An anonymous reader who sent us the tip confirmed that it was there until around the evening of July 7, Tanabata.
What’s a buoy?

Basically, it’s one of those things floating in the sea. A floating marker that tells you things like “this area is dangerous” or “it’s OK up to here.” The ones you often see are round and kind of bouncy-looking! They come in different colors too, with yellow and red being common.
Here’s the one they found↓
