If you don't want to recompile the original C code, several modern "clones" already have this built-in: CMatrix-Katakana : A specific fork designed to add these characters.
Once the Japanese font is rendering correctly, you can manipulate cmatrix to create visual art.
Mono spacing matters. Ensure you select a "Mono" version of the Japanese font, or the rain will flicker and jitter as character widths change.
To make it look exactly like the movie, you want only Katakana (often reversed) and digits. The best way to achieve this is by using a version of CMatrix that allows custom character mapping or by simply relying on the -U flag in conjunction with specific terminal settings. cmatrix -C blue -U -s Use code with caution. cmatrix japanese font
CMatrix includes built-in support for Japanese text via the -u (UTF-8) flag and specific character sets. To force Japanese output, use the following command:
The primary way to enable Japanese characters is using the -c flag (e.g., cmatrix -c ). According to the ArchWiki, this mode uses half-width Katakana, digits, and symbols to replicate the original movie's "digital rain".
for a specific language (like Python or C) to build a custom version of this? If you don't want to recompile the original
Ensure your system locale supports UTF-8. You can check this by running locale . It should show something like en_US.UTF-8 or ja_JP.UTF-8 . Installing CMatrix Install CMatrix using your package manager: sudo apt install cmatrix Use code with caution. Fedora/RHEL: sudo dnf install cmatrix Use code with caution. Arch Linux: sudo pacman -S cmatrix Use code with caution. Running CMatrix with Japanese Fonts
You will see basic Japanese syllables like テ (Te) and ス (Su). Run cmatrix long enough, and you might even learn a Kana or two.
On Arch-based systems, the process is similar: Ensure you select a "Mono" version of the
He pressed Ctrl+C . The rain stopped.
Several community forks of cmatrix have rewritten the character generation logic to inject genuine Japanese Katakana. The most popular variant is available on GitHub. Building CMatrix with Unicode Support Install the development prerequisites:
: It authentically replicates the "Matrix" movie look using Katakana without the font-rendering bugs typical of older cmatrix builds.
