Worldbuilding

Don't have such a concept in my worlds, but I am curious to know why are japanese and english mandatory. Lore time.

Man, the idea of optional spoken language classes is dope, I wish I lived in your story haha

In Stargone, the largest single human territorial zone is overseen by the Universal Corporate Council (UCC), which is a loose union of megacorporations who established themselves and their zones within what would become the UCC early in the days of interstellar colonization. Within the UCC, English is the most widespread language and considered the official standard language for communicating with or among the general population. For higher status families in the management class, different corporate zones tend to have distinct upper class languages that are taught in schools in addition to English. In the Fortschrittliche Zukunftslösung (FZ) zone, German is the language of management. In the Chen Zone, a variant of modern Pyojuneo, the South Korean language is taught to the families of management. It is common in all the different corporate zones for those in the shareholding class spend considerable effort to educate their children in the management language of their zone in an effort to appear more high status. For members of the general population, it is normally seen as above their station to display a knowledge of the management language beyond basic slogans or chants.

The independent colonies for the most part speak English, although like all things regarding the colonies there is no complete uniformity. The Liefeld colony for example still speaks English, with classes taught by the I.M.A.G.E. central computer. However despite the computer's ability to teach, the generations of genetic alternation leading to mental degradation has left the Liefeld population loud, rowdy, and while capable of average conversational speech often unable to articulate complex concepts or read at a high level.

The Azonian colony are another exception to the norm, as they learn and speak Portuguese as their primary language, and only learn English in the later years of their educations so that they can communicate with outsiders. This makes them stand out as their English tends to be distinct as they are one of the few populations to learn it as a secondary rather than primary language.

The arweli, the alien race with which humanity has had the most contact, speak and are taught a language that the first humans to interact with them dismissively named "Umwelt". Young arweli are taught by their family pod, and with the addition of some level of genetic memory they tend to pick up on the language very quickly. Before the collapse of the arweli government, young arweli would be sent to large academies to receive formal education that expanded on what their pod had taught them. While other arweli languages are known to exist, Umwelt was the language of the arweli central government and military before it collapsed, making it by far most encountered by humans. Almost no humans are able to to decipher the various calls and croaks. Arweli on the other hand tend to be able to pick up human languages, although without surgical modification they are unable to speak them. After the war ended, it was not uncommon for arweli living in mixed areas with humans to have surgery to implant devices to modify their vocal cords to be able to speak human languages.

English primarily, then we need 2 years of an extra foreign language in order to graduate

I've been like waiting for years for this exact question. My story is about radio astronomers from two different human colonies with very different cultures having a conversation across light years using radio telescopes. Because of cryogenic suspended animation and the vast time scales of interstellar travel and terraforming, one society is a lot like a more technologically advanced modern America while the other has had thousands of years to diverge and their people are genetically altered.

The people on that world speak a conlang I invented derived from modern english. On the other world, the people speak English and the preservation of other languages is relegated to the most dusty and underfunded halls of academia. On the societal (and government) level, they weren't expecting to actually contact anyone else. Partly because their version of fundamentalist Christianity believes Earth was destroyed in the End Times, Jesus himself physically manifested to watch over their ship while they were in cryosleep and they're living in the Promised Land prepared for them by God, so obviously there's no one else out there. It causes a lot of social and political upheaval when they not only contact someone but the people they contact have a much nicer planet and much more peaceful society than they do. So suddenly linguistic anthropologists, of which there are like three, plus a handful of grad students, become very relevant.

“Greetings to whomever it was that just contacted us from the star we've designated Home Sun Candidate Number Two. We are the Citizens of Aedon and my name is Mairee the Windfly. I'm a star listener at the Tropical Observatory on Lumona Island where we've just finished building a large radio instrument we call the Bigger Bowl. Your signal is causing a LOT of excitement here right now. We're broadcasting from the fourth planet orbiting our sun, which is in a binary star system 4/25ths of a sun transition away from you. We can't understand a word you're saying, but we can tell you're human, like us. We are sending for a scholar of Ancient English right away who can hopefully help us translate. Please don't stop transmitting. Please keep talking to us. We want to hear what you have to say.”
