Back to the main point of the thread (and why I revived it):
Plant of Assembly for the second gen xB: Kanegasaki, Isawa, Iwate, Japan
That area is a major rice-paddy area for rice production, but also makes superconductors and Lexus vehicles (listed several places as: Kanto Jidousha-> is that the plant name? Again, can't read Japanese). I wonder if that is the same plant that makes the xB?
Edit 2: That is a sub-company that is part of the Toyota Group and makes the Lexus SC. It is sometimes listed as the "Kanji" plant.
Edit:
The best I can tell, the xB2 is made under contact for Toyota by Central Motor Co, of Japan. I can't read Japanese or translate that to Japanese for the name (Maybe Wave Rider could help with that).
Looking at numerous websites, it looks like Toyota makes most of the vehicles in plants it owns outside Japan and contacts with various plant owners in Japan to make JDM-built vehicles, to Toyota spec and standards. Central Motor Co, must be one of those JDM companies that subcontracts for Toyota.
(Not proven fully, but suspected based upon multiple sources.
Edit 3: I need to learn more about the Japanese corporate structure . . . It seems Toyota has partial ownership of many "subcontact manufacturers" (as we would call them in the US), in part or with a controlling interest.
From this, I CAN say that Daihatsu does not make the xB2, but another Toyota owned?/operated?/contracted? company does. That company is Japanese and operates under the name of Central Motor Co.
