In Tokyo Bay, there is a 1,650-hectare tideland called Sanbanse, located near Funabashi Seaside Park in Chiba Prefecture. With abundant tidelands stretching along its shores, Tokyo Bay used to be one of the country's best fishing grounds. However, rapid industrialization changed that. By the early 1980s, 22,000 hectares of the bay's tidelands, accounting for 19 percent of the entire bay, had been reclaimed. The only tidelands remaining are Sanbanse and one called Banzu in Kisarazu, Chiba Prefecture. The overall catch taken from the bay, including the popular stone flounder, has plummeted as a result.
