daily management and practices environmentally friendly initiatives. We hope to pass on the irreplaceable rich and beautiful sea of Yokohama to the future together with everyone who values the sea and value the sea.
