Thank you for your reply. I am in two minds and Fiji is still to my experience the main contender for origin as there is a prunus genus native to Fiji

However there are atypical aspects that could question Fiji. Inlay of bone, shell or teeth are common but not the octagonal shape? also the bark still on the stick. Also I could see a Japanese aesthetic ? in this piece .
