I bought this mysterious keyboard as NOS on eBay about 5 years ago when I was studying Japanese and recently began using it as my main recently after my other board broke. However, I am now wondering what it is. It is a Japanese layout board made by NMB Technologies. The keys are tactile but non-clicky, and I sadly don't have a stack of nickels around at the moment for that test.
Here's a great pic of the stem with cap removed

(Sorry for the inconvenience; I evidently can't even post a single URL because I am a forums newcomer)
Any further information would be greatly appreciated! I looked around in the wikis here and searched furiously, but to no avail... Is it some random ALPS clone? A magical rare gem?
