What is reported at the page you linked is absolutely wrong: Roland Italy and Roland Europe are two different companies; the first one is the Italian distributor of Roland products and is located in Arese, near Milan; the second one has developed and manufactured the G-70 (and other previous Roland arrangers like E-70, G-1000, VA-7, etc.) and is located in Acquaviva Picena (prov. Ascoli Piceno - reg. Marche), a small town in the center of Italy near to the Adriatic Sea.
