I'm guessing that it isn't a cultivar but probably a variant found in Korea..?
I can't find any info--must be a pretty special plant!

I'm thinking it's going to turn out to be a mistake for var. hondai, perhaps based on a misread tag. See description of "Koreanum" at Stanley and Sons web site.

I've sent an email to the Cox's. They left for Spain today and won't be returning for two weeks, however.

but Larry does not know where he got it from.

Somethimes I'm more rich then I thought before :0)

Euan, I found a tray full of 'Koreanum' at my nursery which I came across between the other liners which we're repotting now.

This one looks like the one at your pic, which isn't strange because it derives from that same specimen ;0)

I'll send you one together with Thujopsis dol. 'Angustifolia' and 'Compacta', but only if you like this...

Also does anyone know if the name Koreanum can be
used as a cultivar name?

Ron, you could be right about this cultivar name.
In my opinion it should be Thujopsis dolabrata var. koreana but unfortunately there's no info availlable about it...
For sure is that this one isn't the same as var. hondai because that one is an upright grower while this one is a more flat/globose one.

Maybe we should go with the idea that this cultivar
was found in Korea a sport from a normal Thujopsis.

Euan, I don't think it's found as a mutation, imo it's a local variety found in Korea.

As far as I know Thujopsis is only found in Japan
but maybe Resin knows something.

A green upright form of Japanese Elk Horn Cedar. Leaves bright green. Plant grows 2 ft. a year. Conical upright

--Stanley and Sons web site

Bushy clonal propagations grown under the same name could be behaving differently due to cultivariance, the source cuttings having come from side branches.

Korea?

At this stage the only useful information will be that which is about the actual origin of the name, the rest is becoming somewhat pointless speculation.

I emailed Aljos Farjon no new variety of
Thujopsis dolabrata in Korea so we do know
its a cultivar.

"Well Resin

No!

"Also does anyone know if the name Koreanum can be used as a cultivar name?"

No it can't, as it has a Latinised ending (unless it dates to before 1952, whch seems unlikely).
