Jet Set
Connecting Shinjuku and Shibuya with ever-trendy neighbourhoods like Shimokitazawa and Kichijoji and running all the way to Hachioji and Takao far out west, the Keio line is supremely convenient for exploring the more polished sides of suburban Tokyo and its hip cafés, family-friendly parks and underground gig spots.
Our guide to the best things to do along the Keio and Inokashira lines points the way to essential sights, fancy restaurants and art galleries frequented by western Tokyo's comparatively well-dressed and well-off natives, while also including somewhat scruffier spots like old-school cinemas, public bathhouses and no-frills boozers. Hop on and start exploring – or opt for a significantly less posh alternative with our guide to the Seibu lines.
