A new service has started from October 22th!
Grab some cool stickers when you go to Nakamachi Street after visiting Matsumoto Castle (hold on to your admission ticket stub)! You can get the first sticker by simply showing your ticket stub at Kurassic-kan or at the Nakamachi Shopping Street Association Office. You can get the other versions when you purchase/use a service or get a bite to eat and show your ticket stub at participating shops.
The campaign will last until stickers run out. See more information on this flyer:
and List of places where you can get these stickers.
