May 4 saw the release of the trailer for Sekigahara, directed by Masato Harada. Premiering August 26, 2017, the movie is adapted from a historical novel by author Ryotaro Shiba, and stars Junichi Okada of J-pop group V6 as Ishida Mitsunari, leader of the ill-fated Western Army at the Battle of Sekigahara.

Sekigahara was the decisive battle of the Warring States Period. Occurring on October 21, 1600, the victory of Tokugawa Ieyasu's Eastern Army heralded the beginning of 250 years of the Tokugawa shogunate.

The film focuses on Ishida, who remained loyal to his former leader, Toyotomi Hideyoshi (Kenichi Takito) while Tokugawa burned with ambition to take the recently unified nation for himself.
