In Osaka the standard is just to drop your bicycle on the side of the street, to the point that people can't walk anymore on that side :P

I think in most areas of Tokyo these things really aren't necessary, despite the high popularity of bicycle transport, because bicycle parking is fairly simple to cram in various nooks and crannies (lots of bike parking underneath train viaducts), and bikes are more popular in more less dense (suburban, outlying) areas than in the densest parts of the city core, which means there's usually a bit more space available too.

When you're going to do major construction anyway, you may as well build a human-accessible bike-parking structure or underground bike-parking area, which can probably be equally dense, and are almost certainly less of a maintenance burden.

The main advantage of robo-parking seems to be that it lets them use a very vertical space, which wouldn't work so well with "manual" bike parking.
