Japanese IME for ARM?

Hello everyone. I read this very interesting thread regarding Japanese IME enablement to its entirety and tried to replicate both ibus-mozc-ut and fcitx methods, but it seems a lot of the dependencies needed are either not ARM-supported or simply not found. (I keep getting a “target not found: bazel024” error) Options seem rather narrow for the Raspberry Pi 4.

Any advice would be graciously appreciated, thank you for your time.

fcitx is in the repo though, but yeah, the mozc stuff might be hard.
