I am trying to add Japanese input on my phone Android 14 (a degoogled custom ROM) and I am struggling to find anything in the settings. I’m not sure if it’s because I’m using a custom ROM and perhaps there is no default option in AOSP, but if it is and I need to download one could someone point me to some good options (preferably open-source). If I’m just being dumb a few pointers would be nice

On my Android devices, the language options are set in the keyboard settings, not in the device settings. Are you able to download a keyboard with Japanese support?
It looks like you might be able to install Mozc from F-Droid, but it also looks like it hasn’t been updated in five years. It’s actively developed on GitHub (https://github.com/google/mozc), though, so you may be able to build it yourself.
Mozc is a Japanese Input Method Editor (IME) designed for multi-platform such as Android OS …
Android is the first platform they mention, but it doesn’t seem like they share any builds, so there will probably be some manual labor involved.

Yeah I saw an outdated Mozc on F-Droid though I don’t think it’s compatible with Android 14 so indeed I might have to build.
In terms of settings if I go to system → keyboard → onscreen keyboard, then I see one called “Keyboard” and if I click on it and click languages Japanese literally isn’t on the list. I scrolled down and letter “J” is literally skipped under languages.
I noticed Google has “Gboard” on Play store so I must be using an AOSP default or one built by my custom ROM.

Update:
Did some digging and found out I am using the AOSP keyboard but apparently it doesn’t have good support for many languages so I need to install a 3rd-party keyboard.

I use Simeji. https://play.google.com/store/apps/details?id=com.adamrocker.android.input.simeji&hl=en&gl=US
I was just looking about mozc for Android and just saw this. If you’re using degoogled stuff then you probably don’t wanna use most closed source options(or so I’d assume) mozc is still very usable. For the next option you can try fcitx5 with anthy plugin for japanese IM. In Linux there’s mozc for fcitx5 too but for some reason it just has anthy in android. You can do other languages like Chinese Korean vietnamese etc with fcitx5. note: Anthy just have romaji input and japanese keyboard type kana input cause it was made for pc. for converting to kanji just use space and it’ll put the best kanji. to get a list, press space again. I made an account here just to comment this😂 (tbh I was thinking of giving wanikani a try. This pushed me to)
Oh, nice. Yeah, I’ll take a look. I would consider using a proprietary keyboard as a final resort as long as it doesn’t require internet so I can disable its network access.
