When a shared door of a building that I’ve been staying for now ( some place in O-city of Hokkaido in Japan ) is closed, a very noisy shocking sound is caused.
As such unpleasant shocking sounds were caused many times a day, I searched problems of dwelling with such defects for ‘faulty residences’ (欠陥住宅) or ‘stigmatized objects’ (事故物件).
At that time, the site of Oshima Teru ( http://sp.oshimaland.com ) was indicated in high ranks of searched results.
I found out this site through above circumstances.
By the way, I heard that the meaning of ‘a large-sized island exposed to something such as a visual or monitoring system, some radiation is implicated in the name called Oshima Teru.
