I recently won this from Yahoo! Auctions Japan. It sold at a reasonable price but unfortunately the shipping was way more than the board which I guess isn't surprising due to the weight of this unit. They definitely don't make them like this anymore.

Made in 1974! Pretty sure this is the oldest Micro Switch board in my collection and certainly the only one from Japan.

This is a real interesting one. It has the classic Micro-Switch hand-traced PCB from early 70s, but a very different layout and chips from any board I've seen during that era. The 1SW11 switches are the same dual-magnetic series from the Decision-Data punch keyboards, but the caps are a completely different profile and engraved vs doubleshot. I wonder who made them? That Yamatake partnership must've been pretty big for them to include their name on the main logo.

I thought it was pretty interesting.

Also a bit of company history:

1952 Technical license agreement is signed with Honeywell Inc. (presently Honeywell International Inc.) of the U.S.
1953 Yamatake (presently Azbil Corporation) forms an equity-based alliance with Honeywell (presently Honeywell International Inc.) of the U.S. (50% share)
