Amazon has expanded the Prime Now service to Osaka, Japan and the surrounding area. The mobile-only service, available exclusively to Prime members, lets members select from 15,000 items, including refrigerated and frozen grocery items.  Prime Now delivers orders in as little as one hour for 890 yen, or in two hours free of charge. Order minimum is 2,500 yen. 

This marks an expansion of Prime Now in Japan, as it was already available in Tokyo and the surrounding area.
