A couple rented it in the latter half of December 2021. I wanted to spend a quiet time, so the conditions were good with only nature around me. The rooms and gardens were beautifully maintained.There was a lot of pumice and trash on the private beach. They may have gathered because it was winter and the wind and waves were strong.Around 23:30 one night at the end of the year,When I went out to the balcony of my dorm to cool off, there was a bench placed near the sandbox on the premises, but I was surprised to hear a rustling sound coming from the bushes directly behind it, and when I turned my attention to it, I saw a pale light? fireball? A light that looked like this flashed across toward the gate that closed off the premises. Immediately after witnessing the sighting, I wondered if there were any humans out there pushing through the bushes from the direction of the ocean at this time of year. I thought it was strange, but when I thought about it later, I squinted my eyes at the object that appeared from the bushes and did my best to make out the object, but it was raining heavily and it was more like a ball of light than a human figure. I remember it as just something passing right in front of me, and I still don't understand what it was.It is located directly behind the Blue Cave, and it was hard to believe that something would appear from the sea in the middle of the night and in such bad weather. This dormitory has high security and surveillance cameras, so it is likely that the incident was captured on video, but as we are guests, we ended our trip without checking or reporting anything. .Maybe it's a place where strange things like this can happen.Also, I guess it can't be helped since it's Okinawa, but there were cockroaches living in the rice cooker, so be careful! If you find one, please contact us immediately to have it changed!
