SEGA had their own stream inside what looked like a noisy elevator during E3 where they showed off a few different things and one of those was a new Yakuza 0: Legends with a bit of gameplay in it.
Honestly, the SEGA stream was a weird one, it was noisy, looked like it was inside an elevator, showed old gameplay of Dawn of War 3, promoted some Sonic events while not showing any new Sonic games, but they did show a new Yakuza 0 trailer which looked pretty promising.
It was announced in December 2014 and the new Yakuza trailer shows off a bit of story but the main focus lies on the gameplay which looks rather smooth and overall "Japanese", as someone who haven't played any Yakuza games I have to say it looks interesting. Check out the trailer above and decide for yourself.
