Japan used to have more urban monorails, back when they were seen as futuristic rather than awkward to run.
I wonder if US troops use the monorail much, or just drive around in the cars they can get shipped over from the US for free? (The US military is very serious about logistics, and letting GIs ship their Cadillacs to whichever South Pacific atoll they’re stationed on and back again afterward is both a flex and a demonstration that they can ship other stuff across the world when needed.)
