A thought, regarding vises in Japan......
Whilst I have to agree with Outlaw, regarding the pathetic quality level of the generality of the oriental import equipment sold by importers here, there are multiple truths, to be sure.
As we all know from history, the Jap Empire built up a formidable munitions industry some 80+ years ago, with literally 'world-class' technical productive capability.
The 'small-change' of this industry, such as vises, hand tools, and light machine tools were, obviously, of 'adequate' quality to 'get the job done'.
Interestingly, I've seen very few items of apparently pre-war or war-time Jap munitions-plant tooling equipment, of this time-frame, here on the west coast, other than a few odd thingamies which somehow migrated to this country, maybe as 'souvenirs' following the war.
If you've the interest, in this modern age of internet instant communication, you might be able to make contact with someone in the modern Japanese equivalent, or parallel, of the Garage Journal site (it seems probable that they'd have one, cars are an interest everywhere), and ask about the Japanese tooling of the last century of industrialisation, and the modern tooling made in Japan for domestic use.
I've not the vaguest idea as to whether there might be any 'vise collectors' in Japan, but there could be, who could provide photos and specs of the various makes and vintages of their vises. I'd not be surprised to see British and German designs, as a generality.
From the very little i've read on the subject, the beginnings of the then-modernised Jap Navy, from 1900-ish forward, was built up by British and German firms on contract, including major shipyard machinery and tooling. It would seem plausible that such as vises were one of the many items for which drawings and patterns would be furnished, for manufacture in Japan to British or German specs, so of good quality. (whatever the quality of their tooling, the ships and munitions that tooling built were of adequately high quality to make life hell for our men in the Pacific, 70-odd years ago)
