Avoid this beach(I wouldnt call it a beach tbh)for now - it's a real mess with tons of garbage covering the sand. Not at all ready for swimming or beach activities. Wait until they've had a chance to clean it up properly.
So here is the thing. If you go there early in the afternoon, you will see that the water is not deep and there are scary sea cucumbers/eggplants. As the tide returns in the late afternoon, the water becomes clearer and deeper. Unlike other places that close at 6, you can swim until you are tired. Please don't go early in the afternoon.
It is a calm place. The only two people there were me and a friend. I think I like it.
From Kagoshima, you can easily take a boat to Sakurajima and enjoy swimming right away. It's a small, cozy place, and there aren't many beaches in the world surrounded by a volcano like this one. ...
There's a free shower right in front of the public restroom, making it a great place for a quick swim.
If you're planning a trip to Kagoshima in the summer, this is a must-visit.
It looks like a swimming beach.
There wasn't a single person there, probably because of the time of year.
As I observed along the sandy shore, I saw small fish swimming!
Unlike city beaches, it was very clean with almost no trash or waste!
