Here's one you can watch right now, because Crunchyroll started streaming the Nobunaga Concerto J-Drama last night at 10:00pm Pacific Time.
Nobunaga Concerto—starring Shun Oguri, who recently played the lead in Ryuhei Kitamura's live-action Lupin III film—is available in the following territories: USA, Canada, Central and South America including Caribbean, European countries excluding Russia, South Africa, Australia and New Zealand.
Saburo, a high school student is flung back in time to the Sengoku Era. In the past, he meets a young, but sickly Oda Nobunaga, one of Japan's greatest warlords. Unable to shake Saburo's uncanny resemblance to himself, Nobunaga asks Saburo to take his place as war lord. Equipped with knowledge from the modern era, will Saburo be able to unite Japan?
The television adaptation of Ayumi Ishii’s historic manga begins this fall! Critically acclaimed actor Oguri Shun (Hana Yori Dango) will play the role of the time traveling Saburo opposite Shibasaki Kou (Galileo), who plays Kicho, his wife. They are joined by actors Takayuki Yamada (Densha Otoko) and Osamu Mukai (Hungry!).
