Inage Seaside Park Pool to Open on July 11, 2026 (Sat)!

World Park Co., Ltd. (Headquarters: Chiba City, Chiba Prefecture; hereinafter "World Park") announces the start of summer operations at Inage Seaside Park Pool and the opening of the "Inage no Hama" seawater bathing area within "SUNSET BEACH PARK INAGE*" in 2026.

*"SUNSET BEACH PARK INAGE" is the affectionate name for the area and facilities within Inage Seaside Park that World Park is leading the revitalization of.

This year's pool operations will strengthen collaboration with Inage no Hama, aiming to create a summer leisure space that combines "pool," "sea," "sports," and "food"—enjoyable for families, youth, and local residents alike.

2026 marks the 50th anniversary of the opening of Inage no Hama, and next year 2027 will see the Inage Seaside Park Pool celebrate its 50th anniversary as well. To pass on the long-loved charm of this seaside destination to the next generation, this year's INAPOO will go beyond the pool alone, promoting enjoyment of the entire Inage coastline.
