Kenzan Island

Kenzan Island (剣山島, Kenzan-tō, Sword Mountain Island) is an island somewhere in the Grand Line, where the Teena Geena Kingdom (テーナ. ゲーナ王国, Teena Geena Oukoku) is located. This place seems to be the homeland of the Longarm Tribe, having chinese-like constructions and valleys between the mountains, that have a sword shape, but that it is where the Longarm Tribe have taken Brook and seemingly have him on display. While the Longarms in Kenzan witness the living skeleton, though in his cage, Brook was able to obtain a newspaper to learn of Luffy's exploits. As well as the fact that there is in audience to look at Brook, it seems fairly inhabited.
