A YouTube video of a Japanese news segment about the new ornaments is embedded on this page.
By the way, here’s an explanation about shachihoko courtesy of Wikipedia:
“A shachihoko (鯱鉾 or 鯱) or shachi (鯱) is an animal in Japanese folklore with the head of a tiger and the body of a carp. It was believed that this animal could cause the rain to fall,[why?] and as such, temples and castles were often adorned with roof ornaments (shibi) crafted in the form of a shachihoko, in order to protect them from fire.”
