Inage Seaside Park is a large-scale coastal park located in Chiba City, Chiba Prefecture. Its most distinctive feature is the 'Inage no Hama,' which holds the distinction of being Japan's first artificial beach. Spanning 1,200m in length and 200m in width, this vast man-made beach serves as a major leisure hub easily accessible from urban areas. The park is a multi-functional space that includes a yacht harbor, ball games areas, tennis courts, multi-purpose plazas, and a memorial museum. It is a perfect spot for everything from swimming and picnics to sports, cultural learning, and BBQ.
The foundation of this park, 'Inage no Hama,' was a project designed to restore the sandy shores of the former Inage Coast that had been lost to land reclamation. Completed through construction between 1975 and 1976, it holds the historical significance of being the first artificial beach in Japan (and the second in the world after Monte Carlo, Monaco). Additionally, the 'Inage Memorial Museum,' established in 1984 to commemorate the completion of the Inage Seaside New Town development, provides exhibits that trace the history of the region's growth and development.

The park features a wide variety of facilities. First, the vast 'Inage no Hama' becomes a bustling swimming destination during the summer, with a dedicated life-saving system in place for safety. Second, the 'Inage Memorial Museum' offers permanent exhibits on the first floor, meeting spaces on the second, and a stunning 300-degree observation room on the third floor overlooking the sea. Visitors can also experience traditional tea ceremony culture at 'Kaiseian,' a tea house located within the nearby Japanese garden. For active travelers, the park is well-equipped with a yacht harbor, all-weather tennis courts, baseball fields, soccer fields, and indoor sports facilities.
The summer season (swimming period) is the most vibrant time, with many visitors enjoying the beach under the supervision of a life-saving club to ensure a safe environment. From spring through autumn, the grassy lawns and picnic areas are popular spots to relax in the sun and sea breeze. In the late afternoon, the scenery from the wooden decks facing the ocean undergoes a beautiful transformation. Please note that BBQ facilities have specific operating periods and times, so it is essential to check in advance.

A diverse range of activities can be enjoyed here. Near the yacht harbor, you can experience marine-related leisure, while the various sports fields offer opportunities for active recreation. The BBQ facilities (reservation required) allow for cooking using specialized equipment, as open flames are strictly prohibited. Food and drink are easily accessible via vending machines and nearby shops. For those seeking cultural enrichment, the Inage Memorial Museum and the Chiba City Flower Museum offer insights into local history and nature.
The park is adjacent to the Makuhari New City area, which is rich in shopping malls and business-related facilities. Within the park itself, scenic walking paths like 'Iso no Matsubara' and 'Omoide no Mori' allow visitors to enjoy nature and coastal views. The area is also well-known among sports fans due to its historical connection to the training facilities of the Chiba Lotte Marines baseball team.

Preparation is key to enjoying your visit. Please bring appropriate clothing and footwear for swimming or sports. If you plan to use the BBQ facilities, remember that open flames are prohibited; you must use designated equipment or check rental rules. For payments, it is recommended to carry cash or electronic money (IC cards) for use at vending machines. At facilities like the museum, please respect photography restrictions and local etiquette. While the park features paved paths, some areas may have slight unevenness, so travelers with mobility needs should check accessibility in advance.
