The Hachiman Matsuri in Omi-Hachiman is held annually on April 14-15. I saw it for the first time on April 14, 2011 when they set fire to giant torches near Himure Hachimangu Shrine. Very impressive festival.
On April 15, they have taiko drum processions. But due to the Tohoku disaster this year, the taiko drums did not appear. So I didn’t bother to see the festival on the 15th. Maybe next year. Google Map
