The 23rd UN Conference on Disarmament Issues – in Matsumoto: Memorial Event.
The Hisen/Tomoiki Film Festival is being staged at the Performing Arts Centre next to NHK on Eki-mai Dori (walk up the main street from the station for 10 mins, on your right, opposite Coco’s restaurant).
This is an NPO event which friends of mine are involved with promoting. Here is an English version of the flyer.
I believe there is a March for Peace on the 27th, incidentally, making its way from the park by Buena Vista hotel to the castle from 6pm.
