OSHIRO EXPO in Kumamoto 2026

“OSHIRO EXPO” is a festival for castle enthusiasts that has been held every December at Pacifico Yokohama since 2016. Its purpose is to promote and develop castle culture while providing opportunities for castle fans from across Japan to connect and interact.

The Special Edition: OSHIRO EXPO in Kumamoto 2026 will be held as a special event at Kumamoto Castle Hall, located at the foot of Kumamoto Castle. Marking the 10th anniversary of the 2016 Kumamoto Earthquake, this event aims to serve as a gathering place where castle enthusiasts from all over the country can come together and strengthen their bonds, viewing this milestone not as a conclusion, but as a new starting point.
