This laboratory, appearing in the anime-only Land of the Sea Arc, is located in the Demon Island of the Land of the Sea. It is an experimental laboratory with many transgenic creatures contained in test pillars. Some time before the start of the series, Amachi, the lead scientist, and Orochimaru terrorised the people of the Land of the Sea by kidnapping the citizens for their deadly experiments, which included making the ultimate underwater ninja, an idea later abandoned by Orochimaru.
