Just north of Nagoya in Gifu Prefecture is the small town of Inuyama (lit. ‘Dog Mountain’). In summer the Kiso River features night Ukai cormorant fishing, where the birds dive down by flaming torch light, pick out the summer fish known as Ayu and then disgorge them onto a waiting boat.
On a hill overlooking the town is Inuyama Castle, one of the oldest surviving castles in Japan, constructed in 1537, and one of only twelve original castles to survive intact. It is also, I believe, the only privately-owned castle in Japan.
