>>1283019>>1283111The problem is that once you get out of standard schooling in Japan, you gravitate towards what kanji / terms / etc. you feel most comfortable with, as does most of the population. Therefore, the 2k~ kanji they teach you throughout all the years will be enough to get you through life with no problem. An issue arises out of this though, when you get bored writers who have a boner for the characters and start REALLY getting into it, especially if they center their lives around academia. You end up with cases where they start picking up obscure kanji or lesser-used readings to make their work appear more flowery (it's a close approximation of purple prose in English) and educated, to the point of refusing to use loanwords to describe new concepts in some cases, so you have amateur writers essentially making their own Finnegan's Wake in Japanese. As a result, you'll have incidents like Aqua's bust description or Suisei getting caught up on something, much like how if someone who's an English speaker might drop a term like "discombobulate" on someone who isn't that well-read in comparison. English has a TON of words for practically everything, we generally don't use them because their uses are so obscure. There's words like jumentous, which describes the smell of horse urine, to noctambulist, a trumped-up phrase for a sleepwalker. I will like to make a note that spoken Japanese is incredibly easy in comparison and that Kanji honestly hurts the learnability of the language because some sounds are very much attached to specific concepts that are immutable, but when written with different radicals, make them sound so apart from one another. It's why Mori could survive in Japan as a basic bitch N4.5 for so long, since spoken Japanese is pretty easy to pick up the basics on.
There's a reason why loanwords are so heavily used in Japanese - trying to establish new characters or reusing old ones for new, arising concepts is a nigh impossible task since referring to katakana and hiragana is much easier, since you don't have to be schooled to learn the kanji. There's even been a push in the academic world for foreign college professors to not have katakana in their names, because it often leads to too much confusion for both the professor and the student because of phonetic limitations.
