The one piece manga was originally published in Japanese for sale in Japan. The English adaptation was published and distributed in the form of American magazine and graphic novels for sale in North America and Australia. Due to its success one piece was serialized on a weekly basis as an animated series so that it will reach a larger audience through television. The author had originally planned the manga to last for five years and had also planned the ending, since the story was too enjoyable he couldn’t end it in that amount of time and he himself has no idea as how long it will take to end it. Apart from those serials which are aired in television read one piece manga feature films are also produced and are released every year since 2000. Two vast oceans are used to cover the functional world in one piece; these oceans are divided by a huge mountain range which is known as the red line. The grand line is a sea which runs perpendicular to the mountain range, which divides itself into four seas the first two are north blue and east blue, the second and third are west blue and south blue. The grand line is surrounded by two regions these are called calm belts, these regions experience no ocean currents nor wind hence are the breeding ground for sea kings which are huge sea creatures. For those who try to enter the grand line calm belts form an effective barrior. For those ships which use sea prism stones would be able to mask their presence and can pass easily. In grand line open sea weather and sea currents are unpredictable however the climate is stable in the vicinity of the islands. Since the normal compasses do not work in this place it is even harder to navigate. A special compass known as a log poses needs to be used in this area.
