08-Jul-2006 -- This is the only Big Zero point (10-degree confluence) in Japan. The point was located in the center of the biggest reclaimed land, named Hachiro-gata Kantakuchi.
The ways and pathes in the reclaimed land consists a maze, separated with a lot of channel and canal.
The target was in the rice field filled with water, and rice was growing. I stopped to walk into the rice field.
The closest point I could reach was 20 meters away, and GPS value was 40.00.00.0N, 188.8.131.52E.
