Reviews Summary

Visitors find Katsuura Undersea Park a unique spot for its dramatic coastal views and the intriguing, albeit inaccessible for some, undersea observatory. While the observatory offers a peaceful glimpse into marine life, sightings can be inconsistent. The park is appreciated for its natural beauty and historical observatory, though accessibility is a significant drawback for many.

"It is a very interesting place to visit, the waves are very strong on the surface of the water and crashing against the cliff to create the beautiful gradients against it. Then once you enter the undersea observatory, it is a whole new world, very calm and peaceful to view the sea life through the small windows. This structure is build in 1955, making it 70 yr old today! What a genius idea 💡 and who would have thought of this idea back in the day! Highly recommend when you are in Chiba and one who generally appreciates nature."

Geri Q

"Hijiki harvesting is a spring tradition in Katsuura City, Chiba Prefecture, taking place during the low tide of the spring tide in March. Fishermen enter the rocky shores 磯with sickles and backpacks, working together to harvest hijiki before the tide comes in. Around the rocky shores near Katsuura Marine Park, vast hijiki colonies can be seen, and you can observe local fishermen and their families gathering the seaweed. 三月はひじき漁が見られる。"

東出雅紘

"You can see Marine creatures living in their natural habitat and great ocean views. It's not an elaborate sightseeing spot, but a good place to feel the nature of the coastal area in the countryside. You need to walk down the stairs on your legs because there is no elevator or escalator."
