It's a tie!

From Anime News Network:

“The Asahi Shimbun paper has announced the winners for the 13th Annual Tezuka Osamu Cultural Prizes this weekend. For the first time, two manga titles shared the Grand Prize: Fumi Yoshinaga’s Ōoku: The Inner Chamber, and Yoshihiro Tatsumi’s A Drifting Life.”

One’s already been released in English, and the other is due out in August. Good times.
