Oh, this is where it gets real fun, actually.
So here's how it works. Topre manufactures all Topre switch keyboards to my knowledge. (Not sure if it's direct or indirect.) But they do not have a distribution channel for keyboards - their primary industries are things like refrigerated trucks, industrial paint application, you get the idea.
So let's cover the brands etcetera.
Realforce - trademark and brand owned by Topre,
see herePFU Limited - contract customer of Topre for HHKB.
Leopold - Leopold is only the
distributor for only the 87U.
Diatec - AKA Filco! Distributor for 91UDK-G, 91UBY (Yellow)
JUSTSYSTEM - 91ATOX (programmable key version?)
ILOVEX -
The green and yellow monstrosity.EliteKeyboards - Exclusive United States distributor (all models) to my knowledge.
Now we're
really confused, no? Here's how supply chain works for Realforce, abridged version.
Topre makes keyboards -> keyboards go to MAIN distribution -> shipped to regional distributor (think Ingram Micro, TechData equivalent) -> regional ships to retail -> you buy your keyboard from retail.
Topre makes contract order keyboard -> keyboards go to contract customer (e.g. PFU, ILOVEX) directly -> contract customer supply chain
So for example, with the 87U what they might do is just ship
all of them to Leopold who then sells and ships to retail (e.g. EK) so that Topre doesn't have to worry about any of it. So technically they're all distributed by Leopold, since Leopold is handling the distribution chain. But for a 105U they might ship direct to certain retailers, and through distributors for other regions. Leopold won't sell them to other retail channels in the US because EK has an exclusivity agreement, but is free to sell them to anyone they want in say, Japan or Taiwan or Europe. It's very complicated and confusing, yes.
And believe it or not, this is entirely normal for Japan. The process for buying Fujitsu SPARC gear (SPARC is huge in Japan thanks to Fujitsu, too) in North America and not just Sun^WOracle-rebadged Fujitsu is virtually impossible. Getting Fujitsu
storage in North America? Yeah, I wouldn't recommend even attempting it if you value your sanity. And it's not just Fujitsu - it's pretty much everyone except Hitachi Data Systems (which is a
subsidiary of Hitachi Corporation who also sells nuclear reactors and construction equipment.) Their distribution and sales channels are all nightmares.
