The Apple Maps update is now live in Tokyo, Osaka, Nagoya, and Kyoto. The update was spotted by ATA distance from the US.
Look around is essentially Apple’s answer to Google’s Street View. You can bring it up in supported areas by tapping the binoculars icon. The transitions between photos are smoother than in Street View, which makes it feel more like you’re actually exploring the area.
