Explanatory Note

Tokusetsukansen

iDATAj

  1. No.: It is only for the authorfs convenience without much meaning.B
  2. Names:
    Ship names during Tokusetsukansen. The navy often added gDai n Goh to the original name to distinguish the ships that have the same Kanji characters (n=1, 2 and 3). The names are only for internal use, and did not affect the registered names. See About renaming in detail. Many oceangoing merchant ships were painted their names on the hull using various system for transcribing the Japanese language into the Roman alphabet. The system was unified Kunrei-shiki in 1937. Hepburn is used on my web site as Kunrei-shiki has not gained widespread acceptance in or outside Japan.
