In 1966 the first translation of Captain Future novel (Captain Future and the Seven Space Stones) was published under Hayakawa SF Series (Paperbacks) following two translations in paperbacks. Between 1970s and 1980s all Captain Future novels were translated under Hayakawa Bunko SF (under Bunko size, smaller size of paperbacks like Reclam Books). All of them were translated by Masahiro Noda. But in early 1990s all of them were out of print. In 1995 five Captain Future novels were republished with new covers.
