Hocotate is Captain Olimar's home planet. It has an atmosphere of carbon dioxide and methane. The name Hocotate comes from Nintendo's headquarters' street address. It is near other planets, which may or may not be inhabited. It possesses 2 sets of visible rings, which are probably composed of dust and rock, like most astronomical rings. Their presence could mean that Hocotate is a very large planet, which contrasts with the small size of its people. The planet also has two moons and is somewhat barren and rocky, with few plants, but the daytime sky is so transparent that stars, galaxies, and the planet's rings and its moons can be seen during the day; possibly indicating that the atmosphere is very thin.
The people of Hocotate are about the size of a quarter and can only breathe methane. Oxygen is poisonous to people from Hocotate. The technology is very advanced, as even quarks have been utilized (seen in the Gluon Drive part in Pikmin 1). With such advanced technology, it is ironic that comparatively primitive, human-made objects are considered treasures there. Also, Olimar has apparently publicized the location of the Pikmin Planet. This can be inferred due to numerous references to "other travelers". As it is doubtful that these are Pikmin (who are not intelligent enough to even speak), the only possible choice is that they are people of Hocotate.The people on this planet speak an unknown language. It could possibly be a language spoken on Earth in: 1.: an unaltered state; 2.: spoken backwards, or 3.: extremely modified. Of course, these are all assumptions, and Nintendo has not mentioned anything about its origin.
