Found that a quite old (DOS era) but blazingly fast Japanese text editor, even on NEC PC-9081Vm with slooooooow i186 class (NEC V30) CPU, VZ Editor is now open to everyone with BSD 3 Clause license!

The source codes are as-was, so for MS/PC-DOS coded in 8086 assembly and for PC-9801 version, directly controlled video hardwares. This was because video BIOS and ANSI driver on PC-9801 series was unusably slooooooooow, and AFAIK ALL text editors (at least commercial ones) did as such.
But DOS/V version ran even on MVDM of OS/2 quite smoothly.
Maybe needs thoroughly overhaul to use nowadays even based on DOS/V version, as it had limitation in target file and it would be too low for large log files or source codes. And as at the ERA, Japanese version of DOS was using Shift JIS (CP832), thus no support for UTF-8.
Even though, many thanks with maximum respects to the author and former business owner who allowed the author's decision!
