Cape Ochiishi Station
Cape Ochishi is a small cape located at the base of the Nemuro Peninsula in eastern Hokkaido, surrounded by sheer cliffs. In the center of the cape, there is the Ochiishi Marsh and the southernmost native habitat of the Sakai azalea, a natural monument. Most of the cape is designated as a nature conservation area.
The monitoring station is located at the southern end of the cape, on a cliff 42 meters above sea level. There is a Ochiishi fishing port and residential area at the base of the cape. Since the station is about 2 km away from those area and the air samples are taken from about 50 m above the ground level on the observation tower, they have almost no local anthropogenic influence on the observation.
