Overview (history, characteristics, attractions)
Katsuura Underwater Park is an ocean observation facility located in Katsuura City, Chiba Prefecture. It features an underwater observation tower, promenade, and trial diving and snorkeling, allowing visitors to get up close and personal with marine life and the underwater scenery, making it popular with families and tourists looking to observe nature. From the underwater observation tower, visitors can view the underwater scenery through glass, which changes with the tides and seasons, and the park also offers exhibits and commentary in collaboration with local fishing and marine environment conservation efforts.

- Experience Programs: Snorkeling, trial diving, guided underwater observation tours, etc. (May vary depending on the season and reservations required). There are often programs for beginners as well.
- Seasonal wildlife observationYou can enjoy the seasonal changes, such as tropical fish and colorful creatures in spring and summer, and on days in winter when the water is so clear you can see far into the distance.
- Surrounding coastal scenery: The coastline, with its rocky areas, coves, and fishing village atmosphere, is also an attractive photo spot.
