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 artificial coastline serves as a major leisure hub easily accessible from urban areas. The park is a multi-functional space that hosts a yacht harbor, ball games, tennis courts, multi-purpose plazas, and a museum that preserves local history. It is an ideal location for activities ranging from swimming and picnics to sports, cultural learning, and BBQs.
The foundation of this park, 'Inage no Hama,' was a project designed to restore the sandy shores lost during land reclamation. Completed through construction between 1975 and 1976, it holds a significant place in history as the first artificial beach in Japan, second only to the Monte Carlo-Laroche coast in Monaco. Additionally, the 'Inage Memorial Museum,' established in 1984 to commemorate the completion of the Inage Seaside New Town development, offers exhibits that tell the story of the region's growth and development alongside the park.

The park features a wide variety of facilities. First, the vast 'Inage no Hama' becomes a lively swimming area during the summer, supported by a professional life-saving system for safety. Second, the 'Inage Memorial Museum' offers permanent exhibits on the 1st floor, meeting spaces on the 2nd floor, and a 3rd-floor observation room providing a 300-degree panoramic view of the sea. Visitors can also experience traditional tea culture at the 'Kaiseian' tea house located within the nearby Japanese garden. Furthermore, the park is well-equipped for active lifestyles with a yacht harbor, all-weather tennis courts, baseball fields, soccer fields, and indoor sports facilities.
Summer (swimming season) 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 to autumn, the grass lawns and picnic areas are popular spots to relax while feeling the sea breeze and sunlight. In the late afternoon, the scenery changes beautifully, making it a perfect time to walk along the wooden decks facing the ocean. Please note that the use of BBQ facilities is subject to specific seasons and time slots, so advance verification is required.

A diverse range of activities can be enjoyed here. Around the yacht harbor, you can experience marine leisure, while the sports facilities like tennis and soccer fields are perfect for active enthusiasts. For those interested in dining, BBQ facilities are available (reservation required); please note that open flames are prohibited, but cooking with BBQ grills is permitted. The park also provides cooking areas, water points, and vending machines for convenience. For 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 facilities. Within the park itself, nature-rich walking paths like 'Iso-no-Matsubara' and 'Omoide-no-Mori' allow visitors to enjoy a stroll amidst coastal vegetation. The area is also well-known among sports fans due to its historical connection with the training facilities of the Chiba Lotte Marines baseball team.

Preparation is key for your activities. Please bring appropriate clothing and footwear for swimming or sports. If you plan to use the BBQ facilities, ensure you follow the rules regarding prohibited open flames and bring/rent the necessary equipment. For payments, cash or electronic money (transportation IC cards) are recommended for vending machines and various facilities. When visiting the museum or art galleries, please respect photography restrictions and general etiquette to protect cultural assets. While many paths are accessible, some areas may have slight unevenness, so travelers using wheelchairs should check the terrain in advance.
