Tsuruga Castle is located in Aizuwakamatsu, Fukushima Prefecture, and was originally built in 1384. What you see standing there today is a replica of the original, and it has been designated as one of the prefecture's Important Cultural Properties.
A special event running from the start of October until the end of March brings the best of digital art to the castle, with a variety of projection mapping displays and bright illuminations for visitors to enjoy. The event is not just beautiful, but educational, too – there will be information about the history of Tsuruga Castle displayed via the projection mapping, and audio guides will also be available.
