The lowest mountain in Japan, Mt. Ogatafuji is an artificial mountain, completed on “Surveying Day”, June 3rd, 1995. From base to peak, it is 3.776m tall, exactly 1/1000 the size of Mt. Fuji. Its peak is at sea level, and like the nearby Hachiro Lagoon Reclamation Memorial Water Level Tower, it represents the former lake surface of Hachiro Lagoon. Ogata Village was born from the lake bottom of Hachiro Lagoon after it was drained. Because of this, the land outside the embankment is lower than sea level. From Mt. Ogatafuji’s peak, you can enjoy the view of the reclaimed land, and also realize just how deep Hachiro Lagoon once was. There is also a triangulation point in front of the Hachiro Lagoon Reclamation Memorial Water Level Tower, which is 3.8m below sea level.
