These days, finding the installation media for the B-right/V OS itself can be hard. But the operating system is still sold on Amazon as "Chokanji V, TRON runs on Windows" input system. 超漢字V means "Super Kanji 5", by the way. There is MacOS X version, too.
Either version is just installing BTRON in VMWare, and runs the input method somewhat seamlessly.
Archive.org has installation media for B-right/V 4.5 from 2006, but it will not run in Qemu properly. https://archive.org/details/chokanji
The iso contains a file called bright00 which is a boot floppy for B-right/V installer. It should work on most i386-based computers, but it requires supported CD, IDE and mouse. After a bit of tinkering with PCem, I managed to make it work.
The installer shows not one but two splash screens: B-right/V TRON OS first, and Chokanji V second. Then it starts a very simply-looking disk partitioning and OS installing tool. Make no mistake, at this point TRON OS is already running. The mouse cursor is a bit funny/unusual, showing cup of green tea whenever there's a delay ("hourglass").
While it loads, you might contemplate: why did they bother to make a whole OS? Well, my dear friends, they needed a system that could support kanji, RTL and vertical input before Unicode was invented.
