Nemuro Hanto Chashi Ato Gun




Nemuro Hanto Chashi Ato Gun is a group of forts (Chashi) spread along north shore of Nemuro peninsula and is the 1st “castle” in the 100 Meijo book. Nemuro Peninsula is a long, narrow peninsula in the far eastern part of Hokkaido and it is believed that these forts were built in the 16th to 18th century, but the purpose is not completely clear. The forts were primarily built at the edge of cliffs along the Okhotsk Sea. There are 24 sites that are collectively registered as a national historic site and are shown on a map in the 100 Meijo book; however, most are inaccessible and hard to locate. There are two locations along Route 35 on the northern coast that have a sign and a small parking lot. There are no remaining structures and only circular grass-covered mounds where there were once clay walls and dry moats.

Visit Notes

The 100 Meijo stamp can be found at a small museum south of Nemuro City. It is too far to walk.

Apparently this one Chashi specifically is the Notsukamafu-chasi, or Nokkamafu-chashi. The only other open to the public is the Wonnemoto-chashi. According to this map I found: https://blog...789c6495.jpg
