Fireworks

Fireworks Island (ファイアーワークス) is an anime-only island in the Grand Line.

The Straw Hat Pirates landed here on their way down the Grand Line, during Episode 134.

Layout
The island has a very basic shape, with a town area near the bottom and mountains at the top. There is also a graveyard near the eastern side of the island where Kodama's parents are buried.

Culture
Life on the island seems to revolve around the annual Fireworks Festival that takes place when the Straw Hats land. There are many shops and homes near the harbor, but the real focus of the island takes place in the mountainous regions north of there. Odama and his granddaughter Kodama live there, as well as several other Firework Launchers. The family has been making fireworks for 400 years.
