My brother Nick and I went to Sagami and found an amazing haikyo with a spectacular view. It was basically a love hotel, but it had a Chinese restaurant on top. It wasn't easy, but we climbed to the top and onto the roof. The view was simply stunning. I always ask myself (even more profoundly this time): "How can such an amazing building with this kind of view be abandoned and left to rot"?
Later, my net research garnered interesting results: The building was until recently set up with an alarm, and others reported security personnel coming. Lucky us. I have read that some one who went after us was surprised by an alarm. So unfortunately, I do recommend not to go there. Please refrain from going and enjoy the video
