Starting a new thread to deal with this small mystery.
What you found DimensionsTomorrow is quite curious.
As i noted earlier, Elektron.se removed their reference to their Japanese Office, and also removed reference to their Berlin Office. To my knowledge no official announcement of this was made.
I also noted at that time, that the website that Elektron Japan used ( Elektron.co.jp ) which is separate from the Elektron Sweden site ( Elektron.se ) still showed a Japanese Elektron Office.
But as you have found the Japanese web-site now redirects to the Elektron Distribution Group. This appears to me to be a Japanese Importer of three electronic music equipment brands — Elektron, ASM, and Erica Synths.
Note the logo on this site. It appears to me to be new and distinct. It doesn’t belong to any of those three companies.
A hypothesis, this is a separate company, an importer in Japan, who has rights to use the name Elektron Distribution Group, but is not part of the Swedish company. That they also have use of the old Elektron Japan web-site which redirects to the Elektron Distribution Group web-site, is quite curious.
So new thread, if anyone cares to comment further. Please keep the posting traffic down with relevant and substantial ideas.
