The Tokyo area has two suspended monorails. Chiba's [1] is well known. It's a big, heavy-duty system in an urban area. Less known is the Shonan line in Kanagawa Prefecture.[2] It's a single-track system with passing sidings at stations. This line was crammed into a suburban area, and there are lots of turns to get around obstacles. The support columns are in odd places. That's the monorail dream, to be able to put in a system without severe impact on the area. It's worth watching the video to see how that worked out.
