Wow you can read Japanese, I didn't know that!
I put it through Google Translate, then isolated the individual sentences to get a more accurate reading of what it said.
ちょっと聞くだけで、なぜカラパキアンに口がないのですか？彼らはどのように話すのですか？ ->
Just a moment to hear, why does not Kalapakian have a mouth? How do they talk? ->
“Just a moment to ask“, “Why does not Carapacian have a mouth?“ ” How do they talk?”
Google Translate can be messy at times but if you know how to work around it, it’s a good tool.
Why does carapacian become kalapakian?
Because of the way the Japanese alphabet is composed. While Kanji represent concepts and words, Hiragana and Katakana are what’s most directly translatable to the western Alphabet- Except, Hiragana and Katakana are syllabic systems.
Where the English Language uses A B C D E… The Japanese Language has composite Syllables and vowels. A I U E O, Ta, Chi, Tsu, Te, To, Ka, Ki, Ku, Ke, Ko, and so on, with ‘N’ being the only single consonant. Hiragana is for words in general, while Katakana is an equivalent system made pretty much to use foreign words (As far as I understand it).
Now, Carapacian is not actually a word. It’s a made-up term for the Prospitians and Dersites, you could localize it as whatever the word for ‘Carapace’ is in Japanese, but they didn’t and just went for the word in the comic, Carapacian.
The thing about Japanese is, you have to approximate the sound of the word in whatever language it’s written when writing it in Katakana or saying it, transforming it to how you’d phonetically say it in Japanese. Carapacian becomes カラパキアン, at least in the way they wrote it. You could make a case for maybe different spellings since it’s not a standard word, or maybe this is the spelling the fan-translation in Japanese gave to them? I have no idea. But the character for the hard C ‘Ca’ sound in Carapacian is Ka. And there’s no distinction between L and R sounds in Japanese, you effectively use Ra, Ri, Ru, Re and Ro for L sounds as well. So since Google Translate has no idea what ‘Carapacian’ is, it just randomly assigns it an L instead of an R because it could be either.
And so, C-A-R-A-P-A-C-I-A-N becomes KA-RA-PA-KI-A-N, and Google Translate interprets the ‘RA’ as ‘LA’ arbitrarily. (In fact, while translating the whole sentence showed Google Translate saying ‘KaLApakian’, translating カラパキアン without anything else yielded ‘KaRApakian’, so you can’t get more arbitrary than that. Thanks Google).
At least as far as my understanding of Japanese goes.
