What Travellers Say
Reviews Summary
Visitors praise the Obitsu River Estuary Tidal Flats for their vast, natural beauty and the unique experience of exploring the rippled sand patterns at low tide. It's a place offering 'natural healing' with opportunities for bird watching and scenic views of Tokyo Bay. However, the lack of facilities and the need for careful preparation are frequently noted.
"First visit, March 4, 2021
I visited in search of natural healing.
Since March 4th is a mid-tide, with a moderate tide, I left home with high expectations.
Low tide is at 1:22 PM, and when I arrived about an hour before, the tide had already receded far enough offshore
The tidal flats, with their rippled sand patterns, came into view right before my eyes. 😸
I strolled around the area for a while.
Offshore, I could see the underwater telegraph poles and lifeguard huts of Kutsuma Beach.
Looking toward Kanagawa Prefecture, I could also see the Aqua-Line and the Wind Tower.
I also spotted foot crabs in the waterways along the way, which was very soothing.
Exploring the richness of nature helped me relieve some of my pent-up stress. 😸"

"The approach road is narrow, so be careful if you're coming by car. There is no parking lot near the entrance, but there are a few parking spaces. There are also no vending machines nearby, so you'll need to bring food and water with you. From the entrance, you can only get there on foot, which seems quite intimidating, but once you reach the beach, you'll be amazed by the spectacular views that await you. I think it's definitely worth going."
