The Canterbury Japanese Society and Christchurch Kurashiki Sister City committee members noticed two plaques had been taken from the Kurashiki Garden when they were completing their monthly working bee.
The first plaque, which was secured to a rock, represents the 40th anniversary of the relationship between Christchurch and Japan.
The second plaque was donated to the gardens and installed onto a shade house used by people working in the gardens to rest in.
Christchurch Kurashiki Sister City committee member David Bolam-Smith said it was devastating to see the plaques were missing, as they represented the friendship between the committee and Japan.
“It must have been quite an effort, it was secured to a rock,” Bolam-Smith said.
“I have no idea how they did it.”
He said it was frustrating as committee members had spent a lot of volunteer hours making the gardens look nice.

He said he has contacted Christchurch City Council about reporting the missing plaques to police and hopes someone will return them.
