Among the Nobunaga's signature specialties, those that caught my attention are the "Shoubu!" katsudon curry (gotta copy this) and the scenic "Nobunaga no Tenkatori" akamiso pork soba, but the menu is filled with desserts and take-away snacks too, the pick is up to you!
In case you're interested, the event lasts from September 1 to November 30, and the area of Nobunaga's pertinence is the Higashi-Meihan Expressway in Tokai region!
You can keep yourself updated on the releases of the meals and the scheduled busho-tai events checking out the Facebook account dedicated to the event.
--Thank you Teap for the instant translation check XD
And on a closing note, since we're talking about tourism, I'd like to pimp this website where you can get informations and reports on the various festivals dedicated to our favourite samurai, battles and historical sites, SAMURAI FESTIVAL.
I used its informations to update my page dedicated to the matsuri and events dedicated to Nobunaga, so you can check that out too.
The website mentions also recent festivals dedicated to Ranmaru or the Azai family (with a special spot for Ichi and her daughters, of course), I didn't include them on the page as there's no Nobunaga enactor there, but if you like the personalities involved it may be fun to check them out!
