I’ve been learning Japanese for the last couple of years. One thing I’ve always wanted to get working is Japanese text input on the Fedora Linux KDE Spin. It turns out, there’s a great Romaji/Hiragana/Kanji keyboard for KDE on Linux, it just takes a little configuring.
Update 7/6/2026: I’ve updated the instructions to include the new Input Method screens.
For Fedora, open Konsole and run:
sudo dnf -y install fcitx5-mozc fcitx5-kkc kcm-fcitx5 fcitx5-autostart
For Kinoite, open Konsole and run the following, then reboot to apply:
sudo rpm-ostree install fcitx5-mozc fcitx5-kkc kcm-fcitx5 fcitx5-autostart
Log out then back in
Open System Settings
Browse to Keyboard->Virtual Keyboard
Choose “Fcitx 5” or “Fcitx5 Wayland Launcher (Experimental)” and click Apply
I’m personally using the Wayland Launcher without any issues.

Right click the Keyboard icon in system tray
Click “Configure” or “Input Method Settings”

For newer versions of KDE Plasma:
Click “Add Input Method”

Search for: mozc
It should come up under Japanese. Select it, then click Add

Click Apply

For older versions of KDE Plasma:
Under Available Input Method search for:
Mozc
Then click “<” to add it to “Current Input Method”

Make sure to leave “Keyboard – English (US)” so that you can switch between the two.
Click “OK”

To switch between English and Mozc, just press Control+Space in any application.
As you type in Romaji, Mozc will convert what you type into Hiragana and Kanji, with select-able options in a pop-up.
楽しんで!
