The beach is not appealing to beach goers or sunbathers due to the lack of easy access. Thus, local officials don't spend to much effort or dedicate many resources to keeping the beach clean of debris that washes up on shore.
The sand is pretty much like most beaches on the Bay of Shonan: sticky and black.
For these reasons, this mostly deserted beach is great for fishing, or for playing catch and disk with your dog since there are no other beach goers in sight except for a lone fisherman casting nets.
On a clear day, you might even be able to catch a glimpse of Mt. Fuji in all her glory. Regardless, I like this beach a lot for the simple reasons that it is not rocky, and that there are no crowds!
