The name Chiyoda (千代田) applies to at least three Japanese companies:

  • Chiyoda Kōgaku Seikō was the former name of Minolta (from 1937 to 1962)
  • Chiyoda Seisakusho, later Chiyoda Kōgaku Kōgyō, was a microscope maker which briefly produced camera lenses in 1954–5
  • Chiyoda Shōkai was a distributor from 1946
  • the wartime Bolca is attributed to "Chiyoda Kōgaku", which is probably none of the above
