Mikasa! The name of the mighty Japanese battleship will be as familiar to the world's naval historians as it is now to viewers of NHK's Sunday evening drama "Saka no Ue no Kumo" ("Clouds Over the slope"). It was the Mikasa that all but decided the fate of the Russo-Japanese War of 1904-05, when it led a devastating attack on the Russian fleet in the Battle of Tsushima — a battle set to be played out with due dramatic bluster in the final episode of the NHK TV series next week.
