The core issue is that CMatrix doesn't control which font your terminal emulator uses to draw characters. Your terminal application (like GNOME Terminal, Konsole, or Alacritty) relies on your system's installed fonts to render text. When you run cmatrix -c , the program sends a stream of Japanese Unicode characters to the terminal. If your terminal's default font doesn't support these characters, it fails to draw them.
Unimatrix allows you to specify exactly which Unicode character blocks to use. To use (characters ranging from 0x30a0 to 0x30ff ): unimatrix -c katakana Use code with caution. To mix Katakana and Hiragana : unimatrix -cc jp Use code with caution. To customize custom ranges (including Kanji): unimatrix -u "30A0-30FF 4E00-9FAF" Use code with caution.
Some users have also had success by installing the fonts-vlgothic package (a popular Japanese font) or fonts-ipafont .
However, for those who want an experience truly faithful to the film, a problem arises. The default characters, usually standard Latin letters and numbers, just don't capture the aesthetic of the movie's code. The original cinematic effect uses a dense stream of mirrored, half-width Katakana characters. So, how do you get CMatrix to display these Japanese characters? What at first seems like a simple task opens a fascinating and often frustrating rabbit hole. cmatrix japanese font
Mono spacing matters. Ensure you select a "Mono" version of the Japanese font, or the rain will flicker and jitter as character widths change.
: Many standard binary versions of cmatrix are compiled without wide-character support. If you are experiencing issues, you may need to compile from the source and link against ncursesw by modifying the Makefile to include LIBS = -lncursesw .

cmatrix is a classic terminal program that simulates the iconic green "digital rain" from The Matrix movies. By default, it uses standard ASCII characters. But what if you want to make it look more authentic to the films’ Japanese-inspired on-screen code? Or just want a cooler, more complex visual effect?
