Due to the different cultures and languages in the world, some aspects of the Pikmin games had to be changed in each region. These changes are more pronounced in Pikmin 2, where the in-game treasures are actual items in the real word, and due to the cultural differences, not all players would recognize the objects and brands existing in the original Japanese version of the game.
There are three main game release regions: Japan, United States of America, and Europe. The Pikmin games are released all over the world, but there are only three main versions for each, one focused on each region.
The headquarters of Nintendo EAD, the Pikmin game developers, are located on Kyoto, Japan. As such, the development of each game is done in Japanese and consequentially, the first version to be released is the Japanese one. Either shortly before release or after, the game is then sent to be localized for the United States (by Nintendo Treehouse) and Europe. More than just a translation of the Japanese game, some graphics, sounds, scripts or objects may be altered in order to fit the culture of the region.
This holds true for the Pikmin games. For all three main titles, the Japanese version is developed first, and content is then altered to suit the American and European fan base. The Australian version uses the European changes.
Commonly, the words "NTSC" and "PAL" are used to describe the different regional versions of the game. These terms are, however, partially incorrect, as the words themselves refer to the color encoding systems used for analogue television. In order to play a specific version of a game, the television must match the color encoding. This has since been discredited for the Wii U onward with the use of HDMI cables. For the most part, the US uses the NTSC system and Europe and Australia use the PAL system. The boxart of the European and Australian versions of the Pikmin games also contains the word "PAL" next to the Nintendo logo, as do most GameCube and Wii games. These factors helped popularize the use of the terms "NTSC" and "PAL" to categorize the game regions, inadequate as they may be.
Other common names and terms for the region versions of a game are:
In order for the games to be enjoyed in several places along the world, the in-game text is written in a different language, depending on the version that's being played. The Japanese version of the Pikmin games has Japanese text, the US version has English text, and the European version has the ability to choose between English, Spanish, Italian, French and German. Another common change between versions is the boxart: the front normally contains a logo in Japanese or English, and the back contains text in Japanese, English, or the aforementioned European languages.
It's also quite normal for the English used in the European version to be British English, but this isn't always the case (the European name for the Armored Cannon Beetle Larva is the same in Pikmin 2, but the first word is localized as "Armoured" in Pikmin 3) – even the same game can alternate between American and British spelling.
Other types of changes can exist for several reasons. One persistent difference that became standard for the European version of Pikmin games, starting on New Play Control! Pikmin, was the rename of Wollywogs, Yellow Wollywogs and Wogpoles to Wollyhops, Yellow Wollyhops and Wolpoles, respectively. The reason for this change is likely due to Nintendo assuming that British players would find the term "wog" offensive. Regardless, the enemy reel in New Play Control! Pikmin was not updated to reflect this.
In the case of Pikmin, it was decided before the European GameCube release that skipping the sunset cutscene by pressing would be convenient, so that feature was added for that version of the game. All regional versions of New Play Control! Pikmin also allow skipping the cutscene. In addition, the Japanese version contains an option on the main menu that allows the player to toggle between a "child" mode and an "adult" mode; the former makes the text easier to read. Finally, the Secret Safe requires 85 Pikmin to carry it in the Japanese version, and 40 Pikmin in the other versions.
Because of the way screen refresh rates work, Pikmin is one of the few games that runs at a slower framerate in the European version, running at only 25 frames per second in-game, as opposed to the 30 frames per second framerate of the other games (besides Pikmin 3).
In the Japanese version of New Play Control! Pikmin, an exclusive fifth attract mode movie is present. The European and Korean versions of New Play Control! Pikmin also correct most of the sped-up enemy sounds that the Wii version of the game has, but made some Onion sound effects sped up.
There are a couple of differences that were first introduced in revision 1.02 of the Japanese version, meaning that for these points, revision 1.01 of the Japanese version is different from the US version, the European version, and revision 1.02 of the Japanese version:
During development, Pikmin 2 needed more than just a translation, so that the in-game treasures would reflect items familiar to each region's culture. An example would be the treasure with the internal name
While most treasure changes in Pikmin 2 come in the form of including items that are familiar to the players on each region, there are a few changes that have been enforced due to potential controversies. One of the most noteworthy examples is Pikmin 2 is the Arboreal Frippery: in the Japanese version, Olimar's notes hint at it actually being a marijuana leaf. In the US, this reference was removed, but the leaf's green color was kept. Finally, in the European version, the leaf changed color entirely, in order to remove any and all similarities to the drug. The reason for these changes comes from each region's views on drug-related themes.
Other differences in Pikmin 2 also exist, for varying reasons:
While not regional differences, it is worth pointing out that some treasure notes have a notably lower quality compared to every other treasure, exclusively in the European version. This is due to the numerous typos as well as the arguably confusing English. These problems were later spotted by Nintendo, and some were resolved for the New Play Control! release, in the form of typo fixes and full rewrites. For a list of such treasures, see this category.
Like in Pikmin, Pikmin 2 also has an option to swap between katakana/hiragana and kanji.
The text between the US and European versions varies quite a bit.
It is worth noting that in the pause menu, the US English and European English text for the day end notification that notifies how many Pikmin will be left behind does not include a number. All other languages do.
