Miyamoto Musashi/ 宮本武蔵

Mamoru Oishi from his praised but not commercially successful Sky Crawlers will be directing Studio IG movie on most famous Japanese duelist, Miyamoto Musashi. Musashi who wrote treatise on swordmanship known Book of Five Rings, said to have won 60 duels against famous martial artists in Japan. Studio IG has made excellent chambara series "Guardian of Water Spirit" or Seirei no Moribito should be able to rival another excellent chambara movie released last year, Sword of Stranger animated by Studio Bones.

Due for release in early summer 2009, the title would be 宮本武蔵―双剣に馳せる夢― / Miyamoto Musashi - Futaken ni Haseru Yume (Miyamoto Musashi – A Dream of Victory with Two Swords).

Perhaps this will talk about his exploits when he fought the Yoshioka school where he is forced to use dual sword in mortal combat against whole school. The ending might be where he went one on one against a renowned rival, Genryu Sasaki Kojiro.
