Then I suggest to add TakaoPGothic for Linux system.

On Ubuntu 16.04 and higher, the font TakaoPGothic is used to display the 
"23" in the test; the font TakaoPGothic
https://packages.ubuntu.com/xenial/fonts-takao-pgothic
comes from the installed by default (component is "main", not 
"universe") from the package
https://packages.ubuntu.com/source/xenial/fonts-takao

On Mac OS X, I suggest "Hiragino Kaku Gothic ProN" .
https://bugzilla.mozilla.org/show_bug.cgi?id=1383584#c6

Default CJK font under Ubuntu and Mac OS X for Firefox:
https://bug1383584.bmoattachments.org/attachment.cgi?id=8889237
https://bug1383584.bmoattachments.org/attachment.cgi?id=8891275

The font-family declaration would be:

pre
   {
     (...)
     font-family: "TakaoPGothic", "Hiragino Kaku Gothic ProN", "MS 
Gothic", serif;
   }

which should be perfect for Firefox on Linux/Mac/Windows systems and 
presumably also for Chrome. Regarding Edge 15+, I have no idea.

When I look at example 17 in

https://www.w3.org/TR/2015/CR-css-writing-modes-3-20151215/#text-combine-fullwidth

and if I text-select/highlight the

２
０
１
０
年
２
月
23
日

run of text, I expect the "23" to be as wide as the "月" and other glyphs 
but it is not.
